Title: **The Innovative Mind of Yao Fong Dai**

Introduction

Yao Fong Dai is a prominent inventor based in Hsinchu, Taiwan, who has made significant contributions to the field of chemical vapor deposition (CVD). With three patents to his name, Dai is recognized for his innovative approach and methodologies that enhance manufacturing processes in the semiconductor industry.

Latest Patents

Dai's latest inventions center around improving CVD techniques. One of his notable patents involves a CVD apparatus featuring multi-zone thickness control. This invention outlines a method where a process gas is introduced into a vacuum chamber and redistributed through a specially designed shower head. The process gas exhibits a density increase from the center to the peripheral regions of the chamber, which results in the formation of a precursor material with an uneven thickness profile due to the gas's non-uniform distribution.

Another patent by Dai details a CVD apparatus that aims to enhance the planarity of layered materials post-chemical-mechanical polishing (CMP). This apparatus also uses a vacuum chamber with strategically located gas import and exhaust ports, alongside a multi-holed shower head to improve the CVD process. Together, these innovations significantly further semiconductor manufacturing techniques.
