Gallium nitride material devices including an electrode-defining layer and methods of forming the same

摘要

Gallium nitride material devices and methods of forming the same are provided. The devices include an electrode-defining layer. The electrode-defining layer typically has a via formed therein in which an electrode is formed (at least in part). Thus, the via defines (at least in part) dimensions of the electrode. In some cases, the electrode-defining layer is a passivating layer that is formed on a gallium nitride material region.
