Title: Wei Kai Hong: Innovator in Field Emission Technology
Introduction
Wei Kai Hong is a notable inventor based in Yung-Ho, Taiwan. He has made significant contributions to the field of field emission technology, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents is titled "Process for forming a film on a substrate having a field emitter." This patent discloses a method where the substrate and field emitter are cleaned using hydrogen plasma to eliminate impurities. Following this, a silicon carbide film is selectively formed over the field emitter. A negative bias voltage ranging from about 150 V to about 300 V is applied to the substrate to enhance the nucleation sites of the silicon carbide film. Once this is achieved, the negative bias voltage is halted to allow for the growth of a carbon-containing film from the silicon carbide film.
Another significant patent is the "Method of fabricating a field emission device on the sidewalls of holes formed in an insulator layer." This invention describes a process where a conductive layer is etched back using a reactive ion etching (RIE) process to create a chimney-shaped structure, either diode-type or triode-type, which serves as a field emitter. This field emission device can be manufactured at temperatures below 400°C, without the need for complex techniques or equipment, making it suitable for application in large-area flat panel displays.
