Introduction

Shing-Gong Liu is a prominent inventor based in Princeton, NJ, known for his significant contributions to semiconductor technology. With a total of seven patents to his name, Liu has made remarkable advancements in the field, particularly in the development of ohmic contacts and methods for enhancing electron mobility.

Latest Patents

One of Liu's latest patents is titled "Ohmic contact and method for making same." This invention describes an ohmic contact to a semiconductor body that includes a thin semiconductor layer positioned between the body and a conductive layer. The thin layer is not alloyed to the conductive layer and is not lattice matched to the body, allowing for a thickness of less than about 100 nm and a lattice mismatch of at least 0.5 percent. This innovative approach enables the formation of a Schottky contact simultaneously with the ohmic contact. Another notable patent is "Method for enhancing electron mobility in GaAs." This method enhances the electron mobility in an active layer on a semi-insulating substrate by initially performing a high-energy implantation of an inert element in the semi-insulating material. Following this, donor ions are implanted to form the active layer in the area where the high-energy implantation was conducted, and the substrate is subsequently annealed.
