RF POWER SUPPLY and MATCHINGBOX

8. Troubleshooting

8-1-2. Matching box troubleshooting

Table 8-2 Matching box troubleshooting list

No.

Problem

Cause

The matching point has changed.

①

The gas pressure, distance between ES, or

substrate load conditions have changed.

②

Wiring or screws inside the matching box are

loose or missing.

Reflected wave power (Pr) does not

decrease.

①

Insufficient matching adjustment

②

No discharge due to the gas pressure, distance

between ES, or substrate load conditions.

Variable capacitors not operating in

manual mode.

①

A RF Generator internal control element has

broken.

②

Mechanical breakdown or deterioration of the

variable capacitors or couplings.

③

Communication cable break or poor connector

contact.

The auto matching operation is not

performed in auto matching mode.

①

The matching mode is not AUTO.

②

For external control, pins 34 and 35 of

"EXT.CONT", the external control connector, are

short circuited (manual mode)

③

A RF Generator internal control element or the

controller has broken.
