Abstract:
1. A method of imaging a resist in a lithographic process, comprising: forming a resist on a substrate, the resist capable of being imaged by lithographic radiation, the resist comprising: a) a polymeric matrix material, wherein the polymeric matrix material does not include substantial silicon-silicon atom bonding, b) an acid-generator for creating an acid when the resist is exposed to the lithographic radiation, and c) a sensitizer for increasing the sensitivity of the resist to the lithographic radiation, the sensitizer comprising a compound having at least one silicon-silicon bond; and applying the lithographic radiation to the resist to oxidize at least one silicon-silicon bond and thereby enhance imaging, wherein the sensitizer comprises less than about 0.10 weight fraction of the total amount of the acid-generator, the sensitizer, and the polymeric matrix material.
