This manual is applicable for ET wafer only. This ET wafer will only work with SensArray Tool (Plasma Suites) This chapter discusses the features of the EtchTemp Wafer System. The EtchTemp Wafer System The ET Wafer has a complete measurement system embedded in the wafer to record thermal surveys in semiconductor processing equipment without the need for wired connections. Embedding the components within the wafer allows it to be treated like a production wafer in most equipment, as long as it is within the operating temperature range of the wafer. The ET wafer system consists of an EtchTemp Wafer, a carrier station/FOUP for communicating with and recharging the wafer, a USB cable, a laptop computer, and a CD containing the software and drivers needed by the system. The systems can acquire data from 1 to 64 analog channels, depending on the model. The analog channels are divided into banks. Each bank is made up of up to 8 wafer sensors. Measurements taken by the sensors are converted from analog to digital signals within the onboard electronics. Acquiring Data Utilizing the EtchTemp Wafer to acquire temperature data in your equipment is a simple process. Measurement parameters, such as sensors to be used, scan rate, time delay, etc., are set up using the Controller software. The wafer is then transferred to the measurement chamber from a FOUP or cassette via robotic arms, and the thermal measurement survey data is acquired. After the survey is complete, the data can be retrieved from the onboard memory through the RF FOUP or carrier station. The data may then be analyzed using SensArray Tool (Plasma Suites) Analyzing Data The data files acquired by the EtchTemp Wafer may be analyzed using SensArray tool. The SensArray Tools software enables users to maximize their fab’s wafer yield, by capturing real-time tool or track conditions, and identifying the performance characteristics of chambers or plates with the highest yields. Users can then modify other chambers or plates to match those characteristics, as well as monitor tools or tracks over time, to fine-tune performance. For more information on the use of the Analysis portion of the SensArray Tools, please refer to the SensArray Tools (Plasma Suites) Manual. 86-3820 Version-1.0 EtchTemp Wafer User Manual 1-2 KLA-Tencor Confidential Figure 1-1 SensArray Tools Main Screen Figure 1-2 Mission Controller Screen 86-3820 Version-1.0 EtchTemp Wafer User Manual Overview Overview KLA-Tencor Confidential 1-3 During acquisition, EtchTemp wafer performs computations on acquired data, such as determining the minimum, maximum, mean, range (max-min), and standard deviation of all wafer sensor values for the sample, and logs the results in columns. These computed values are referred to as calculated values. After acquiring, linearizing, and storing the sensor data, you can display or print the data as a line plot graph, as shown in Figure 1-3. In addition, you can display data in a table or as a wafer map. Figure 1-3 Displaying Data on a Line Plot Graph 86-3820 Version-1.0 EtchTemp Wafer User Manual KLA-Tencor Confidential 2-1 Chapter-2 System Setup Before you can begin working with the EtchTemp Wafer system, you need to unpack the system components, prepare the equipment for transfer to the Cleanroom, and charge the wafer batteries. Before You Begin Before using the EtchTemp Wafer, there are several safety and handling precautions that should be noted. Please read the information provided in this manual and become familiar with the EtchTemp Wafer before attempting your first thermal survey. • Operation of EtchTemp outside of its specified temperature range could result in unreliable readings and/or damaged wafers. Please review the recommended operating range for your particular model of EtchTemp Wafer. • Rotational speeds up to 5000 rpm have been tested and found to be safe. While it is possible that even higher rotational speed might be reached without damage to the wafer or spin plate, SensArray cannot provide any guarantees above 5000 rpm. Proper Wafer Handling Procedures: While the EtchTemp Wafer is designed to survive in a semiconductor fabrication environment, reasonable care must be taken to prevent damage to the components on the wafer, or breaking the wafer. • Always wear gloves whenever you handle the wafer. • Hold the wafer by the edges only or support from the backside of the wafer with your hand or with a vacuum wand. In some situations, you may have to grasp the edge of the wafer with your gloved fingers to prevent dropping the wafer, as when you try to insert the wafer into your equipment or a carrier station. • Never place the wafer on an uneven surface. A small downward pressure on the wafer applied at the right point could cause the wafer to break or cause cracks within the silicon. Unpacking Your System Inventory all items and compare to the packing list included with the shipment. Retain all packaging materials for the system. This is required for the return of the EtchTemp Wafer for repairs or recalibration. If any parts are missing or damaged, contact SensArray immediately. Be prepared to provide a list of the missing and/or damaged components, the Purchase Order Number, and the SensArray Sales Order Number. NOTE: Do not return components without contacting SensArray first and obtaining a Return Material Authorization. When returning components to SensArray, you must repack the equipment in the original packing material. Failure to properly pack the components may result in additional damage to the equipment. 