Abstract: PURPOSE:To eliminate variations in impurity concentrations in an N<+> type gate and a P<+> type gate by implanting impurities to first and second polyside electrodes, then removing part of a silicide layer for constituting an upper layer of the polyside electrode of a connector, and then treating it with heat. CONSTITUTION:A polyside electrode 145 common for an N-type MOS transistor forming region 107 and a P-type MOS transistor forming region 101 of a semiconductor substrate is formed. With it N-type impurities and P-type impurities are implanted as a mask in the substrate via the regions 107, 101. A silicide layer 181 of an upper layer of a polyside electrode 147 is partly removed in a boundary between the regions 107 and 101. Then, even if it is heat treated such as source/drain implanted layers are activated, P-type impurities of a P-type gate and N-type impurities of an N-type gate are not diffused each other through a silicide film.
