Title: Innovations by Masaru Takeshita: A Pioneer in Resist Technology
Introduction
Masaru Takeshita, a distinguished inventor based in Kawasaki, Japan, has made significant contributions to the field of resist technology, amassing a total of 38 patents throughout his career. His work primarily focuses on developing resist compositions and methods for forming resist patterns critical to modern semiconductor manufacturing.
Latest Patents
Among his latest patents is a groundbreaking resist composition and method of forming a resist pattern. The resist composition comprises a silicon-containing resin, an acid generator, and a photodecomposable base to control the diffusion of the generated acid. The silicon content in the resin is maintained between 20% to 25% relative to the total atomic composition. The method of forming a resist pattern involves creating a resist film which exhibits increased solubility in an alkali developing solution. This process includes exposing and baking the resist film to neutralize the base generated from the photo-base generator while enhancing the solubility of unexposed portions, ultimately resulting in a negative-tone resist pattern.