86-3820 Version-1.0 EtchTemp Wafer User Manual 2-2 KLA-Tencor Confidential System Setup Removing the Wafer from the Storage Case: The wafer storage case is designed to keep the EtchTemp Wafer batteries charged to the optimum level for an extended period of 1 to 2 years. This is done by periodically checking the status of the batteries and recharging the batteries when their voltage drops below a threshold. CAUTION: The storage case is not designed to be used to recharge wafers after acquiring data. The storage case may not be used as a carrier station. It is used only to store a wafer when the wafer is not in use. The wafer will be maintained in the storage case until it is needed. To use the wafer, place the horizontal wafer Storage case right side up (electronic is at the bottom) on a clean work surface, as shown in Figure 2-1. To open the lid, place both thumbs on the rings on the lid as shown, lift both of your pointer fingers and open the lid completely. Locate the Charge and Communication (C/C) Carrier Station or RF FOUP near the storage case. Snap rings Storage case top side Figure 2-1 Opening the Storage Case For checking the wafer health using the storage case, make sure the storage case is completely closed. Flip the storage with the bottom side facing up as shown below. At the bottom of the storage case, there is an LCD screen that indicates the wafer serial number and battery voltage. If the wafer is not viable, the screen will indicate ‘no wafer present’. The storage case must be reset to force it to search for a wafer by pressing the reset button. The module will then spend approximately 15 seconds looking for a wafer in its presence. If a wafer is present and the module is unable to detect the wafer, try to place the wafer in the carrier station to check the wafer state. If wafer looks healthy in the carrier, the storage case may be problematic. Contact SensArray technical support for help. Storage case bottom side Figure 2-2 Storage case bottom side 86-3820 Version-1.0 EtchTemp Wafer User Manual System Setup KLA-Tencor Confidential 2-3 Charging the Equipment Before Use: Place the EtchTemp Wafer into the carrier station shipped with the unit to maintain the charge on the internal batteries. Please see Using the Charge and Communication Carrier Station for more information on inserting and removing the wafer to and from the carrier stations. Plug the laptop into the AC power supply and fully charge the laptop battery. Setting up the Software The EtchTemp Wafer system normally includes a SensArray qualified laptop computer that has been prepared with all needed software to setup, run, and retrieve data from the EtchTemp Wafer. Note that, EtchTemp wafer will only work with SensArray Tool 2.1 and above Preparing Equipment for the Cleanroom Cleaning the Equipment: When installing a computer and an EtchTemp Wafer system in the Cleanroom, follow industry standards, including wiping down the computer and the exterior of the carrier station with Cleanroom wipes dampened with de-ionized (DI) water and/or isopropyl alcohol. Wipe down the EtchTemp Wafer itself. Cleaning the EtchTemp Wafer: Significant efforts are made to keep wafers clean during the manufacturing process. Due to the nature of some processes and demands by customers for cleaner wafers, the EtchTemp wafer is now offered as a cleaned product. It has gone through a SC1 and SC2 cleaning process to remove metals and organics. The cleaned wafer is packaged in the clean single polycarbonate storage case until it can be used. Despite our best efforts, the EtchTemp Wafer may pick up contaminants from repeated handling. The ideal method of cleaning surface contaminants from the wafer is to blow a gentle stream of CDA or inert nitrogen across the surface. However, some forms of surface contamination cannot be removed this easily. The wafer can be cleaned with IPA or DI water and a cleanroom cloth. Due to the design nature of the EtchTemp Wafer, scratches in the coating on the backside of the wafer may exist. This has not been shown to cause degradation in the performance of the wafer. A gentle stream of DI water or IPA may be used to loosen surface contamination, and then use CDA or inert nitrogen to blow the surface dry. Never place the wafer in an ultrasonic cleaning bath. The vibration set up by the ultrasonics may damage the electronics inside and render the wafer inoperable. NOTE: After a period of usage under etch environment, there will be a deposited polymer ring at the bottom surface of the wafer, this may cause the chucking problem or temperature range is not in specification. Please refer to application note for the cleaning details for this polymer ring. 86-3820 Version-1.0 EtchTemp Wafer User Manual 2-4 KLA-Tencor Confidential System Setup Cleaning the Carrier Station: The carrier station is easily cleaned by wiping the surfaces with a cleanroom cloth dampened with IPA. Nothing harsher is needed to remove contamination from the surface. Be sure to clean the interior of the carrier station. Debris on the surface may cause stress points on the EtchTemp Wafer when the lid is closed. To avoid damage to the EtchTemp