<p>Resists for use in ultraviolet, electron beam and x-ray exposure devices comprising a polymeric or molecular composition the solubility of which is dependent upon the presence of acid removable protecting groups and a sulfonic acid precursor which generates a strong acid upon exposure to such radiation. The preferred sulfonic acid precursors are triflate esters or benzenesulfonyloxy esters of N-hydroxyimides.</p> |
