Title: Ki-Hong Yang: Innovator in Semiconductor Fabrication
Introduction
Ki-Hong Yang is a prominent inventor based in Seongnam-si, South Korea. He has made significant contributions to the field of semiconductor device fabrication. With a total of 3 patents to his name, Yang continues to push the boundaries of technology and innovation.
Latest Patents
One of his latest patents is a method for fabricating a semiconductor device. This method includes forming a through-hole that penetrates through an alternating stack pattern and creating a gap-fill layer. A sacrificial gap-fill layer of the gap-fill layer fills the through-hole. The process also involves forming a mask layer over the alternating stack pattern and the gap-fill layer. This mask layer features a self-aligned opening that overlaps the filled through-hole and a portion of the uppermost material layer of the alternating stack pattern adjacent to the filled through-hole. Furthermore, the method includes forming a first contact hole through the alternating stack pattern by performing a single etch. This etch uses both the mask layer and the portion of the uppermost material layer as etch barriers to remove the sacrificial gap-fill layer filling the through-hole through the self-aligned opening.
