FORMATION OF ETCH-RESISTANT RESISTS THROUGH PREFERENTIAL PERMEATION

摘要

A method is provided for creation of oxygen etch-resistant polymeric films for use in the production of micron and submicron dimension patterns and fine lines. These etch-resistant polymeric films find use in fabrication of complex structures such as those in electronic devices and magnetic thin film heads. The etch resistance is achieved by incorporation of a protective-oxide forming metal into a polymeric material using preferential permeation of organometallic materials into the polymeric material.
