NanoFab Tool: Plasma Therm Corial Deep Silicon Etcher

Plasma-Therm Deep Silicon Etcher

The Plasma-Therm deep silicon etcher is an inductively coupled plasma (ICP) reactive ion etching system used for etching deep features in silicon. The tool uses a fast switching Bosch process that produces vertical sidewall profiles. The manual load system can accommodate substrates ranging from 200 mm diameter wafers down to small pieces.

Specifications/Capabilities

  • Inductively coupled plasma (ICP) power source: up to 2000 W.
  • Radio Frequency (RF) power source: up to 600 W.
  • Process gases: Ar, O2, He, N2, CHF3, C4F8 and SF6
  • Anisotropic deep etching of silicon.

Usage Information

Supported Sample Sizes

  • Maximum wafer diameter: 200 mm.
  • Small pieces supported: Yes.

Typical Applications

  • Microelectromechanical systems (MEMS).
  • Nanoelectromechanical systems (NEMS).
  • Through silicon vias (TSV) for three dimensional integration.
  • Microfluidic devices.
