Title: Hyuk-Ju Ryu: Innovator in Semiconductor Technology
Introduction
Hyuk-Ju Ryu is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. His work focuses on improving the efficiency and performance of CMOS devices.
Latest Patents
One of his latest patents is titled "CMOS transistor having different PMOS and NMOS gate electrode structures and method of fabrication thereof." This invention involves a CMOS semiconductor device that utilizes a silicon germanium gate. The method includes forming a gate insulating layer, a conductive electrode layer, a silicon germanium electrode layer, and an amorphous conductive electrode layer on a semiconductor substrate. A photolithographic process is then employed to selectively remove the silicon germanium electrode layer in the NMOS region, ensuring that it is only present in the PMOS region.
Another notable patent is the "Method of manufacturing a semiconductor device having a gate structure with low parasitic capacitance." This method outlines the sequential formation of a gate insulation layer and a gate electrode on a substrate. A planarized layer is created on the substrate, which is then partially removed to expose the upper portion of the gate electrode. A silicon epitaxial layer is selectively formed on the exposed gate electrode, stabilizing gate resistance and reducing parasitic capacitance between the gate electrode and the source/drain region.
