Photoresist and method for forming a relief image utilizing composition with copolymer binder having a major proportion of phenolic units and a minor proportion of non-aromatic cyclic alcoholic units

摘要

A photoresist that utilizes a copolymer of a phenol and a cyclic alcohol having increased optical transmission properties relative to photoresists using fully aromatic phenolic resins. Preferred binders are hydrogenated novolak resins and hydrogenated polyvinyl phenol resins.
