Abstract

A semiconductor device manufacturing method includes the steps of forming a silicate film by performing a first step of forming a metal oxide film on a silicon substrate, and a second step of inducing a solid phase reaction between the metal oxide film and a surface of the silicon substrate by heat treatment, and forming a high dielectric constant insulating film on the silicate film.
