Title: Arthur E Geissberger: A Pioneer in Semiconductor Innovations
Introduction
Arthur E Geissberger is a notable inventor based in Roanoke, Virginia, who has made significant contributions to the field of semiconductor technology. With a portfolio of 10 patents to his name, Geissberger has played a pivotal role in advancing the design and performance of field-effect transistors (FETs), particularly in the realm of gallium arsenide (GaAs) technology.
Latest Patents
Among his latest inventions are two groundbreaking patents. The first, titled "Heterojunction Confined Channel FET," introduces a new GaAs FET structure. This innovative process creates a GaAs channel sandwiched between AlGaAs layers, enhancing the active carrier concentration of the GaAs channel compared to its adjacent layers. The second patent, "Self-Aligned Gate Realignment Employing Planarizing Overetch," details a methodology for manufacturing self-aligned gate (SAG) transistors or FETs. This method allows for considerable alignment tolerances during production, reduces gate resistance through the inclusion of a second highly conductive layer of gate metallization, and avoids performance degradation due to misalignment.
