Title: Charles Chu: Innovator in Transistor Technology

Introduction

Charles Chu is a notable inventor based in Portland, OR (US). He has made significant contributions to the field of semiconductor technology, particularly in the development of advanced transistors. With a total of 2 patents to his name, Chu's work has had a considerable impact on the performance of electronic devices.

Latest Patents

One of his latest patents is for a "Transistor with Notched Gate." This invention features a transistor that has a gate electrode with a T-shaped cross section, fabricated from a single layer of conductive material using an etching process. A two-process etch is performed to create side walls with a notched profile. The notches facilitate the implantation of source and drain regions into a substrate, allowing for thermal processing without generating excessive overlap capacitance with the gate electrode. This reduction in overlap capacitance enhances the transistor's operating performance, including drive current.

Another significant patent is the "Method for Making MOS Transistors." This improved method involves forming a polysilicon layer on a silicon dioxide layer, which is then placed on a substrate. After etching the polysilicon and silicon dioxide layers to define a gate electrode and a gate oxide, dopants are implanted into the substrate. Following this implantation step, the exposed portion of the gate oxide is cleaned and sealed, ensuring the integrity of the transistor.
