Title: Yusuke Anno: Innovator in Pattern-Forming Technologies

Introduction

Yusuke Anno, an accomplished inventor based in Tokyo, Japan, has made significant contributions to the field of pattern-forming technologies. With eight patents to his name, Anno is recognized for his innovative approaches that enhance the efficiency and effectiveness of resist patterns used in various applications.

Latest Patents

Among Anno's latest inventions is a "Pattern-forming method and composition for resist pattern-refinement." This method involves the creation of a prepattern that remains insoluble or has minimal solubility in organic solvents. By applying a first composition to the prepattern's lateral faces, a resin layer is formed. This process allows adjacent regions of the resin layer to become insolubilized or desolubilized without increasing molecular weight through heating. The innovative features of his first composition, which includes a polymer with a unique solubility response to acid, highlight the technical sophistication of his work.

Another notable patent is the "Resist pattern-forming method," which details the application of a resist underlayer film-forming composition that includes a polysiloxane. This composition is further enhanced by a radiation-sensitive resin that alters its polarity when exposed to acid, demonstrating Anno’s deep understanding of chemical interactions and material science.
