Title: The Innovations of Shozo Miyazawa
Introduction
Shozo Miyazawa is a notable inventor based in Chigasaki, Japan. He has made significant contributions to the field of photosensitive resin compositions, holding a total of 3 patents. His work has been instrumental in advancing technologies used in photolithography and related applications.
Latest Patents
Miyazawa's latest patents include a water-soluble photosensitive resin composition and a method of forming it. This improved composition features a high-polymer compound and a water-soluble polymer, which can be polyvinylpyrrolidone or a copolymer of vinylpyrrolidone and vinylimidazole. The composition is designed for application to substrates, where it is exposed through a mask pattern and developed to create a photocured pattern. This innovative approach allows for efficient formation of photocured patterns with high sensitivity, using shorter exposure times and lower intensities. Additionally, the composition adheres strongly to glass substrates, ensuring faithful pattern formation.
Another significant patent involves an undercoating material for photosensitive resins. This undercoating composition is derived from a condensation product of a hydroxy-substituted diphenylamine and a melamine compound. The resulting undercoating layer is highly resistant to overcoating solutions, greatly improving the fidelity of pattern reproduction in photolithographic techniques.
