Abstract:
A semiconductor device, comprising:a gate electrode formed on a substrate through a gate insulating film lying therebetween; first and second diffused layers formed opposite to each other across the portion of the substrate existing under the gate electrode and having a first conduction type, each having a second conduction type different from the first conduction type of the portion; a wiring layer formed above the gate electrode; a contact hole formed between the wiring layer and the substrate, said contact hole having a width which spans the gate electrode and the first diffused layer; a contact formed within the contact hole and electrically connecting the wiring layer to the first diffused layer and to the gate electrode, another gate electrode formed on the substrate through another gate insulating film; and a transistor for composing a semiconductor IC therein, wherein the relative dielectric constant of the gate insulating film is higher than the one of said another gate insulating film.
