  • Patent number: 10461159
    Abstract: Characteristics of a semiconductor device using a nitride semiconductor are improved. A semiconductor device of the present invention includes a buffer layer, a channel layer, a barrier layer, a mesa-type 2DEG dissolving layer, a source electrode, a drain electrode, a gate insulating film formed on the mesa-type 2DEG dissolving layer, and an overlying gate electrode. The gate insulating film of the semiconductor device includes a sputtered film formed on the mesa-type 2DEG dissolving layer and a CVD film formed on the sputtered film. The sputtered film is formed in a non-oxidizing atmosphere by a sputtering process using a target including an insulator. This makes it possible to reduce positive charge amount at a MOS interface and in gate insulating film and increase a threshold voltage, and thus improve normally-off characteristics.

  • Patent number: 10249715
    Abstract: Properties of a semiconductor device are improved. A semiconductor device is configured so as to include a voltage clamp layer, a channel underlayer, a channel layer, and a barrier layer, which are formed in order above a substrate, a trench that extends up to the middle of the channel layer while penetrating through the barrier layer, a gate electrode disposed within the trench with a gate insulating film in between, a source electrode and a drain electrode formed above the barrier layer on both sides of the gate electrode, and a fourth electrode electrically coupled to the voltage clamp layer. The fourth electrode is electrically isolated from the source electrode, and a voltage applied to the fourth electrode is different from a voltage applied to the source electrode. Consequently, threshold control can be performed. For example, a threshold of a MISFET can be increased.
