Gold coated Si wafers and Si chips
Nano-Tec gold coated silicon wafers and chips are useful for thin film research, AFM / SPM, nanotechnology and biotechnology applications. The silicon wafers and chips are coated with 50nm of pure gold over a 5nm adhesion layer of chromium. Both chromium and gold are deposited in a dedicated high vacuum deposition system using electron beam evaporation sources. The gold coating is not atomically flat – there are height differences in the nanometre range. The maximum use temperature is around 175°C – higher temperatures could result in delamination of the gold film.
Available in two silicon wafer sizes: Ø2”/51mm and Ø4”/100mm and Si chips 10 x 10mm. Nano-Tec gold coated wafers are individually packed in wafer carrier trays for protection. Nano-Tec gold coated Si chips are packed in a Gel-Pak box.
