Abstract

A method for manufacturing a semiconductor device including: forming a resist film 11 on a film to be processed 32; baking the resist film 11; performing immersion exposure on the resist film 11 after the baking; performing post exposure bake on the resist film 11 after performing the immersion exposure; developing the resist film 11 after performing the post exposure bake; and after the post exposure bake is performed on the resist film 11, removing an edge 15 of the resist film 11, the edge not being exposed.

Claims

exact text as granted — not AI-modified
1 .- 6 . (canceled) 
     
     
         7 . A method for manufacturing a semiconductor device comprising:
 forming a resist film on a film to be processed;   baking the resist film;   performing immersion exposure on the resist film after the baking;   performing post exposure bake on the resist film after performing the immersion exposure;   performing wafer edge exposure on an edge of the resist film after performing the post exposure bake;   heating the edge of the resist film simultaneously or after performing the wafer edge exposure on the edge of the resist film; and   developing the resist film after the edge of the resist film is heated.   
     
     
         8 . The method for manufacturing a semiconductor device according to  claim 7 , wherein the edge of the resist film is heated to a temperature higher than ambient temperature. 
     
     
         9 . The method for manufacturing a semiconductor device according to  claim 7 , wherein the edge of the resist film is heated by infrared ray irradiation. 
     
     
         10 . The method for manufacturing a semiconductor device according to  claim 7 , wherein a region of the resist film except for the edge of the resist film is cooled at the time when the edge of the resist film is heated. 
     
     
         11 . (canceled) 
     
     
         12 . A method for manufacturing a semiconductor device comprising:
 forming a resist film on a film to be processed;   baking the resist film;   performing immersion exposure on the resist film after the baking;   performing wafer edge exposure on an edge of the resist film after performing the immersion exposure;   performing post exposure bake on the resist film after performing the wafer edge exposure;   developing the resist film after performing the post exposure bake; and   cooling the resist film after performing the immersion exposure on the resist film and before performing the post exposure bake on the resist film.   
     
     
         13 . The method for manufacturing a semiconductor device according to  claim 12 , wherein the resist film is cooled before performing the wafer edge exposure on the edge of the resist film. 
     
     
         14 . The method for manufacturing a semiconductor device according to  claim 12 , wherein the resist film is cooled to a temperature lower than ambient temperature.
