Patent ID: 6989333

Claim:
A process for forming a pattern, comprising: preparing a substrate; forming a workpiece film on the surface of the substrate, and forming a resist film on top of the workpiece film, the resist film having a first glass transition temperature; disposing a mask on the surface of the substrate, and irradiating the resist film with a first energy beam through the mask; forming a first resist pattern on the surface of the substrate by developing the resist film after applying the first energy beam; irradiating the first resist pattern with a second energy beam after removal of the mask, to thereby effect a crosslinking reaction in the first resist pattern, and so that the first resist pattern is caused to have a second glass transition temperature that is higher than the first class transition temperature; forming a second resist pattern smaller than the first resist pattern by subjecting the first resist pattern to heat treatment after applying the second energy beam, the heat treatment being performed at a temperature that is higher than the first glass transition temperature; and patterning the workpiece film by use of the second resist pattern as a mask.
