Title: Yu-Ming Chang: Inventor in Film-Formation Technology.
Introduction
Yu-Ming Chang is an inventor based in Taoyuan, Taiwan. His patent work includes a method for forming a polymer film on a workpiece, and he is associated with Tripod Technology Corporation.
Latest Patents
Chang is credited with 1 patent, titled “Method for Forming Film.” The method controls the temperature of a workpiece so that a gaseous sacrificial material desublimates onto its surface, forming a solid layer. The chamber pressure and workpiece temperature are then adjusted to make the layer gradually sublime. Reactive polymer monomers are introduced and adsorb onto the sacrificial layer, initiating polymerization as the layer continues to sublime. Once the sacrificial material has fully sublimated, a polymer layer remains deposited on the workpiece surface.
Career Highlights
Chang’s listed patent reflects work on a film-formation process that combines sacrificial-material sublimation with monomer adsorption and polymerization. He is associated with Tripod Technology Corporation.
Collaborations
Chang’s listed coworkers include Yun-Shan Wang and Hsien-Yeh Chen.
Conclusion
Yu-Ming Chang’s patent describes a process for forming a polymer film through controlled sublimation and polymerization, highlighting his contribution to film-formation technology.
