Deposition of Silver
Silver can be deposited by e-beam evaporation, by sputtering and by thermal evaporation. In the chart below you can compare the different methods on the different deposition equipment.
| E-beam evaporation (Alcatel) | Thermal evaporation (Wordentec) | E-beam evaporation (PVD co-sputter/evaporation) | Sputter evaporation (PVD co-sputter/evaporation) | Sputter evaporation (Wordentec) | |
|---|---|---|---|---|---|

| Pre-clean | RF Ar clean | RF Ar clean | RF Ar clean | RF Ar clean | RF Ar clean |
| Layer thickness | 10Å to 1µm | 10Å to 0.5µm (0.5µm not on all wafers) | 10Å to 1000Å | 10Å to about 5000Å | 10Å to about 3000Å |
| Deposition rate | 2Å/s to 15Å/s | 1Å/s to 10 Å/s | About 1Å/s | Dependent on process parameters. | Depending on process paramterers (see logbook) |
