Title: The Innovative Mind of Ching-Ping Wu

Introduction

Ching-Ping Wu, an inventive force hailing from Hsin-Chu, Taiwan, has made significant contributions to the field of semiconductor technology. With two patents to his name, Wu has demonstrated an exceptional ability to innovate practical solutions for the challenges faced in wafer processing and storage.

Latest Patents

Among his latest patents is a groundbreaking invention titled "Wafer shipping device and storage method for preventing fluoridation in bonding pads." This invention encompasses a novel shipping box designed to safeguard bonding pads from fluoridation. The process begins with drilling at least one through hole in the shipping box, whereupon the wafer is placed inside. It is then subjected to a vacuum packaging process, effectively removing air and introducing dry inert gas to maintain structural integrity. Once atmospheric pressure is reached, the packaging bag is sealed, ensuring the protection of the contents.

Another noteworthy patent is the "Method of removing HDP oxide deposition." This method involves a two-step etching process: first, using an inside-out model, where etching occurs at a faster rate in the center than at the edges, followed by an outside-in model that reverses this rate. This technique culminates in the removal of any remaining silicon oxide layer through chemical-mechanical polishing (CMP). This method enhances uniformity in planarization, addressing a critical issue in the manufacturing process.
