Abstract
A method of fabricating a semiconductor device capable of improving reliability of a gate insulator film is obtained. This method of fabricating a semiconductor device comprises a step of forming a gate insulator film on the main surface of a semiconductor layer by heat treatment, and the step of forming the gate insulator film includes a step of performing the heat treatment in an atmosphere containing oxidizing gas at a temperature exceeding the temperature causing viscous flow of the gate insulator film thereby forming the gate insulator film on the main surface of the semiconductor layer.
