Title: **Innovator Jiann-Kwang Wang: Advancements in CMP Processes**
Introduction
Jiann-Kwang Wang, an esteemed inventor based in Hsin-Chu, Taiwan, has made significant contributions to the field of semiconductor manufacturing. With a robust portfolio that includes five patents, Wang's work has influenced industry practices, particularly in chemical mechanical polishing (CMP) processes.
Latest Patents
One of Jiann-Kwang Wang's notable innovations addresses two prevalent issues in traditional CMP: the retention of slurry particles on the polished surface and the formation of residual oxide layers. His innovative approach involves the addition of TMAH or TBAH to the slurry, which enhances the hydrophobic properties of the surface being polished. This improvement ensures that no residual layers of oxide remain after CMP, and minimal slurry abrasive particles cling to the freshly polished surface. Furthermore, these remaining particles can be easily removed with a simple rinse or buffing technique. Alternatively, Wang has proposed a three-stage CMP process that includes conventional CMP, polishing in a solution of TMAH or TBAH, followed by a gentle rinse or buffing.
