Abstract:
PURPOSE: A method for manufacturing a semiconductor device is provided to efficiently eliminate a residue with a simple and cheap process by eliminating the residue like scum remaining on a substrate through wet processing using acid diffusion. CONSTITUTION: A resist pattern(30P) is formed on a partial area of a substrate(10). A descum solution(50) including a acid source is touched with an outcome on which the resist pattern is formed. A resist residue(30S) remaining on the substrate surface is dissolved by using acid which is obtained from the acid source in the descum solution. A dissolved residue and the descum solution are removed from the substrate.
