Title: Innovations by Colin Hester in Anti-Reflective Coatings
Introduction
Colin Hester is an accomplished inventor based in Rolla, MO (US), known for his significant contributions to the field of polymeric coatings. With a total of three patents to his name, Hester has made notable advancements in the development of thermosetting polyester anti-reflective coatings.
Latest Patents
Hester's latest patents focus on thermosetting polyester anti-reflective coatings designed for multilayer applications. These coatings exhibit high optical density, rapid plasma etch rates, and high solubility in preferred coating solvents. They also provide excellent feature coverage and improved stability in solution. The principal component of these innovative coatings is a polyester resin produced through the reaction of difunctional aliphatic carboxylic acids with a stoichiometric excess of di- and/or trifunctional aliphatic primary alcohols. Notably, at least one of the dicarboxylic acids may contain a reactive methylene (--CH.sub.2--) group. The resulting polyester resin is further modified by attaching light-absorbing groups to some or all of the reactive methylene groups and/or hydroxy groups present on the resin. This dye-attached polyester resin is then combined with an aminoplast crosslinking agent and acid catalyst in a suitable solvent system to create the final anti-reflective coating.
