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.
