Title: Hiroshi Okazaki: Innovator in Resist Composition Technology
Introduction
Hiroshi Okazaki is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of resist compositions, particularly in the development of innovative processes for preparing these materials. With a total of 3 patents to his name, Okazaki's work has had a considerable impact on the industry.
Latest Patents
One of Okazaki's latest patents involves a process for preparing resists. This resist composition is created by reacting an alkali-soluble polymer that contains phenolic hydroxyl or carboxyl groups with a vinyl ether compound in an aprotic solvent, such as propylene glycol monomethyl ether acetate, in the presence of an acid catalyst. The reaction is suspended by adding a base, and a photoacid generator is directly incorporated into the reaction solution. Additionally, when a dialkyl dicarbonate is used instead of the vinyl ether compound, a resist composition can be prepared by conducting the reaction with a basic catalyst and directly adding a photoacid generator. This innovative approach allows for the preparation of resist compositions without the need to isolate or purify the alkali-soluble polymer that has been modified through catalytic reactions.