Wafer, only clean the interior of the carrier when the wafer is not present. Recharging and Storing EtchTemp Wafer: The carrier station contains removable, rechargeable lithium-ion batteries. The carrier station batteries should maintain a charge on the wafer batteries for up to three years. The carrier station batteries can be charged via USB or with the provided power adapter. VERY IMPORTANT! Keep the wafer stored in a carrier station when not making thermal surveys. This will help ensure the maximum lifetime for the onboard wafer batteries. When storing the wafer in the carrier for extended periods of time, confirm that the LCD display reads “Wafer Ready”. This indicates that the carrier station has established proper contact with the wafer and ensures that the wafer battery charge is being maintained. 86-3820 Version-1.0 EtchTemp Wafer User Manual KLA-Tencor Confidential 3-1 Chapter-3 Using the Charge & Communication Carrier Station/RF FOUP The Carrier Station/RF FOUP provides a method of charging and communicating with the wafer through an RF signal rather than a set of contact pins. EtchTemp wafer will only work with SensArray Tool 2.1 and above. Using the Carrier Station Before using the carrier station with EtchTemp Wafer, make sure the carrier firmware version is compatible. Carrier firmware version needs to be 2.1.90 or above. Please refer to the attached firmware upgrade document for further details. The carrier station protects the Wafer and maintains the battery charge during storage. It also provides the communication link between the Wafer and the host computer. The carrier station provides an easy, non-contact means of preparing the wafer for data acquisition and to perform data retrieval. It is important to follow proper procedures in removing and inserting the wafer in the carrier station to avoid damaging the wafer.

There are four LEDs on the left side of the carrier base, as referenced in Table 3-1. The green LED comes on when the USB cable is connected and there is communication between the host computer and the carrier station. The yellow LED will flicker when transferring data to and from the wafer. The red LED is on when the batteries are charging. When the red LED is flashing rapidly and solid, the unit is actively charging the batteries on the Wafer. It should typically take less than 10 minutes to fully charge the batteries. If it is flashing slowly, the battery charge is being maintained. Though the carrier will continue to maintain the batteries on the wafer, the red LED will flicker every 10 to 20 seconds when the USB cable is not connected to a power source. The blue LED blinks when a wafer is detected and communicating with the carrier. 86-3820 Version-1.0 EtchTemp Wafer User Manual 3-2 KLA-Tencor Confidential Using the Carrier Station Table 3-1: LED status indicators LED color Indicates Green Successful USB connection to computer Yellow USB communications activity Red Wafer Charging Blue Communication received from wafer Red/Blue alternating Wafer measurement has been initiated Carrier reset switc h Green LED USB port Yellow LED Red LED Blue LED Figure 3-2 Connections and LED Indicators Removable rechargeable battery Figure 3-3 Backside of C/C Carrier 86-3820 Version-1.0 EtchTemp Wafer User Manual Using the Carrier Station KLA-Tencor Confidential 3-3 Figure 3-4 LCD Display Figure 3-5 C/C Carrier Station Closed To open the carrier station and gain access to the wafer, push in the white Delrin cover latch button as shown in Figure 3-6 and lift the handle attached to the lid.

A groove is provided on the right-hand side of the carrier station surface to allow you to get your finger below the side of the wafer as shown in Figure 3-9. Slide the wafer to the left until there is enough of the wafer free of the carrier plastic insert surface to put your other hand or a vacuum wand under the wafer. Remove the wafer completely. Do not pull the wafer too quickly off the plastic insert surface. Static attraction between the bottom of the wafer and the plastic insert surface may place undue stress on the Wafer and result in breakage. Finger groove Remove in this direction only Vacuum wand or finger groove Figure 3-9 Wafer Removal Points Remove wafer in this direction only Figure 3-10 Removing the Wafer from the Carrier Station You can now place the wafer in a wafer cassette or other loading mechanism to perform the thermal survey. CAUTION: Only handle the wafer from the bottom or by the edges as much as possible. Always ensure the backside of wafer is cleaned of any particle or any other materials. 86-3820 Version-1.0 EtchTemp Wafer User Manual 3-6 KLA-Tencor Confidential Using the Carrier Station Using the Wafer with the Carrier Station To place the wafer on the carrier station, first open the lid of the carrier station. Slide the wafer onto the plastic insert surface and slightly push the wafer against the wafer positioners. Make sure the edge of the wafer slides under the top surface of the positioners. Once the wafer is positioned correctly, pull the wafer clamp out from the recess, lift it up, and slowly slide the clamp forward until it presses against the wafer. Release the clamp. Lower the lid until the latch contacts the locking pin. Press the locking pin in and lower the lid until the locking pin pops out as shown in Figure 3-11. The lid is now secure.

