Patent ID: 7776515

Claim:
A method for forming a pattern of a semiconductor device, comprising: (a) forming an underlying layer on a semiconductor substrate; (b) forming a first organic hard mask film on the underlying layer, the first organic hard mask film consisting of: (i) a polyamic acid compound represented by Formula 1: (ii) a melamine derivative represented by Formula 5: and (iii) an organic solvent; (c) forming a second hard mask film on the first organic hard mask film, said second hard mask film defining a surface; (d) forming a photoresist pattern on the resultant surface of (c); (e) patterning the second hard mask film using the photoresist pattern as an etching mask to form a second hard mask film pattern; (f) patterning the first organic hard mask film using the second hard mask film pattern as an etching mask to form a double hard mask film pattern of the first organic hard mask film pattern and second hard mask film pattern; and (g) patterning an underlying layer using the double hard mask film pattern as an etching mask to form an underlying pattern.
