Abstract:
A semiconductor device to be used for a CMOS inverter circuit, the semiconductor device comprising:a dielectric film formed on a semiconductor substrate; a SOI film comprising single crystal Si formed on the dielectric layer film; a gate dielectric film formed on the SOI film; a gate electrode formed on the gate dielectric film; and a diffusion layer for source/drain regions formed in source/drain regions of the SOI film, wherein, when a power supply voltage of 0.6 V is used, a thickness of the SOI film is 0.084 &mgr;m or greater and 0.094 &mgr;m or smaller, and an impurity concentration of the SOI film is 7.95Ã—1017/cm3 or greater and 8.05Ã—1017/cm3 or smaller.
