Manufacture of semiconductor wafers: a project manager at the U.S. company Temescal (a member of the BOC Group plc), wears "clean room" protective clothing to examine a single, gold-coated silicon wafer. Circular wafers based on silicon are used as building-blocks in the design of individual integrated circuits (silicon chips); numerous chips are constructed on a single wafer. Temescal uses electron-beam and sputter coating technologies to deposit the thin films required for the manufacture of such semiconductor wafers.