Figure 4-15 Select an ODF to load window 86-3820 Version-1.0 EtchTemp Wafer User Manual 4-13 KLA-Tencor Confidential Software Using the SensArray Tools Identifying Data to Be Analyzed Using a Template A template defines the regions of interest within a mission run using a specific recipe. It also defines the important statistics for each region (such as mean, range, and standard deviation).Templates are an important part of SensArray Tools analysis modules, because they are used to extract key information from the raw data. This section is a guide to the template creation process. The process of identifying data to be analyzed using a template, is comprised of the following steps: Step 1 - Create a Template Step 2 - Define the Intervals of Interest for this Recipe Step 3 - Define the Parameters Step 1 - Create a Template To create a template 1. Start the Create a Template module from the PlasmaSuite window. The Templates - Available Templates window opens. NOTE: If this is the first time the utility is started, the Available Templates list is empty, and no graph data is displayed. Figure 4-16 Templates - Available Templates window 2. Click the Add New Template button to start the Template Wizard to create a template, -or- the Copy Selected Template button to copy an existing template. The Mission Selection window opens. This allows a choice of reference mission, which should be a good representative of mission data collected using the recipe of interest. 86-3820 Version-1.0 EtchTemp Wafer User Manual Using the SensArray Tools Software KLA-Tencor Confidential 4-14 Figure 4-17 Mission Selection Window 3. Filter the missions by Recipe, Fab, DataSet, Wafer ID, Date, Included Missions, Data Type, Notes, or Diameter, to limit the number of missions from which to select. NOTE: More than one mission can be selected for this step, to ensure that the program is able to properly analyze other missions from the same recipe. 4. Drag the selected missions to the Selected Missions list. TIP: When selecting a single mission using the Mission Selector window, it is not necessary to drag the mission to the Selected Missions list. Instead, select the mission to be analyzed, then click the OK button. 5. After all missions are selected, click the Next > button. The Templates – Interval Definition window opens. Proceed to Step 2 - Define the Intervals of Interest for this Recipe. Step 2 - Define the Intervals of Interest for this Recipe Intervals of interest are periods of time within the data that contain “interesting” information. Typically, these are the steady state portions of the graph, where the data is not significantly rising nor falling. To define recipe template intervals of interest: 1. Select which mission to list as the reference mission in the Selected Missions box. If there are no missions in the list that represent the needed data, return to Step 1 - Create a Template. NOTE: When selecting the reference mission, start with a well-functioning chamber or track that has missions running the same recipe or flow. Identify, as the reference mission, the template that most or all the selected missions match. To do this, select each mission, in turn, as the reference mission, then compare the results by clicking the Preview button. 86-3820 Version-1.0 EtchTemp Wafer User Manual 4-15 KLA-Tencor Confidential Software Using the SensArray Tools Figure 4-18 Templates - Interval Definition Window 2. Click the Add button, to add an interval. An interval defines the mission subset to be analyzed.

Then press and hold the key while dragging a portion of the interval. Drag the beginning part of the interval to alter the start time. Drag the end of an interval to change the end time. To move the entire interval, drag the middle of the interval. 3. Click the Preview button, to see whether the intervals created are correctly matched in other missions. The preview graphs in the lower-right sector updates with the matching intervals. 4. To remove an interval, select the interval to be removed, then click the Remove Selected button. 5. If the selected intervals are satisfactory, click the Next > button. The Templates - Parameter Definition window opens. Proceed to Step 3 - Define the Parameters. Step 3 - Define the Parameters The final step in creating a template involves defining the values to be extracted from the data inside each defined interval. For example, during a plasma etch step, it may be important to measure the average wafer temperature and cross-wafer range. During this step, these extracted parameters are specified and the template is named. In addition, these statistics can be extracted from a subset of the sensors, to extract regional information. For example, it may be interesting to extract the mean temperature at the edge of the wafer only, in addition to the entire cross-wafer average. 86-3820 Version-1.0 EtchTemp Wafer User Manual Using the SensArray Tools Software KLA-Tencor Confidential 4-16 To define template parameters: 1. Click the Add New Parameter button to add a parameter. A new row appears in the Interval Parameters list, with a drop-down list for Interval, Statistic, and Sensor Pattern.

