Introduction/Precautions Operation/Maintenance Manual
i-2
Page
The AL120 series consists of a wafer loader, a vacuum stage, and other products.
This manual does not cover custom-order specifications or microscopes.
To acquire a comprehensive understanding of both your loader and microscope, please refer to your
microscope operation manual.
You must prepare yourself the table on which the loader is to be installed and the cassettes and wafers to be
inspected and loaded by the loader.
This loader is designed to maximize its operability when it is installed on a table with a height of 700 mm.
The operability is designed based on the SEMI Standard S8.
Our company’s designed operability is not guaranteed if the loader is installed on a table that does not satisfy
the conditions specified above.
Please refer to the SEMI Standard S8 to select a table.
1. Precautions
Operators must follow the instructions in the Operation/Maintenance Manual. If these instructions are not
followed, safety can not be assured, and malfunctions may occur.
The following 3 types of symbols are used in this Manual to draw operators' attention.
: Indicates critical advice in order to protect operators from injury as well as to protect the
loader (including its peripherals) from damage.
: Indicates a cautionary advice to protect the loader from damage.
: Indicates useful information for operation.

2. Safety Precautions
1. Use the loader within the scope of the specifications.
2. Use only the OLYMPUS power cord provided with the loader.
Otherwise the safety performance of the loader can not be assured.
3. The power cord plug must be easily accessible at any time. Immediately unplug the
power cord if you find any abnormalities in the loader.
4. Bind wires and tubes to table legs and the like to prevent them from catching your
feet.
5. Be sure to ground the loader. Otherwise our intended electric safety performance of
the loader cannot be assured.
6. Never put any metallic objects in the vent. This could cause an electric shock or
malfunction.
7. Place the loader and the microscope on a sturdy and level table (with a tilt angle of no
more than 1 degree).
8. Wear gloves when clearing broken wafers.
9. Wafers under inspection could fall down when the vacuum supply is stopped. The
check valve and buffer tank should be connected to maintain a vacuum even when the
vacuum supply is stopped. Buffer tank and the check valve are not attached to Wafer
Loader. When it is necessary, please contact it to nearest OLYMPUS distributor.
10. Wafers could fall down if you touch them or apply a force to them during inspection.
Do not touch wafers during inspection.
11. Undergo maintenance training before attempting to do maintenance on the loader.
12. Consult your nearest OLYMPUS distributor if you need to move the loader.
(The loader weight is approximately 44kg.)
13. Down flow that may cause a wafer to shake may cause the wafer transfer operation to
be accompanied by physical danger. Take care that the wafer transfer operation is
performed at a location where there is no such down flow.
14. Use a cassette that complies with the SEMI standard. If a deformed cassette is used,
there is an increased risk of a wafer being damaged.

15. To get the best performance from this loader, make sure that there is at least the
space shown below (with dimensions in ) around the loader during assembly
and installation.
The dimensions indicated by the dot-dot-dash lines show the stage's movable range.
You can get more working space during maintenance or other work by changing the
observation tube mounting direction and moving the stage.
This installation space is determined according to the SEMI guideline (SEMI
S8-0308). Provide adequate space for operating the loader according to your intended
use by referring to the installation space and outer dimensions shown on the next
page.

Page
3. Before Starting Operations
In order to get the best performance from the loader, as well as to ensure safety, please follow the 3
points listed below.
1. Never put your hands in the loader.
2. Do not deliberately place wafers or other objects in or remove from the loader while it is
in operation.
If excess force is applied to the wafer under inspection, it could lose its adhesiveness
and could be damaged.
3. Make sure that the main switch is turned off before removing a wafer for unavoidable
reasons such as malfunctions.
4. Maintenance and Storage
Make sure that the main switch is turned off and the power cord is unplugged before doing
any of the following operations.
1. Wipe each part of the loader using a soft cloth moistened with pure water.
Wipe heavy dirt or stains with a clean paper moistened with commercially available
absolute alcohol.
Never place absolute alcohol close to a flame as it is highly flammable.
Take care not to cause sparks by turning on or off an electric appliance or fluorescent
lamp.
2. Wear gloves to protect your hands while cleaning the loader when for example a wafer
is damaged.
3. Periodically check the loader for wear (a wafer loading arm and deterioration of the
drive mechanism), and replace the parts as needed. Contact your nearest OLYMPUS
distributor for repair.
1. Never disassemble the loader unnecessarily. This could affect the performance and
function of the loader.
2. Contact your nearest OLYMPUS distributor if you need MSDS.
3. Confirm and observe your local municipal ordinances or regulations when you dispose
of the loader.
If you have any questions, contact your nearest OLYMPUS distributor.
4. Lenses and solders used by this system are lead-free.
