Latest Patents
One of his latest patents is titled "Method for making self-aligned ohmic contacts." This invention describes a method for creating a semiconductor device with self-aligned ohmic contacts that significantly reduces shadowing. The process involves covering the gate material with a layer of gate mask material, which is selectively removed to form a gate mask with sidewalls designed to avoid maximum shadow encroachment during subsequent material depositions. The gate mask material is characterized by sidewalls that have an angularity sufficient to accommodate the angle of evaporative deposition of ohmic contact material.
Another significant patent is the "Method of manufacturing self-aligned GaAs MESFET." This patent outlines the formation of a self-aligned MESFET by implanting a channel region in a gallium arsenide substrate. A dielectric layer is formed on the substrate, and portions of this layer are selectively removed to create a substitutional gate mesa. The process includes forming sidewall spacers and implanting ions into the substrate to create source and drain regions, followed by annealing and the formation of a conductive gate layer.
