Description:

Inductively coupled plasma etcher for etching silicon with Bosch or cryogenic processes.

Key Features and Accessories:

  • Three power sources: ICP source 5 kW, HF source (13.56 MHz) 300 W (also low power can be controlled accurately by using an automatic x0.1 attenuator), LF (350 kHz) 300 W.
  • Available etch gases: SF6 (two lines for low and high flow), C4F8, O2, Ar, CHF3
  • Operating temperature with cryo from -150 °C to +110 °C and with chiller from 0 °C to +60 °C.

Substrate Size:

Wafer clamps exists in the following sizes: 100 mm, 150 mm, 200 mm, 156x156 mm2. Small samples need to be glued on a protected carrier wafer with e.g. photoresist. Al2O3 is a good masking material for the carrier.

Allowed Materials:

Si, Ge, Al, Mo, Nb, W (and their oxides and nitrides), photoresists, (TiN as an etch stop layer)

Forbidden Materials:

All other materials (including Ti, Ni, Cr)

Important for License application:

    Substrate material
    Wafer size (4", 6", 8")
    Etch process type (cryo, Bosch)
    Approximate etch depth
    Process temperature
    Mask material
    List of all the materials currently on the substrate (metals etc.)
