Polymer, resist material and patterning method |
摘要 |
Provided are a resist material having markedly high resolution and etching resistance of a practically usable level, and being useful for fine microfabrication; a patterning method using the resist material; and a polymer useful as a base resin for the resist material. More specifically, provided are a polymer having a weight-average molecular weight of 1,000 to 500,000, which comprises one or more repeating units selected from the group consisting of repeating units represented by formulae (1) to (3) below; and one or more repeating units of the formula (4) below; and a resist material containing the polymer.
