Automated IC Inspection Microscope
Automated IC Inspection Microscope L200A
The next generation in automated
IC inspection microscopy
The Eclipse L200A has scored major
advances in the standardization of
inspection and safeguards against
contamination. In a new design that
combines motorized control with
automated operation, observation
conditions can be programmed for
each individual objective or for each
substrate to be inspected. Focus position,
objective magnification, illumination control
and other microscope methods are fully
programmable and can be recalled instantly.
This eliminates deviation in inspection
results that might occur due to different
settings made by multiple users.
To minimize the chance of
contamination, the L200A's aperture
control and other major operations
are now motorized, enabling remote
control for use on unattended IC
production lines. Like other Eclipse-
series microscopes from Nikon, the
L200A features industry-acclaimed CFI60
infinity optics.
Include an ergonomic design for comfortable
viewing, a rigid, vibration resistant
construction, and you have a microscope
unsurpassed to meet the stringent
requirements of the latest semiconductor fabs.
The L200A is the next step upward in
automated IC inspection microscopy.

Motorized, remote control minimizes
the chance of contamination, while
enhancing productivity
Frequently used operations such as aperture control, focusing, brightfield-
darkfield changeover, nosepiece rotation, lamp intensity control, and DIC
setting (option) are all motorized and can be controlled by the remote
controller or a PC. In addition, there is virtually no operation that requires
manual adjustment above the sample, therefore preventing particle
contamination introduced from the operator.
Free from deviations in
inspection results, due to
human errors and differences in
microscope settings
Optimum observation conditions including focus position,
aperture, light intensity, as well as DIC prism and polarizer
position can be preset objective-by-objective and recalled
simply by selecting the objective. This eliminates the need
to configure these settings each time the microscope is
used, providing standardized observation regardless of
who operates the microscope.

Remote Controller
Easy configuration into an automated inspection system
Programmed settings
As an inspection process varies depending on substrate,
layer, and even the operator, it has been necessary to re-
adjust settings for each inspection process.
The L200A's programming feature eliminates this process.
You just select the settings-such as observation method,
objective magnification, point to be checked, focus
position, aperture, and light intensity-and save them by
attaching appropriate file names. All you need do to begin
your inspection is just to specify the file name.

In combination with
wafer loaders
Of course, the L200A can be configured with
Nikon's NWL-860 series of wafer loaders and
manual or motorized scanning stages to
create a wafer inspection system at a
minimum cost.
DART Software is an integrated software package
that can fully automate the inspection process.
DART combined with an NWL860 wafer loader,
ISS200 Motorized Stage and a L200A Auto Focus
offers a complete automated wafer inspection
station. DART software modules allow further
upgrades with options such as image archiving,
defect review, post probe review and online
communications.

High-contrast darkfield images
A new illumination
system produces a
Signal to Background
(S/B) ratio that is
nearly three times
greater than former
models. This
improves sensitivity
during darkfield
observations, enabling the detection of minute scratches
and surface irregularities within the sample, and provides
exceptionally high contrast.

DXM1200 digital camera
The DXM1200 Digital Camera achieves ultra-
high-quality digital images equivalent to
approximately 12 million output pixels, plus
has a low-noise design for clear, low-light
image capture. The camera's software can be
set to automatically categorize the images
taken, sort them and save them, all
automatically—a powerful feature when you
take a large number of photomicrographs.

Centerable motorized
nosepiece
The sextuple motorized
nosepiece not only has
the same encoded
positioning system
offered on the Eclipse
L200, but it also offers
three adjustable objective
positions that improve
par-centricity even more.
Safeguards against
contamination
The body of this microscope is finished with electrostatic
discharge (ESD) coatings to prevent foreign particles from
adhering to it. Furthermore, the motorized nosepiece uses
a shielded center-motor that traps foreign particles inside,
preventing them from falling onto the sample.
Vibration-isolation design
Thanks to Computer-Aided
Engineering, the L200A is three
times less susceptible to
floor vibrations when
compared with conventional
models in this class. This
reduces the chance of
unwanted blur or image
shifts even during high-
magnification
observations.

Nikon's renowned CFI60 optics are the fusion of CF design
and infinity optics. These new optics feature longer working
distances and high N.A.'s. They also produce brighter
images with more contrast and reduced flare.
Optical System
A tilting trinocular eyepiece tube with a lower eyepoint
designed to be closer to the operator allows you to sit in a
more natural erect position. Microscope controls located
comfortably up-front in the microscope base minimize
hand movement, allowing you to concentrate on the
inspection process.
