Abstract:
A patterning process includes (1) coating and baking a first positive resist composition to form a first resist film, exposing, post-exposure baking, and alkali developing to form a first resist pattern, (2) applying a resist-modifying composition to the first resist pattern and heating to modify the first resist pattern, (3) coating and baking a second positive resist composition to form a second resist film, exposing, post-exposure baking, and alkali developing to form a second resist pattern. The modified first resist film has a contact angle with pure water of 50°-85°.
