Title: Ji-hwan Choi: Innovator in Semiconductor Technology
Introduction
Ji-hwan Choi 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
Ji-hwan Choi'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 design ensures 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 further elaborates on the same semiconductor device and its manufacturing method, emphasizing the innovative techniques employed in the etching process.
