Title: Nitride semiconductor device
Inventor: UENO KATSUNORI
IPC: H01L27/04
Filed: 2011-04-22
Abstract: PROBLEM TO BE SOLVED: To provide a nitride semiconductor device that prevents breakdown of a gate insulating film of a MOS-type device and improves reliability.SOLUTION: An SBD metal electrode 30 provided between a drain electrode 26 and a gate electrode 28 is Schottky-joined to an AlGaN layer 20. Additionally, the SBD metal electrode 30 and a source electrode 24 are connected, being electrically shorted. For this reason, when an off signal is applied to the gate electrode 28, a MOSFET section 32 becomes an off state, so that a drain-side voltage of the MOSFET section 32 becomes close to a voltage value of the drain electrode 26. When the voltage of the drain electrode 26 increases, the drain side of the MOSFET section 32 and the drain electrode 26 are electrically disconnected by the SBD metal electrode 30, because the voltage value of the SBD metal electrode 30 is lower than the voltage value of the drain side of the MOSFET section 32.
