Specific Process Knowledge/Thin film deposition/Deposition of Silicon
PolySilicon can be sputtered in Alcatel and be deposited in the PolySilicon furnace.In the chart below you can compare the two different deposition methodes:
| Sputter (Alcatel) | Furnace PolySi | |
|---|---|---|
| Batch size |
|
|
| Pre-clean | RF Ar clean | |
| Layer thickness | 10Å to 1µm | |
| Deposition rate | 2Å/s to 15Å/s | |
| Process temperature | ||
| Step coverage | ||
| Film quality | ||
| Substrate material allowed |
Sputtered Silicon in the Alcatel
| The parameter(s) changed | New value(s) | Deposition rate |
|---|---|---|
| Standard parameters | None | |
| Power | 400W | 3.8 Å/s |
