Title: Paichun Chang and Film-Formation Innovation.
Introduction
Paichun Chang is an inventor associated with Taoyuan, Taiwan. His patent work includes a method for forming a polymer film on a workpiece through controlled deposition and sublimation.
Latest Patents
Chang is credited with 1 patent, titled “Method for Forming Film.” The method controls the workpiece temperature so a gaseous sacrificial material desublimates onto its surface, forming a solid layer. As the layer gradually sublimates under controlled chamber pressure and temperature, reactive polymer monomers are introduced and adsorb onto it, initiating polymerization. The sacrificial material eventually sublimates completely, leaving a polymer layer deposited on the workpiece.
Career Highlights
Chang is associated with Tripod Technology Corporation. His patented method describes a process for forming polymer films by coordinating sacrificial-material phase changes with monomer adsorption and polymerization.
Collaborations
Yu-Ming Chang and Yun-Shan Wang are identified as Chang’s coworkers. The available information does not specify their roles in the patent or the invention.
Conclusion
Paichun Chang’s patent presents a controlled film-formation process that uses sublimation and polymerization to create a polymer layer on a workpiece.
