Patent number: 6740469Abstract: Anti-reflective compositions and methods of using these compositions to form circuits are provided. The compositions comprise a polymer dissolved or dispersed in a solvent system. In a preferred embodiment, the polymers of the composition include recurring units having the formula where X is a light-attenuating moiety, M is a metal, and each R is individually selected from the group consisting of hydrogen, alkyls, aryls, alkoxys, and phenoxys. The resulting compositions are spin bowl compatible (i.e., they do not crosslink prior to the bake stages of the microlithographic processes or during storage at room temperature), are wet developable, and have superior optical properties.Type: GrantFiled: June 25, 2002Date of Patent: May 25, 2004Assignee: Brewer Science Inc.Inventors: Vandana Krishnamurthy, Charles J. Neef, Juliet A. M. Snook
