摘要:
A resist composition comprising an alkali-soluble resin, typically a partially t-butoxycarbonylated polyhydroxystyrene, a p-butoxystyrene/t-butylacrylate copolymer or p-butoxystyrene/maleic anhydride copolymer as a dissolution inhibitor, and a iodonium or sulfonium salt as a photoacid generator is effective for forming a resist film which can be precisely and finely patterned using high energy radiation such as a KrF excimer laser.
摘要:
A resist composition comprising a base resin, an acid release agent, and a dissolution inhibitor is improved in sensitivity and resolution when the base resin is typically selected from poly-t-butoxystyrene/poly-hydroxystyrene, poly-t-butoxystyrene/poly-p-methoxymethoxystyrene/polyhydroxystyrene, and poly-t-butoxystyrene/poly-p-methoxystyrene/polyhydroxystyrene copolymers. The composition forms a resist useful for the manufacture of LSI.
摘要:
A refreshing agent comprising a compound having a hydrosilyl group and a hydrosilylation catalyst quickly adsorbs ethylene without forming hazardous substances and is thus suitable for keeping vegetables, fruits, and flowers fresh.
