Inspection, process control and defect analysis of wafers or LCDs and TFTs
has to be fast, accurate and ergonomic. The Leica DM8000 M and DM12000 M
optical inspection microscopes provide an innovative yet cost-effective system
solution for mastering present and future manual inspection challenges with
confi dence. Beside extreme large overview capabilities and high resolution optics
these systems are incorporated in a highly ergonomic design with fully integrated
LED illumination allowing the sample to be illuminated from different angles.

The Leica DM8000 M and the Leica DM12000 M
feature an integrated macro mode, which gives
you four times the fi eld of view of conventional
scanning objectives. Seeing more means faster
throughput.
from every angle
The new Oblique UV (OUV) mode combines
oblique illumination with UV light, which enables you to view a sample in high resolution
from any angle – and enhances the accuracy
of the inspection results.
Higher quality
due to ergonomic design
An ergonomic design enables users to work in
comfort, enhancing their performance and ultimately improving the quality of their work.
The Leica DM8000 M/DM12000 M are specifi cally
designed to provide comfort for long hours at the
microscope, and are intuitively operated and easy
to adapt to different users’ microscopy skill levels.
LED illumination
for a cleaner environment
The LED illumination integrated in the
Leica DM8000 M/DM12000 M optimizes
the airfl ow and creates a cleaner cleanroom.
With their long lifetimes and low power
consumption, LEDs also have a lower cost
of ownership.

Optic – Excellent Image Quality
To achieve fast and reliable results during manual inspection within a very short time, the optical performance of the microscope is a
key element. With the Leica DM8000 M and DM12000 M, Leica Micro systems has developed a series of innovative features that support
the operator in completely new ways.

1. Macro
Overview
In the motorized versions of the Leica
DM8000 M and DM12000 M the micro/macro
option for rapid scanning of large components can be integrated. The macro objective,
which is fully parfocal with all other inspection
objectives, captures an object fi eld of approx.
40 mm on the sample – that’s almost four times
more than with conventional scanning objectives. With the Leica macro mode you detect
defects that are invisible using conventional
light microscopes, such as insuffi cient development at the edge or within the center
of a wafer. Uneven radial fi lm thicknesses are
made visible using the macro overview mode.
The entire scan area can be accurately
checked for possible defects in a fraction of
the time. If you want to take a closer look,
simply press a single button to switch from
macro to micro mode and inspect the defect
in the required contrast mode.
3. Fast Switchable UV
and OUV Contrast
Achieving a higher resolution of the sample
image is done with a single button click using
the Leica DM8000 M and DM12000 M. Pressing the UV button the visible light is cut and
the sample is illuminated in less than a second with UV light of 365 nm wavelength, thus
reducing the resolvable structure sizes down
to 0.14 µm. Just one additional button click
gives a completely new visual experience –
the OUV mode, an adjustable UV illumination
beam that allows high resolution edge inspection, for example.
With the Leica macro mode, you detect
defects that are invisible using conventional light microscopes, such as
insuffi cient development at the edge.

2. Integrated Oblique
Illumination
For a quick inspection of edges, e.g. of transparent fi lms or solar cells, the oblique illumination is integrated with every Leica DM8000 M
and DM12000 M. By pressing the OBL button, oblique illumination is activated and the
operator can decide which deviation angle α
(see picture 2) of the beam path is applied to
inspect the sample in the best way – fast, reliable, and with topographic information. The
oblique illumination is combined with visible
light contrast modes such as BF or DIC, but
also with UV light in the OUV mode.

The illumination with powerful LEDs is fully
integrated with the Leica DM8000 M and
DM12000 M stands.
4. Transmitted
Light Axis
The transmitted light axis (TL) is equipped
with a fully integrated LED illumination in the
same way as the refl ected light axis. With the
integrated LED illumination samples such as
transparent LCD panels are inspected with
brightfi eld or with polarized light.
For high precision inspection of semitranslucent devices, a single button click is enough
to activate refl ected light (RL) and transmitted
light (TL) simultaneously. Intensity, aperture,
and even contrast mode can be switched
independently for RL and TL. To inspect microscratches, for example, you can have the
OBL mode in RL and polarized light in TL at the
same time and adjust intensity and aperture
of both axes separately. This saves time during inspection and allows additional information to be gathered from the sample.
5. Fully Integrated
LED Illumination
The LED illumination is integrated within the
microscope. Without a lamphousing in the
way, there is an optimal airfl ow around the
microscope. A clean solution for the cleanroom. The powerful LEDs with a color temperature of 4,000 K have a very long lifetime
of up to 25,000 hours yet extremely low power
consumption with the highest illumination
power. For BF, DF or DIC in refl ected light the
powerful LEDs are used in the same way as
for UV illumination or transmitted light inspections. The long lifetime of the LEDs reduces
the downtime of the instrument signifi cantly
as there is no need for bulb exchange. Keep
your environment clean while saving money
and increasing productivity at the same time.

