Latest Patents

Matsumoto's latest patents include a novel polymer for lithography. This copolymer is obtained by polymerizing two or more types of monomers. The process involves dividing an eluate showing peaks relative to the copolymer into eight fractions based on an elution curve obtained by gel permeation chromatography (GPC). Each fraction has the same volume, and the difference between the monomer composition ratio of the first eluted fraction and that of all copolymers is maintained within a range of -3 mol % to +3 mol %. Another significant patent is a method for producing a polymer that enhances variations in the content ratio and molecular weights of a copolymer's constitutional units. This method improves solvent solubility and the sensitivity of a resist composition using the polymer.
