Pattern forming process

摘要

Disclosed herein is a pattern forming process comprising the steps of coating a substrate with a photosensitive resin composition comprising a polyamic compound having, at each terminal thereof, an actinic ray-sensitive functional group which has substituent groups each having a photopolymerizable carbon-carbon double bond, a photosensitive auxiliary having a photopolymerizable functional group, a photopolymerization initiator, and a solvent to form a film; subjecting the film to pattering exposure; and then developing the thus-exposed film with an alkaline developer or alkaline aqueous solution.
