Abstract: A new kind of acid-sensitive polymer with Tg=95℃ and Mn=7625, Mw=25013 (Mw/Mn=3.28) was synthesized by the co-polymerization of styrene, N-(4-hydroxyphenyl) maleimide and methylacrylamidoglycolate methylether(MAGME). This MAGME containing co-polymer can be self-crosslinked via acid-catalyzed condensation reaction when heated. A new kind of chemically amplified negative photoresist without crosslinking agent was studied using this co-polymer as the base resin, which was developable in harmless NaOH-H2O solution. Diaryliodonium hexafluorophosphate was used in the photoresist as the photo-acid generator to supply the strong acid and phenothiazine was the photosensitizer. The condition of photolithography was preliminarily investigated.

Key words: self-crosslinking, water-developable, chemically amplified, negative photoresist
