ION IMPLANTED AND SELF ALIGNED GATE STRUCTURE FOR GAN TRANSISTORS

摘要

A self-aligned transistor gate structure that includes an ion-implanted portion of gate material surrounded by non-implanted gate material on each side. The gate structure may be formed, for example, by applying a layer of GaN material over an AlGaN barrier layer and implanting a portion of the GaN layer to create the gate structure that is laterally surrounded by the GaN layer.
