A method of manufacturing a semiconductor device, includes: a first resist film formation process of forming a first resist film on a processing target surface using a positive-type photoresist material; a first resist pattern formation process of forming a first resist pattern by performing development after exposure in which light is irradiated onto the first resist film; a second resist film formation process of forming a second resist film on the processing target surface, where the first resist pattern is formed, using a photoresist material; and a second resist pattern formation process of forming a second resist pattern by performing exposure in which light is irradiated onto the second resist film and then performing development. The method further includes an insolubilization process for insolubilizing the first resist pattern against a developer and a solvent of a photoresist material used in the second resist pattern formation process.
