Title: Innovations of Jin-Yul Lee in Semiconductor Technology

Introduction

Jin-Yul Lee is a prominent inventor based in Gyeonggi-do, South Korea. He has made significant contributions to the field of semiconductor technology, holding a total of 15 patents. His work focuses on innovative methods for manufacturing semiconductor devices, which are crucial for modern electronics.

Latest Patents

Among his latest patents, Jin-Yul Lee has developed an isolation structure and a method for manufacturing the same. This method involves forming a first trench and a second trench in a substrate, where the two trenches communicate with each other. The second trench is designed to be wider than the first trench. The process includes forming a liner layer over the inner surfaces of both trenches, followed by a capping layer that creates merged and non-merged overhangs. The merged overhang fills the top portion of the first trench, while the non-merged overhang leaves the top portion of the second trench open. Finally, a gap-fill layer is formed over the capping layer to fill the lower portions of both trenches.

Another notable patent by Jin-Yul Lee is a method of manufacturing an isolation structure for semiconductor devices. This method shares similarities with his previous patent, emphasizing the importance of trench formation and the layering process in semiconductor manufacturing.
