Process optimization using the Picoscope
The original standard recipes on Pegasus 1 differ in many ways. The second step of one of them is listed below:
| Process A Step 2 parameters | ||
|---|---|---|
| Parameter | Etch | Dep |
| Gas flow (sccm) | SF6 350 (1.5 s), 550 | C4F8 200 |
| Cycle time (secs) | 7.0 | 4.0 |
| Pressure (mtorr) | 25 (1.5 s), 150 | 25 |
| Coil power (W) | 2800 | 2000 |
| Platen power (W) | 140 (1.5) 45 | 0 |
| Common | Temperature 20 degs | |
When running any recipe on theSPTS Pro software Using the SPTS Pro soft
