Drive C1 negative to the stop position; LED 102 lights; stop point in the range 000 -
050
Drive C2 positive to the stop position; LED 1 lights; stop point in the range 950-999
Drive C2 negative to the stop position; LED 2 lights; stop point in the range 000 - 050
If these aren’t working as stated, refer to section 5 or OIPT Work Instruction No. 39

9) Fit all covers to the AMU ensuring that they are securely fitted, and then connect the
RF generator to the matching unit. Evacuate the process chamber and turn on a low
power process.
For a Plasmalab system, a suitable process would be:
RF Generator output:
50 W
Pressure:
50 mTorr (RIE), 1 Torr (PECVD), 0.1 Torr (PE)
Gas:
20-100 sccm air, nitrogen or argon.
For an ion beam system, a suitable process would be:
RF generator output: 150 W (3 cm to 5 cm diameter)
300 W (15 cm to 20 cm diameter)
Gas:
10 sccm Argon
It may be necessary to use a gas burst to start the plasma, and it may be
necessary to start the neutralizer, if fitted.
