Title: Innovations by James Chiang
Introduction
James Chiang is a notable inventor based in Mountain View, CA (US). He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work primarily focuses on methods that enhance the performance and efficiency of transistors.
Latest Patents
One of his latest patents is titled "Method of fabricating ultra shallow junction CMOS transistors with nitride disposable spacer." This innovative method involves developing a complimentary MOS (CMOS) transistor that includes lightly doped drain (LDD) regions using disposable spacers. The process incorporates an additional step of adding an oxide spacer etch after the removal of the disposable nitride spacer, which allows for an ultra shallow LDD implant. This advancement improves the uniformity of the junction depth by eliminating the non-uniformity of the screen/liner oxide.
Another significant patent by Chiang is the "Method for amorphous silicon local interconnect etch." In this process, a silicon layer is etched using a plasma etcher equipped with an endpoint control device. The etcher utilizes CF and N at lower flow rates than those typically employed in fixed time etching processes. The endpoint control device monitors optical emissions from the etching chamber at a specific wavelength to detect a predetermined change in intensity, terminating the etching process when this change is observed.