TIP: When selecting a single mission using the Mission Selector window, it is unnecessary to drag the mission to the Selected Missions list. Instead, select the mission to be analyzed, then click the OK button. 4. Click the OK button. The Go/No-Go window opens, defaulted to the Mission Data tab. The mission is loaded and the analysis results are presented. If the mission is within spec, the data and the Go/No-Go Status area are shaded green. 86-3820 Version-1.0 EtchTemp Wafer User Manual Using the SensArray Tools Software KLA-Tencor Confidential 4-22 Figure 4-27 5. If any parameters are out of spec, the data and/or the Go/No-Go Status area are shaded red, to alert that the mission did not pass. NOTES: The Overlay tab presents a graph of the selected mission mean, compared to the template mission mean. The Template tab presents, for reference, the original mission used for the template. The 2D Comparison tab provides surface plots of the selected and template missions. The Difference graph presents the differences between the selected mission and template. 6. To select a different interval, click a different row of the data table at the top. Selecting a different interval updates the 2D surface plots. 7. If the mission is red, further analysis of the process can be performed, using PlasmaRX. To access the application, click the Start PlasmaRX button (located in the lower-right area of the window). PlasmaRX The PlasmaRx module allows the user to model fab chamber behavior. The generated model displays the effect that modifying different equipment parameters has on the measured wafer data. For example, PlasmaRx can be used to show the temperature rise (at all points on the wafer) of an increase in source power. Models can then be compared (tool-to-tool, or day-to-day) to determine whether tools are performing optimally, and to help pinpoint problem components. SPC Charting The SPC (Statistical Process Control) Charting module allows the user to view SPC charts, scatter plots, and histograms for multiple missions. This provides the ability for the users to 86-3820 Version-1.0 EtchTemp Wafer User Manual 4-23 KLA-Tencor Confidential Software Using the SensArray Tools review trend information for a specific chamber, to ensure the chamber remains within spec over time. SPC Charting requires a template for the recipe to be analyzed. If an appropriate template is not available, refer to the Identifying Data to Be Analyzed Using a Template - Step 1 - Create a Template section. NOTE: If the Warning dialog box, “Some missions could not be matched to template and were removed from analysis,” opens when running SPC Charting, it means: The mission does not resemble the reference template. Click the Show Mission button in the Warning dialog box, to verify that the excluded missions do not match the template. Choose a better template as the reference. Contact KLA Tencor SensArray, if neither of the above actions resolve the problem. Match Analyzer The Match Analyzer module allows the user to compare two or more chambers running the same recipe. The data provided from this module allows the user to easily identify chambers that have fallen out of spec. Match Analyzer requires a template for the recipe to be analyzed. If an appropriate template is not available, refer to the Identifying Data to Be Analyzed Using a Template - Step 1 - Create a Template section. Profile Comparison The Profile Comparison module simultaneously displays line graphs and 2-D surface plots for two or more missions. Profile comparison requires a template for the recipe to be analyzed. If an appropriate template is not available, refer to the Identifying Data to Be Analyzed Using a Template - Step 1 - Create a Template section. AutoCal - Temperature Optimization The AutoCal module accurately measures, monitors, and calibrates the thermal dose in the post-exposure bake (PEB) step of the lithography process. Ensuring uniform temperature control across the wafer results in significant improvement in critical dimension (CD) uniformity, thereby increasing wafer yield. AutoCal includes Create Track and Create Litho Flow Wizards, to aid in setting up the lithography fab. See OnWafer Technologies, AutoCal 2.0, user documentation for further details. AutoCD - Critical Dimension Optimization Critical dimension measures transistor gate sizes on the wafer. The more uniform the gate size, the higher the total wafer yield. The object is to counteract non-uniformity resulting from previous production steps. In this case, it may not be a uniform temperature across the wafer that maximizes the critical dimension, but a different temperature on different parts of the wafer in subsequent production steps. AutoCD automatically tunes the post-exposure bakeplate settings, to achieve the desired critical dimension results on the wafer. 86-3820 Version-1.0 EtchTemp Wafer User Manual Using the SensArray Tools Software KLA-Tencor Confidential 4-24 AutoCD includes Create Track and Create Litho Flow Wizards, to aid in setting up the lithography fab. This section provides instructions for the following data management tasks: Importing Files and Data Backing Up and Restoring the SensArray Tools Database Importing Files and Data A data tag is a set of metadata for a mission. This metadata includes the name of the person who collected the data, the chamber and recipe upon which the mission was run, the date the mission was run, and notes. The information for the metadata tags was input during Fab Configuration. The Data Importing and Tagging module is used to import legacy data formats, and modify existing data tags. Legacy data is saved to the SensArray Tools database and a data tag is created for each file imported. Legacy formats currently include OnWafer data files (WFR), SensArray Excel files (XLS, TXT), and AE Pilot wafer data (CSV).

