Title: The Innovations of James R. Shealy
Introduction
James R. Shealy is a prominent inventor based in Ithaca, NY, known for his significant contributions to semiconductor technology. With a total of 17 patents to his name, Shealy has made remarkable advancements in the field of high voltage field effect transistors and light-emitting diodes.
Latest Patents
One of his latest patents is a method for implanting and annealing high voltage field effect transistors. This invention provides a method of forming a semiconductor device on a gallium and nitrogen-containing material. The process includes providing a substrate member with a surface region made of gallium and nitrogen-bearing material. It also involves causing an implanted species to electrically activate the implant profile while removing crystalline damage from the epitaxial material, transforming the amorphous state into a single crystalline state. This results in a substantially electrically activated crystalline material.
Another notable patent is for a beryllium-doped GaN-based light-emitting diode and method. This invention offers a method and apparatus to incorporate beryllium followed by activation to create p-type materials with lower resistivity than magnesium. The higher hole concentrations achieved through this method lead to lower contact resistances and more effective electron confinement. Consequently, this results in a higher efficiency GaN-based LED with enhanced current handling capability, producing a brighter device of the same area.
