Radiation-sensitive composition containing 1,2 quinonediazide compound, alkali-soluble resin and monooxymonocarboxylic acid ester solvent

摘要

A radiation-sensitive resin composition comprising a solution of an alkali-soluble resin and a radiation-sensitive compound in a solvent comprising a monooxymonocarboxylic acid ester. This composition has a high storage stability (i.e., a very small amount of fine particles are formed during storage) and is suited for use as a resist for making integrated circuits.
