Introduction

Sahwan Hong is a prominent inventor based in Suwon-si, South Korea. He has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. His work focuses on advanced methods for pattern formation and integrated circuit devices.

Latest Patents

One of his latest patents is a pattern formation method and semiconductor device fabrication method. This method includes forming a first capping layer on a substrate and creating a recess that penetrates the first capping layer and an upper portion of the substrate. The non-penetrated portion of the first capping layer constitutes a first capping pattern. Additionally, a second capping pattern is formed to cover the inner sidewall of the recess, and a stack structure is created within the recess, consisting of first and second stack patterns that are alternately stacked. The second capping pattern is positioned between the substrate and a lateral surface of the stack structure.

Another notable patent involves integrated circuit devices that include vertically stacked field effect transistors. This integrated circuit device features an active region extending in a first horizontal direction on a substrate. It includes a first transistor at a first vertical level on the active region, which has a first source/drain region of a first conductive type. A second transistor is positioned at a higher vertical level on the active region, with a second source/drain region of a second conductive type that overlaps the first source/drain region in a vertical direction. The first and second source/drain regions differ in size.
