Silver Coated Silicone Wafers

Substrate

Silicon Wafer (Prime Grade)

  • Type/Dopant: P/Boron
  • Orientation: <100>
  • Resistivity: 1-50 ohm-cm
  • Front Surface: Polished
  • Back Surface: Etched

Coating

Silver, Ag

  • Purity: 99.99%
  • Deposition Technique: Electron Beam
  • Deposition Rate: 1-2 Å/sec
  • Vapor Pressure: 10-6 Torr

Substrata offers a full suite of silver coated silicon wafers at affordable prices.

All coatings are deposited under vacuum using electron beam evaporation. Applications include reflectometry, nanotechnology, and AFM applications.

We use a thin titanium adhesion layer between the silicon and silver coating. This adhesion layer is optional and can also be replaced with chromium upon request. All wafers are packed in a clean environment and shipped in individual wafer carriers.
