The earliest microprocessors in the early 1970s were PMOS processors, which initially dominated the early microprocessor industry.[5] In 1973, NEC's μCOM-4 was an early NMOS microprocessor, fabricated by the NEC LSI team, consisting of five researchers led by Sohichi Suzuki.[6][7] By the late 1970s, NMOS microprocessors had overtaken PMOS processors.[5] CMOS microprocessors were introduced in 1975.[5][8][9] However, CMOS processors did not become dominant until the 1980s.[5]