If the Software materially fails to conform to the limited warranty set forth in Section 7.1 (Limited Warranty), K-T shall, at its sole discretion (i) repair or replace the non-conforming Software to remedy the non-conformity identified by Customer in accordance with Section 7.3 (Warranty Period); or (ii) refund to Customer the amounts paid for the Software in exchange for return of the non-conforming Software, in which case all licenses granted to Customer under these Standalone Software License Terms for such Software shall be automatically revoked. This Software warranty does not obligate K-T to provide any on-site repair or on-site replacement of Software. At K-T’s discretion, repair of the Software may be made in later releases of Software and may require the purchase of additional software or hardware at Customer’s expense. THE REMEDIES EXPRESSLY PROVIDED IN THIS SECTION 7.2 WILL BE CUSTOMER’S SOLE AND EXCLUSIVE REMEDIES AND SHALL BE IN LIEU OF ANY OTHER RIGHTS OR REMEDIES CUSTOMER MAY HAVE AGAINST K-T WITH RESPECT TO ANY NON-CONFORMANCE OF SOFTWARE. 7.3 Warranty Period. Unless K-T expressly specifies or agrees on a different warranty period in a duly signed writing, the warranty period for Software shall be ninety (90) days. The warranty period shall begin on the Delivery Date. Customer shall have no warranty claims under Section 7.1 (Limited Warranty), unless K-T receives from Customer, during the warranty period (i) a written notice describing the warranty breach in reasonable detail (“Warranty Claim”); and (ii) remote and physical access to the affected Software as well as information in sufficient detail to enable K-T to reproduce and analyze the failure. 7.4 Costs and Procedure. If K-T receives a Warranty Claim in accordance with Section 7.1 (Limited Warranty), Section 7.3 (Warranty Period), and any procedure guidelines that K-T may publish or make available to Customer (“Warranty Guidelines”), K-T will not charge for any repair, replacement, error identification, or correction of the non-conforming Software. If Customer’s Warranty Claim fails to meet any of the requirements of Sections 7.1 (Limited Warranty), Section 7.3 (Warranty Period), or the Warranty Guidelines, K-T’s then-current Time & Materials Services Terms (available on request) shall apply to any error identification or correction efforts, repair, replacement, and shipment costs by K-T and Customer shall compensate K-T accordingly on a time & materials basis at K-T’s then-current rates (available on request). 7.5 Disclaimer. EXCEPT AS SPECIFIED IN SECTION 7.1 (LIMITED WARRANTY), K-T MAKES NO EXPRESS REPRESENTATIONS OR WARRANTIES WITH REGARD TO ANY SOFTWARE. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, K-T DISCLAIMS ALL IMPLIED WARRANTIES AND REPRESENTATIONS, INCLUDING, BUT NOT LIMITED TO, ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT AND, WITHOUT LIMITING THE FOREGOING, MAKES NO WARRANTY THAT THE SOFTWARE WILL BE ERROR-FREE, THAT ITS PERFORMANCE OR OPERATION WILL BE UNINTERRUPTED, OR THAT THE SOFTWARE WILL PERFORM ON ANY HARDWARE OR WITH ANY SOFTWARE, EXCEPT AS EXPRESSLY CERTIFIED AS INTEROPERABLE BY K-T IN THE APPLICABLE DOCUMENTATION. 