    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： Provided is a power amplifier including: a depletion mode high electron mobility transistor (D-mode HEMT) configured to amplify a signal inputted to a gate terminal and output the amplified signal through a drain terminal; an input matching circuit configured to serially ground the gate terminal; and a DC bias circuit connected between the drain terminal and a ground. Through the foregoing configuration, the HEMT may be biased only by a single DC bias circuit without any biasing means to provide a negative voltage. Also, superior matching characteristic may be provided in various operation frequency bands through a shunt inductor and a choke inductor.
