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.

US5679060A - Wafer grinding machine - Google Patents
The wafer grinding machine uses a centrally located robot to move a wafer from an input station to a measuring station. Thereafter, the wafer is moved into a grind station and a wash station sequentially. The robot is able to move a wafer from the wash station to either the measuring station for after-grinding measurements or directly to an output station.
