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 shipped in individual wafer carriers.
