Chia-Hui Wu is a notable inventor based in Kaohsiung, Taiwan. He has made significant contributions to the field of semiconductor technology. His innovative approach has led to the development of a unique method that addresses challenges in chemical mechanical polishing (CMP).

Latest Patents

Chia-Hui Wu holds a patent for a method to prevent CMP overpolish. This process is designed to avoid dishing in a planarizing layer whose final thickness is reduced by chemical mechanical polishing. The method involves coating the surface to be planarized with a layer of a hard dielectric material, such as silicon nitride, before depositing the planarizing medium. After the medium has been reflowed, its thickness is reduced through CMP. During the CMP process, the etch rate is continuously monitored. When the etch front approaches the hard layer, a decrease in the etch rate is detected, prompting the termination of etching to eliminate any dishing effects. This innovative solution enhances the efficiency and quality of semiconductor manufacturing.
