摘要: A dendritic or hyperbranched polymer having a weight average molecular weight of 500-10,000,000 is prepared by polymerizing a hydroxystyrene derivative, adding a branching monomer midway in the polymerization step to introduce branch chains, and repeating the polymerizing and branching steps. The polymer is advantageously used as the base resin of resist material because the size of the polymer can be reduced while maintaining strength.

摘要: Novel silicon-containing polymers are obtained by copolymerizing a vinylsilane monomer with a compound having a low electron density unsaturated bond such as maleic anhydride, maleimide derivatives or tetrafluoroethylene. Using the polymers, chemical amplification positive resist compositions sensitive to high-energy radiation and having a high sensitivity and resolution at a wavelength of less than 300 nm and improved resistance to oxygen plasma etching are obtained.
