Latest Patents

Among his latest patents, Lothian has introduced a novel **Method of Forming a T-Shaped Gate**. This invention details innovative techniques for creating T-shaped metal gates for Schottky gate devices, including MESFETs and HEMTs. The method employs a bi-level photoresist technique to achieve a precise T-shaped feature in the gate structure. By evaporating metal into the photoresist and utilizing a lift-off process, unwanted metal is effectively removed, culminating in the formation of the T-shaped gate. A notable aspect of his work is the plasma treatment of the first patterned resist level, which fortifies the material against subsequent deposition processes.

Another significant contribution by Lothian is the article titled **Comprising an Oxide Layer on GaN**. In this patent, a high-quality oxide layer is formed on a GaN surface through meticulous preparation of the material. By ensuring that the surface is atomically clean and ordered, and exposing it to evaporant from a gallium gadolinium garnet (GGG) evaporation source, Lothian has enabled the development of MOS structures that demonstrate low leakage current, alongside effective charge accumulation and depletion.
