Frank Marion Wanlass (May 17, 1933, in Thatcher, AZ – September 9, 2010, in Santa Clara, California) was an American electrical engineer. He is best known for inventing CMOS (complementary MOS) logic in 1963. CMOS has since become the standard semiconductor device fabrication process for MOSFETs (metal–oxide–semiconductor field-effect transistors).
