    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: The precursor composition of silicon carbide fibers provided by the invention has greatly improved spinnability and can be spun at a very high spinning velocity to give a green filament which has a much larger tensile strength than those of conventional precursor materials and is capable of giving silicon carbide fibers having increased tensile strength by the infusibilization and calcination of the green filament of the composition under tension. The composition comprises from 80 to 99.9 parts by weight of a polycarbosilane polymer and from 20 to 0.01 part by weight of a silmethylene polymer having a degree of polymerization larger than the specified lower limit.