both the eyepieces and the camera port. For
UV and VIS imaging a separate upright image
ergo tube is used, ensuring that no UV light
passes the eyepieces.
10. Fast, Smooth-moving
Objective Nosepiece
Overview inspections with the macro objective, edge inspection with a 5x or 10x magnifi cation or review of small details with 100x
or 150x magnifi cation – all these steps of an
exemplary inspection workfl ow often need to
be performed in less than a minute, requiring
highest parcentration accuracy. Especially
developed for use in a cleanroom environment, the sealed 6-fold BD (M32) objective
revolver integrates two separate motors, one
for rotation and the other for fi ne movement,
resulting in fast yet completely smooth movement that is an audible sign of its long-life
quality. Comfortable use even with cleanroom
gloves is ensured by easy to reach control
buttons at the front of the instrument.
11. Focus Drive
The manual Leica DM8000 M and DM12000 M
inspection microscopes feature a precision
3-gear system, a sample protection stop, a
torque adjustment mechanism, and heightadjustable focus knobs. A total travel range of
35 mm can be adjusted in the coarse mode,
the fi ne mode or the super-fi ne mode. The
automated Leica DM8000 M and DM12000 M
inspection microscopes are outfi tted with a
motorized focus drive having a travel range of
35 mm with a minimal step size of 3.6 nm and
a maximum speed of 5 mm/sec. The electronically controlled focus drive has fi ve speeds.
Parfocal compensation can be set easily for
all objectives, which eliminates the need for
individual refocusing after objective change.
Height-adjustable
Focus Knobs
No two hands are alike. And so the manual
Leica DM8000 M and DM12000 M microscope versions enable every hand to rest
on the table while reaching the focus knobs
in complete comfort. The vertical position of
the focus knobs can be precisely adjusted to
fi t the individual user’s hand. This prevents
hand, arm, and shoulder tension and ensures
a comfortable, fatigue-free grip – without
additional arm supports.

can be signifi cantly increased without harming the quality of inspection. Three of the conveniently arranged buttons with integrated
feedback LED are located on the front of each
Leica DM8000 M or DM12000 M microscope.
Semi-motorized or motorized stands feature
4 additional buttons behind the focus knobs
to provide easy, fast access to the functions used most. Additional function buttons
are available on the external Leica STP6000
SmartTouch Panel, on the joystick or on the
Leica SmartMove remote control.
13. LEDs Displaying

speed (coarse or fi ne mode) is provided for
the user of a motorized and semi-motorized
Leica DM8000 M or DM12000 M microscope
with the integrated LED status display.
14. Motorized Aperture
Diaphragm
All Leica DM8000 M and DM12000 M feature a
motorized disk with 17 stops of various sizes,
which are saved separately for every objective. This allows aperture openings from 5%
to 100% to be approached enabling a 100%
reproducibility of the imaging conditions. Together with the light intensity this aperture
information is stored when saving an image
and can be reproduced at any time. This high
reproducibility is especially important for the
review and classifi cation of critical defects.
15. Illumination
Manager
All Leica DM8000 M and DM12000 M inspection
microscopes feature automatic Köhler light
management. This fully integrated illumination
control system detects the selected objective
and automatically sets the user defi ned values
for aperture and light intensity. This reduces
inspection time and signifi cantly supports less
experienced operators. The user can change
these illumination values according to the
requirements of the sample at any time. The
modifi ed settings are automatically saved and
used as the new default values.
The 17-position aperture disk
allows 100% reproducibility.

16. Contrast Manager
The contrast manager which is integrated
in motorized (and semi-motorized) Leica
DM8000 M or DM12000 M microscopes allows
an easy and very fast change of the contrast
mode: just press one of the programmable
function buttons and all required adjustments
of the light path for the selected contrast are
automatically set. Toggle between brightfi eld
and DF or have the UV and even the OUV
contrast adjusted within less than a single
second. This naturally covers more than just
setting the appropriate refl ector cubes on the
integrated 4 position refl ector turret; it also
includes automatic adjustment of aperture
diaphragm and light intensity.

Indicator
In addition to design features such as the
long-life objective nosepiece or the integrated LED illumination the Leica DM8000 M and
DM12000 M inspection microscopes support
the user with information concerning the service status. A service-interval indication LED
is integrated on the back of each 8” or 12” instrument.
This allows you to plan preventative maintenance well in advance and further reduces
the risk of downtime of the instrument, even
in very demanding applications.
20. Fully Integrated
Electronics
The entire electronics required for control of
nosepiece, illumination, contrasting and xyz
movement for the LED illumination of TL and RL
axis and also for the control of intensity and aperture are fully integrated into the stand of the
microscope. Without the need for control boxes
or power supplies the space around the inspection microscope is kept empty and clean.
21. Precision Inspection
and Review Stages
Depending on the requirements and the
sample size different stages are available.
The manual 8“ or 12“ inspection stages are
equipped with a fast adjustment handle. The
positioning of the coaxial drive allows onehand operation for the control of x, y and z
movement.
Both the motorized 8“ and 12“ review stages
feature a spindle drive with a ball screw pitch
of 4 mm, allowing a fast travel speed of up to
240 mm/sec and at the same time a resolution
of 0.01µm in x and y direction.
Using the motorized review stage, a point of
interest selected in the Leica Application Suite
(LAS) live image shown on the monitor is immediately positioned in the center of the fi eld
of view. For live image measurements or image analysis, this function is a key element.
A variety of different inserts for the manual
and the motorized 8“ or 12“ stages is used
depending on the size and the type of sample.
Wafer holders (chucks) for 6-8“ or for 8-12“ diameters, both with or without vacuum fi xation
or mask holders, steel plates or glass plates –
the user has a wide selection to choose from.
Due to the same internal dimensions of the
stages all inserts fi t each stage and are fully
interchangeable.
