Remove AZ resist in the AOE using the recipe Descum
| Parameter | Descum |
|---|---|
| Coil Power [W] | 2000 |
| Platen Power [W] | 30 |
| Platen temperature [oC] | 0 |
| O flow [sccm] | 99 |
| Pressure [mTorr] | 10.0 (strike pressure 20.0 mTorr) |
| Typical results | tested by bge@danchip |
|---|---|
| AZ resist etch rate | ~41 nm/s |
BARC etching
