Title: Hyung-seok Hong and Semiconductor Device Innovation.

Introduction

Hyung-seok Hong is an inventor based in Seoul, South Korea, whose patent work includes semiconductor fabrication. He is associated with Samsung Electronics Co., Ltd. and is credited with 12 patents.

Latest Patents

One of Hong’s latest listed inventions is “Method of Fabricating Semiconductor Device Having Dual Gate.” The patent describes a fabrication process designed to enable different threshold voltages in two regions of a semiconductor device.

The method forms a gate insulation layer, a first capping layer, and a barrier layer across both regions. After removing the first capping and barrier layers from the first region, a second capping layer is formed over the exposed gate insulation layer and the barrier layer in the second region. Thermal processing then causes material from the capping layers to spread into the gate insulation layer in their respective regions, supporting devices with different threshold voltages.

Career Highlights

Hong’s listed patent portfolio reflects work in semiconductor-device manufacturing, particularly processes for tailoring transistor characteristics through material layers and thermal treatment. His affiliation with Samsung Electronics connects this work to a company active in electronics and semiconductor technologies.
