Abstract:
A method of forming a resist pattern, said method comprising:(1) forming at least one resist layer on a working substrate by coating the working substrate with a resist composition, the resist composition comprising a silicon containing polymer which comprises as a main structural unit a structure represented by formula 1: â€ƒwhere R1 represents a monovalent organic group; R2 represents a direct bond or a divalent organic group; R3 represents a monovalent organic group or an organosilyl group, any of which groups may be of different types; X represents hydrogen, a monovalent organic group or an organosilyl group, which groups may be of different types; k and l are positive integers; m and n are 0 or positive integers, and these subscripts satisfy the following relationship: 0<11+m+n&LessFullEqual;0.8&it;â€ƒ&it;0&LessFullEqual;m1+m<0.2(2) exposing the resist layer to light and developing the resist layer so as to form a resist pattern.
