Procedure: |
- Check Equipment Reservations in CORAL to
insure that you reserved the correct machine for the correct
date. Another user may have reservations. It is your responsibility
to honor them, if this is the case.
- In CORAL Use the "ENGAGE" command
from the “EQUIPMENT ACTIONS” drop window, followed
by “ENTER RUN DATA” from the “ROUTINE ACTIONS” drop
window for the equipment that you are about to use. Insure
that the correct facility is set (ICL) and that your lot name
is entered correctly. Enter the number of wafers that you are
processing and the film type as well as the thickness of the
deposition you’re planning to do.
- Venting the system:
This procedure will take approximately 5-7 minutes for completion.
- On the Ion Gauge Controller Press the button
labeled IG1. (This will turn the ion gauge OFF)
- On the
vacuum controller press the (red) System
STOP button.
- On the vacuum controller press the (Yellow) System
Vent button.
- Following the instructions
given during the training, proceed to remove the planetary
in the chamber Using the planetary holder as instructed.
- Use a vacuum hose to vacuum out any debris and flakes from
the process chamber.
- Switch the shutter to “Open” position,
and load the material you are planning to used for your deposition,
taking note what pocket of the hearth you are Using. (Pocket
A is reserved for Al only). Switch the shutter back to “Auto”
- Load your wafers onto the planetary facing down, insuring
they are held by both clips on the side that will NOT be processed.
- Re-install the planetary on the chamber as previously instructed.
- Wipe the O-ring; hold close the chamber lid, while pressing
the (green) System Start button on the Vacuum controller. The
chamber will go to high Vacuum. It will take approximately
3.5 hours for 5e-7 chamber pressure to be achieved. DO NOT
Disengage the system during this time.
- Find the film you
are planning to use in the process binder located by the system.
Unlock the “Deposition Controller” and
enter the desired process for the material you are planning
to deposit on your wafers, obtained from the e-beam binder.
When done, insure to lock the “Deposition Controller"
- After correct
vacuum pressure has been obtained:
- Turn ON Main Power Supply,
- Turning ON the High Voltage Controller
- Turn ON the
Electron Gun Controller.
- Test the filament current by
depressing the testing switch. The needle should indicate
about .2 Amps
- On the Deposition Controller, press the reset button to
insure it all begins at zero.
- Press the start button on
the Deposition controller to begin your process. (the timer
begins running, and your deposition will be in progress)
- After the LED indicating Process Complete had turned ON,
allow 20minutes before the next step is performed.
- Repeat
step number 3 from this procedure (This will vent the chamber
after the process is done)
- Remove your wafers and place
the planetary back in the chamber.
- NOTE: When the deposition
has been Ni (Nickel) you MUST load an Al target, set the Deposition
controller for an aluminum deposition process and perform a
deposition of 1000Å (100nm) to coat the entire chamber
in order to avoid cross contamination to other users’ process
- When done, In CORAL Use the "DISENGAGE" command
from the “EQUIPMENT ACTIONS” drop window to complete
your operation. Enter all pertinent information as required.
