Silver coated silicon wafers
Nano-Tec silver coated silicon wafers are useful for applications such as thin film research, AFM / SPM, nanotechnology, reflectometry and optical applications. The silicon wafers are coated with pure silver over an adhesion layer of Ti. Both Ti and Ag are deposited in a dedicated high vacuum deposition system with electron beam (EB) evaporation sources. The silver coating is not atomically flat – there are height differences in the nm range.
The available silver coating thicknesses are: 10 nm, 50 nm, 100 nm and 500 nm. Available in three silicon wafer sizes: Ø2”/51mm, 3”/76mm and Ø4”/100mm). The Nano-Tec silver coated wafers are individually packed in wafer carrier trays for protection.
