Silicon Wafer (Prime Grade)

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

Coating

Gold, Au

  • Purity: 99.999%
  • Deposition Technique: Electron Beam

  • Adhesion Layer: Cr (99.99%)

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

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

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