Manufacture of semiconductor wafers: an engineer at the U.S. company Temescal (a member of The BOC Group plc), wears "clean room" protective clothing to check tolerances on a vacuum chamber belonging to Temescal's SCS 1500 single wafer deposition system. Semiconductor wafers 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 components.
