Abstract

A composite resist of poly(olefin sulfones), specifically poly(2-methyl-l-pentene sulfone), and poly(hydroxy styrenes), specifically brominat- ed poly(hydroxy styrene), is a highly sensitive and high resolution deep UV-photoresist, active below 300 nm wavelength, in negative tone, although partially developed positive tone patterns can be obtained by skipping a post-baking process.