8. TERMINATION 86-3820 Version-1.0 EtchTemp Wafer User Manual Software License Terms 4-37 8.1 Termination for Cause. Without limiting Section 3.1 (License Grant) with respect to the automatic termination of license rights for specific Software, K-T may terminate – at K-T’s sole discretion either all or specific – licenses to Software granted hereunder, by giving written notice, effective immediately, if within ten (10) days of Customer’s receipt of a reasonably detailed written request to cure, Customer has not cured all breaches of payment obligations, license limitations and restrictions, including, but not limited to, the License Parameters, or any other substantial obligations under these Standalone Software License Terms. Upon such termination, Customer shall immediately pay all outstanding fees, cease use of all Software and related Documentation, return or delete, at K-T’s request and sole discretion, all copies of the Software and Documentation in Customer’s possession, and certify compliance with all foregoing obligations to K-T in writing. These termination rights are in addition to any other rights and remedies that K-T may have at law or in equity. 8.2 Survival. K-T’s General Terms and these Standalone Software License Terms, except Sections 2.1 (Delivery) and 3.1 (License Grant), shall survive termination of any or all licenses granted hereunder. 9. AUDIT. CUSTOMER AGREES TO KEEP COMPLETE, CORRECT AND DETAILED RECORDS RELATING TO (I) THE REPRODUCTION AND USE OF THE SOFTWARE AND DOCUMENTATION, INCLUDING, AT A MINIMUM, THE LOCATION OF ALL SOFTWARE, LICENSED COMPUTERS, AND BACK-UP COPIES OF SOFTWARE AND DOCUMENTATION; AND (II) THE TRANSFER OF HARDWARE OR MEDIA ON WHICH ANY SOFTWARE IS EMBEDDED OR OTHERWISE CONTAINED AND CUSTOMER’S COMPLIANCE WITH ITS OBLIGATIONS UNDER SECTION 5 (TRANSFERS AND OTHER ACTIONS UNDER MANDATORY LAW). AT K-T’S REQUEST AND UPON TEN (10) DAYS PRIOR WRITTEN NOTICE, K-T AND/OR ITS AUTHORIZED REPRESENTATIVES (E.G., AN ACCOUNTANT AND/OR COMPUTER EXPERT) – COLLECTIVELY, THE “AUDITORS” – SHALL HAVE THE RIGHT TO INSPECT AND AUDIT CUSTOMER’S COMPLIANCE WITH THESE STANDALONE SOFTWARE LICENSE TERMS AT CUSTOMER’S FACILITIES AND OTHER APPLICABLE LOCATIONS, AT ANY TIME, DURING NORMAL BUSINESS HOURS, BUT NO MORE THAN TWICE PER YEAR. CUSTOMER SHALL FULLY COOPERATE WITH SUCH AUDIT, AND GRANT ALL REQUIRED ASSISTANCE AND ACCESS TO ALL RECORDS, MATERIALS AND EQUIPMENT. IF AN AUDIT REVEALS THAT CUSTOMER POSSESSES OR AT ANY TIME POSSESSED UNLICENSED COPIES OF THE SOFTWARE OR DOCUMENTATION, OR THAT CUSTOMER DID NOT REMOVE OR DELETE ALL COPIES OF SOFTWARE AND DOCUMENTATION THAT CUSTOMER WAS OBLIGATED TO REMOVE OR DELETE IN ACCORDANCE WITH SECTION 5 (TRANSFERS AND OTHER ACTIONS UNDER MANDATORY LAW), CUSTOMER SHALL IMMEDIATELY PAY FOR SUCH COPIES THE GREATER OF THE FEES APPLICABLE PER K-T’S STANDARD RATES AND PRICES AT THE TIME OF (A) CONTRACT FORMATION; (B) CUSTOMER’S UNAUTHORIZED COPYING; OR (C) THE