Our gold (Au) material is 99.999% pure and is deposited onto p-type <100> silicon (Prime grade) using electron beam evaporation. We use a thin 2-7 nm layer of chromium (99.99%) as an adhesion promoter for all our gold coatings. All substrates are pre-cleaned using an ion source for quality assurance.
At Angstrom Engineering we take pride in offering high quality Substrata products and services at affordable prices.
