Product Description


These 2" (50.8mm), 3" (76.2mm) and 4" (102mm) diameter silicon wafers can be used either as substrates for thin-film research or to make small silicon substrates by dicing the wafer into smaller pieces using a scriber. Wafers generally have flats or notches cut into one or more sides indicating the crystallographic plane and doping type. These silicon wafers are available as P-type (boron-doped) wafers which are cut with a primary flat. The wafers are 230 - 575µm thick polished on one side and do not have a silicon dioxide top coating. Each wafer is shipped in a wafer carrier.
