    摘要: Disclosed are a semiconductor device and a method of manufacturing the same. In the semiconductor device according to an exemplary embodiment of the present disclosure, at the time of forming a source electrode, a drain electrode, a field plate electrode, and a gate electrode on a substrate having a heterojunction structure such as AlGaN/GaN, the field plate electrode made of the same metal as the gate electrode is formed on the side surface of a second support part positioned below a head part of the gate electrode so as to prevent the gate electrode from collapsing and improve high-frequency and high-voltage characteristic of the semiconductor device.

    摘要: A method of fabricating a T-gate is provided. The method includes the steps of: forming a photoresist layer on a substrate; patterning the photoresist layer formed on the substrate and forming a first opening; forming a first insulating layer on the photoresist layer and the substrate; removing the first insulating layer and forming a second opening to expose the substrate; forming a second insulating layer on the first insulating layer; removing the second insulating layer and forming a third opening to expose the substrate; forming a metal layer on the second insulating layer on which the photoresist layer and the third opening are formed; and removing the metal layer formed on the photoresist layer. Accordingly, a uniform and elaborate opening defining the length of a gate may be formed by deposition of the insulating layer and a blanket dry etching process, and thus a more elaborate micro T-gate electrode may be fabricated.