COMPLETION OF THE AUDIT. IF SUCH FEES AMOUNT TO MORE THAN TEN PERCENT (10 %) OF THE AMOUNT PREVIOUSLY PAID OR PAYABLE TO K-T UNDER THESE STANDALONE SOFTWARE LICENSE TERMS FOR THE AUDITED TIME PERIOD THEN (Y) CUSTOMER SHALL REIMBURSE K-T FOR ALL EXPENSES RELATED TO THE AUDIT; AND (Z) K-T SHALL HAVE THE RIGHT TO IMMEDIATELY TERMINATE – AT ITS SOLE DISCRETION EITHER ALL OR ONLY THE AFFECTED – LICENSES BY GIVING WRITTEN NOTICE, EFFECTIVE IMMEDIATELY. THE AUDITORS SHALL NOT DISCLOSE ANY OF CUSTOMER’S INFORMATION EXCEPT AS RELATED TO ANY NON-COMPLIANCE WITH THESE STANDALONE SOFTWARE LICENSE TERMS OR INFRINGEMENTS OF K-T’S RIGHTS. K-T’S RIGHTS AND REMEDIES UNDER THIS SECTION 9 SHALL BE IN ADDITION TO AND NOT IN LIEU OF ANY OTHER RIGHTS OR REMEDIES THAT ARE AVAILABLE TO K-T AT LAW OR IN EQUITY. 86-3820 Version-1.0 EtchTemp Wafer User Manual KLA-Tencor Confidential A-1 Appendix A Reference Information Sensor Bank Reference Sensor S0 S1 S2 S3 S4 S5 S6 S7 S8 S9 S10 S11 S12 S13 S14 S15 S16 S17 S18 S19 S20 S21 S22 S23 S24 S25 S26 S27 S28 S29 S30 S31 S32 S33 S34 S35 S36 S37 S38 S39 Sensor Name A01 B02 B03 B04 B05 C06 C07 C08 C09 D10 D11 D12 D13 D14 D15 D16 D17 E18 E19 E20 E21 E22 E23 E24 E25 F26 F27 F28 F29 F30 F31 F32 F33 G34 G35 G36 G37 G38 G39 G40 86-3820 Version-1.0 Radius(mm) 37 37 37 37 74 74 74 74 74 74 74 74 92.2 92.2 92.2 92.2 92.2 92.2 92.2 92.2 110 110 110 110 110 110 110 110 140 140 140 140 140 140 140 Angle 352.5 82.5 172.5 262.5 307.5 37.5 127.5 217.5 307.5 352.5 37.5 82.5 127.5 172.5 217.5 262.5 330 15 60 105 150 195 240 285 307.5 352.5 37.5 82.5 127.5 172.5 217.5 262.5 330 15 60 105 150 195 240 X(mm) 8.9 1.2 -8.9 -1.2 22.5 29.4 -22.5 -29.4 45 73.4 58.7 9.7 -45 -73.4 -58.7 -9.7 79.8 89.1 46.1 -23.9 -79.8 -89.1 -46.1 23.9 67 109.1 87.3 14.4 -67 -109.1 -87.3 -14.4 121.2 135.2 70 -36.2 -121.2 -135.2 -70 Y(mm) -1.2 8.9 1.2 -8.9 -29.4 22.5 29.4 -22.5 -58.7 -9.7 45 73.4 58.7 9.7 -45 -73.4 -46.1 23.9 79.8 89.1 46.1 -23.9 -79.8 -89.1 -87.3 -14.4 67 109.1 87.3 14.4 -67 -109.1 -70 36.2 121.2 135.2 70 -36.2 -121.2 EtchTemp Wafer User Manual A-2 S40 S41 S42 S43 S44 S45 S46 S47 S48 S49 S50 S51 S52 S53 S54 S55 S56 S57 S58 S59 S60 S61 S62 S63 S64 KLA-Tencor Confidential G41 H42 H43 H44 H45 H46 H47 H48 H49 J50 J51 J52 J53 J54 J55 J56 J57 J58 J59 J60 J61 J62 J63 J64 J65 86-3820 Version-1.0 140 144 144 144 144 144 144 144 144 147 147 147 147 147 147 147 147 147 147 147 147 147 147 147 147 285 330 15 60 105 150 195 240 285 307.5 330 352.5 15 37.5 60 82.5 105 127.5 150 172.5 195 217.5 240 262.5 285 36.2 124.7 139.1 72 -37.3 -124.7 -139.1 -72 37.3 89.5 127.3 145.7 142 116.6 73.5 19.2 -38 -89.5 -127.3 -145.7 -142 -116.6 -73.5 -19.2 38 Reference Information -135.2 -72 37.3 124.7 139.1 72 -37.3 -124.7 -139.1 -116.6 -73.5 -19.2 38 89.5 127.3 145.7 142 116.6 73.5 19.2 -38 -89.5 -127.3 -145.7 -142 EtchTemp Wafer User Manual Reference Information KLA-Tencor Confidential Correlating Sensor Coordinates 86-3820 Version-1.0 EtchTemp Wafer User Manual A-3 A-4 86-3820 Version-1.0 KLA-Tencor Confidential EtchTemp Wafer User Manual Reference Information
