Patent ID: 8795951

Claim:
A method for producing a semiconductor device, comprising: applying a material for forming a resist sensitization film onto a processing surface so as to form a resist sensitization film; applying a resist onto the resist sensitization film so as to form a resist film; exposing the resist film to exposure light, and developing the exposed resist film so as to form a resist pattern; and etching the processing surface using the resist pattern as a mask so as to pattern the processing surface, wherein the material for forming a resist sensitization film comprises: a metal salt; a resin; and a solvent, wherein the metal salt is at least one selected from the group consisting of a potassium salt, a rubidium salt, a strontium salt, and a cesium salt, wherein the metal salt is contained in an amount of 1% by mass to 50% by mass relative to the amount of the resin, and wherein the resin is at least one selected from the group consisting of polymethylmethacrylate, poly-p-hydroxystyrene, polyvinyl alcohol, and 3-amino-4-methoxybenzene sulfonic acid polymer.
