Abstract:
A semiconductor device, comprising:a first-conductivity type semiconductor substrate; an insulating film formed on said semiconductor substrate; a gate electrode formed on said semiconductor substrate via said insulating film; and a second-conductivity type source/drain region formed on both sides of a channel forming region located under said gate electrode formed on said semiconductor substrate via said insulating film; wherein said insulating film is one of a silicon nitric oxide film and a stacked film of a silicon nitride film and a silicon oxide film, and a channel direction length (Lg) of said gate electrode and a silicon oxide equivalent thickness (Iox) of said insulating film are determined by the following relationship; Lg&lE;10(Toxâˆ’2.02) and Tox<2.5 â€ƒwhere a unit of Lg is &mgr;m and a unit of Tox is nm.
