    摘要: Excellent resolution and sensitivity in the patterning of resists utilized in device and mask manufacture is obtained with a specific composition. In particular this composition involves polymers having recurring pendant acid labile .alpha.-alkoxyalkyl carboxylic acid ester moieties in the presence of an acid generator activated by actinic radiation such as UV-visible, deep ultraviolet, e-beam and x-ray radiation.

    摘要: Tris(dialkylamino)sulfonium bifluoride salts are obtained by hydrolysis, methanolysis, or pyrolysis of corresponding tris(dialkylamino)sulfonium difluorotrimethylsilicates, reaction of dialkylaminotrialkylsilanes with sulfur tetrafluoride, or reaction of bis(dialkylamino)sulfur difluorides with dialkylamines. These bifluoride salts, which have the general formula (R.sup.1 R.sup.2 N)(R.sup.3 R.sup.4 N)(R.sup.5 R.sup.6 N)S.sup..sym. HF.sub.2.sup..crclbar., are useful polymerization catalysts.

    摘要: Replacement of the amorphous peptide domain of a structural biopolymer, such as silk from silkworms or spiders, with a nonpeptide segment while maintaining the β-sheet forming crystalline segments provides synthetic multiblock copolymers having solid-state structures and mechanical properties similar to the naturally occurring structural biopolymer is described herein. Such synthetic multiblock copolymers may be produced as films or fibers.
