Title: Dongxu Yang: Innovator in Photoresist Compositions
Introduction
Dongxu Yang is a prominent inventor based in Birmingham, GB. He has made significant contributions to the field of photoresist compositions, holding a total of 8 patents. His innovative work focuses on enhancing the resolution and exposure latitude in fine pattern processing.
Latest Patents
Yang's latest patents include groundbreaking developments in multiple trigger monomer containing photoresist compositions and methods. These patents describe novel negative working photoresist compositions that involve a two-step process. The first step entails removing acid-labile protecting groups from crosslinking functionalities, while the second step involves crosslinking these functionalities with an acid-sensitive crosslinker. This innovative approach increases the chemical gradient in areas receiving a low dose of irradiation, effectively acting as a built-in dose-dependent quencher-analog. As a result, it enhances the chemical gradient, resolution, resolution blur, and exposure latitude. The photoresist compositions are ideal for fine pattern processing using various radiation types, including ultraviolet radiation, extreme ultraviolet radiation, X-rays, and charged particle rays.
