Abstract

A method of manufacturing a semiconductor device that provides a semiconductor device having improved channel mobility includes a process of forming a gate insulation film of silicon oxide film, silicon nitride film or silicon oxide nitride film or the like on a silicon oxide substrate, and following formation of the gate insulation film on the silicon oxide substrate with heat treatment for a given time at a temperature range of 900° C. to 1000° C. in an atmosphere containing not less than 25% H2O (water).
