Abstract: PURPOSE:To manufacture a minute dual-gate CMOS that sufficiently carries out an introduction and an activation of desired impurities in a gate electrode, and that has a source and a drain of a shallow junction. CONSTITUTION:After well regions 2, 3, an element separation region 4, and a gate insulation film 5 are formed in a substrate 1, polysilicons are accumulated and patterned to form gate electrodes 6a, 6b. First resist 7a is applied thereto and etched back, and the gate electrode 6a is selected by second resist 8a to carry out an ion implantation 9a of n<+>, whereby impurities are introduced into only the gate electrode 6a. Also, after the first resist 7a and second resist 8a are removed, the gate electrode 6b is selected by first resist 7b and second resist 8b to carry out an ion implantation 9b of p<+>, whereby impurities are introduced into only the gate electrode 6b. After the impurities introduced into the gate electrodes 6a, 6b are heat-activated, the source and drain of a shallow junction are formed.
