Title: Yeo-cheol Yoon: Innovator in Semiconductor Technology

Introduction

Yeo-cheol Yoon is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of semiconductor technology, holding two patents that showcase his innovative approach to manufacturing semiconductor devices.

Latest Patents

Yeo-cheol Yoon's latest patents include methods of manufacturing semiconductor devices that feature chamfered silicide layers. The first patent describes a semiconductor device that includes a first insulation layer overlying a semiconductor substrate, along with gate structures that consist of first conductive layer patterns and second conductive layer patterns. The unique aspect of this design is that the lower sides of the second conductive layer patterns are substantially perpendicular to the major surface of the semiconductor substrate, while the upper sides are chamfered. The manufacturing process involves isotropic dry etching to form undercut regions that define the chamfered upper edges of the metal silicide layer patterns. This process can be performed simultaneously with the ashing of photoresist patterns or immediately after in the same chamber.

The second patent also focuses on a semiconductor device with a chamfered silicide layer and outlines a similar manufacturing method. The detailed description emphasizes the importance of the insulation layers and the etching processes involved in achieving the desired structural characteristics of the semiconductor device.
