PolySilicon can be sputtered in Alcatel and be deposited in the PolySilicon furnace.

Tin can be deposited by e-beam evaporation. In the chart below you can compare the different deposition equipment.


Sputter (Alcatel) Furnace PolySi

  • Up to 1x4" wafers
  • smaller pieces
  • 8x4" wafers or
  • 5x6" wafers
Pre-clean RF Ar clean Ar ion bombartment
Layer thickness 10Å to 1µm 10Å to 1500Å
Deposition rate 2Å/s to 15Å/s 1Å/s to 5Å/s
