Patent ID: 7223518

Claim:
A composition, comprising: a polymer resin, wherein the polymer resin is a polynorbornene, wherein the polymer resin does not substantially absorb about 1 to 450 nanometer (nm) wavelength energy; and a photoacid generator, wherein the photoacid generator does substantially absorb about 1 to 450 nanometer (nm) wavelength energy, wherein the composition has a ratio of a second dissolution rate divided by a first dissolution rate that is greater than about 1.1, and wherein the first dissolution rate is measured prior the composition being exposed to about 1 to 450 nm wavelength energy and the second dissolution rate is measured after the composition is exposed to about 1 to 450 nm wavelength energy without post thermal exposure, wherein the first dissolution rate and the second dissolution rate are measured upon introduction to an aqueous alkaline developer, wherein the photoacid generator is selected from di-(p-t-butyl) phenyliodonium bis(perfluoromethanesulfonyl) imide, di-(p-t-butyl) phenyliodonium bis(perfluoroethanesulfonyl) imide, di-(p-t-butyl) phenyliodonium bis(perfluoropropanesulfonyl) imide, di-(p-t-butyl) phenyliodonium bis(perfluoromethanesulfonyl) imide tris(perfluoromethanesulfonyl) methide, bis(p-tert-butylphenyl)iodonium antimonate, and combinations thereof.
