 As one of the first companies to produce semiconductor wafers, MEMC was a pioneer in the field, and some of its innovations became industry standards into the 21st century.MEMC used the Czochralski process (CZ process) of silicon crystal production, and developed the Chemical Mechanical Polishing (CMP) process of wafer finishing.In 1966 MEMC installed its first reactors for the production of epitaxial wafers, and developed zero-dislocation crystal growing, which made large-diameter silicon crystals possible.
