Title: **Guo-Qiang (Patrick) Lo: Innovator in Semiconductor Technology**

Introduction

Guo-Qiang (Patrick) Lo is an accomplished inventor based in Portland, OR, with a notable record of six patents to his name. His contributions to the field of semiconductor technology have made significant impacts in the industry, particularly through innovative approaches to stress-relieved shallow trench isolation structures.

Latest Patents

Among his latest innovations, Patrick Lo has developed patented technology for a stress-relieved shallow trench isolation (STI) structure and a method for forming the same. This technology involves creating a trench in a semiconductor substrate, where a first dielectric layer is formed on the trench's sidewalls. The innovation lies in the first dielectric layer being thicker at the top portion of the sidewalls compared to the bottom, allowing the trench entrance to remain open. A second conformal dielectric layer is then applied to close the entrance, which results in a void being buried within the trench. This design effectively reduces the stress that occurs between the trench dielectric layer and the surrounding silicon substrate during thermal cycling, enhancing the performance and reliability of semiconductor devices.
