Silicon Wafer Production and Specifications

Silicon Wafer Specifi cations Diameter The diameter of the silicon wafers are specifi ed either in inches or mm. Although an inch is 25.4 mm, the diameters of wafers in inches are usually multiples of 25.0 mm (e.g. 4 inches = 100 mm), which should be clarifi ed beforehand with the supplier. The tolerance of the diameter is typically +/- 0.5 mm.
