Title: Innovations of Chun-Hung Chu

Introduction

Chun-Hung Chu is a notable inventor based in Fengyuan, Taiwan. He has made significant contributions to the field of thin film transistor liquid crystal displays (TFT-LCD). With a total of 4 patents to his name, his work has advanced the technology used in modern display systems.

Latest Patents

Chun-Hung Chu's latest patents include a thin film transistor array substrate. This invention provides a substrate for TFT-LCDs that features a gate dielectric layer composed of a silicon nitride layer, a dielectric layer, and another silicon nitride layer. The etching selectivity of the amorphous silicon layer over the dielectric layer is designed to be no less than about 5.0. This innovation allows for better control of the dielectric layer thickness, which in turn helps manage the capacitance of the storage capacitor.

Another significant patent is a method of controlling the capacitance of a TFT-LCD storage capacitor. This method involves forming a silicon island and a bottom electrode on a transparent substrate. The silicon island has an undoped region at its center and two doped regions on either side. A first silicon nitride layer is then formed on the substrate, followed by a stacked layer that includes a second silicon nitride layer and a conductive layer. The first conductive layer serves as the gate of the thin film transistor, with an etching selectivity ratio of the conductive layer over the dielectric layer also being no less than about 5.0.
