Abstract:
1. A semiconductor device comprising: a semiconductor substrate; an insulated gate type transistor formed in said semiconductor substrate; and an insulated gate type capacitor formed in said semiconductor substrate; said insulated gate type transistor including: said insulated gate type capacitor including: said insulated gate type transistor has pocket regions of the transistor of a reverse conductivity type to that of said source-drain regions formed from said source-drain regions to a part of said body region of the transistor, said insulated gate type capacitor has no region of a reverse conductivity type to that of said extraction electrode regions in a vicinal region of said extraction electrode regions in said body region side of the capacitor, said source-drain regions include an extension portion of the transistor which has an upper layer portion protruded partially toward said body region side of the transistor, said extraction electrode regions include an extension portion of the capacitor which has an upper layer portion protruded partially toward said body region side of the capacitor, and said extension portion of the capacitor and said extension portion of the transistor being set to have impurity concentrations equal to each other.
