Patent ID: 8871432

Claim:
A pattern-forming method sequentially comprising the steps of: (1) providing a resist underlayer film on an upper face side of a substrate by coating a resist underlayer film-forming composition containing a resin having phenolic structures, each of the phenolic structures has a phenolic hydroxyl group; (2) forming a resist pattern on an upper face side of the resist underlayer film; (3) dry etching at least the resist underlayer film and the substrate, with the aid of the resist pattern as a mask to form a pattern on the substrate; and (4) removing the resist underlayer film on the substrate with a basic solution, wherein at least a part of the phenolic structures of the resin in the step of providing a resist underlayer film are modified to quinone structures which replace the at least a part of the phenolic structures, and wherein the resin is heated at a temperature of at least 200° C. under an ambient oxygen concentration of no less than 5% by volume to modify the at least a part of the phenolic structures.
