Title: Innovations of Charles C Yang
Introduction
Charles C Yang is a notable inventor based in Gilbert, AZ (US). He has made significant contributions to the field of semiconductor technology, particularly in the development of silicon wafers. With a total of 3 patents to his name, Yang's work has had a considerable impact on the industry.
Latest Patents
Yang's latest patents include innovations related to epitaxial silicon wafers with intrinsic gettering. One of his inventions describes a wafer characterized by a non-uniform distribution of crystal lattice vacancies. In this design, the concentration of crystal lattice vacancies in the bulk layer is greater than that in the front surface layer. The front surface of the wafer features an epitaxial layer with a thickness of less than about 2.0 μm. The process involves heating the surface of a wafer starting material to remove a silicon oxide layer and depositing an epitaxial layer onto the surface. This results in an epitaxial wafer that is heated to a soak temperature of at least about 1175°C while being exposed to an oxidizing atmosphere.
Another patent focuses on a single crystal silicon wafer that includes two major generally parallel surfaces and a central plane. This wafer is characterized by a non-uniform distribution of crystal lattice vacancies, with a peak density at or near the central plane. The concentration of crystal lattice vacancies decreases from the peak density toward the front surface of the wafer, enhancing its performance in various applications.
