Patent ID: 8431330

Claim:
A method for forming a resist pattern, comprising: forming a first resist pattern with a first resist composition; treating the first resist pattern with a surface-treating agent; and forming a second resist pattern on the first resist pattern with a second resist composition, wherein the surface-treating agent contains a compound represented by formula (1): wherein m represents an integer of from 1 to 8; R 1 represents a monovalent organic group; R 2 represents an m-valent organic group, provided that R 1 and R 2 may be bonded to each other to form a ring, and when p represents 2 or more, a plurality of R 1 's may be bonded to each other to form a ring; X represents an oxygen atom or a sulfur atom; n represents an integer of from 0 to 10; and p represents an integer of 2n+3 or less, and wherein the surface-treating agent is used in a step between a formation of the first resist pattern on a first resist film and a formation of a second resist film on the first resist pattern to form the second resist pattern.
