    摘要: Power switching circuits including an inductive load and a switching device are described. The switches devices can be either low-side or high-side switches. Some of the switches are transistors that are able to block voltages or prevent substantial current from flowing through the transistor when voltage is applied across the transistor.

    摘要: A transistor device is described that includes a source, a gate, a drain, a semiconductor material which includes a gate region between the source and the drain, a plurality of channel access regions in the semiconductor material on either side of the gate, a channel in the semiconductor material having an effective width in the gate region and in the channel access regions, and an isolation region in the gate region. The isolation region serves to reduce the effective width of the channel in the gate region without substantially reducing the effective width of the channel in the access regions. Alternatively, the isolation region can be configured to collect holes that are generated in the transistor device. The isolation region may simultaneously achieve both of these functions.

    摘要: A III-N semiconductor HEMT device includes an electrode-defining layer on a III-N material structure. The electrode-defining layer has a recess with a first sidewall proximal to the drain and a second sidewall proximal to the source, each sidewall comprising a plurality of steps. A portion of the recess distal from the III-N material structure has a larger width than a portion of the recess proximal to the III-N material structure. An electrode is in the recess, the electrode including an extending portion over the first sidewall. A portion of the electrode-defining layer is between the extending portion and the III-N material structure. The first sidewall forms a first effective angle relative to the surface of the III-N material structure and the second sidewall forms a second effective angle relative to the surface of the III-N material structure, the second effective angle being larger than the first effective angle.

    摘要: A diode is described with a III-N material structure, an electrically conductive channel in the III-N material structure, two terminals, wherein a first terminal is an anode adjacent to the III-N material structure and a second terminal is a cathode in ohmic contact with the electrically conductive channel, and a dielectric layer over at least a portion of the anode. The anode comprises a first metal layer adjacent to the III-N material structure, a second metal layer, and an intermediary electrically conductive structure between the first metal layer and the second metal layer. The intermediary electrically conductive structure reduces a shift in an on-voltage or reduces a shift in reverse bias current of the diode resulting from the inclusion of the dielectric layer. The diode can be a high voltage device and can have low reverse bias currents.

    摘要: Transistor devices which include semiconductor layers with integrated hole collector regions are described. The hole collector regions are configured to collect holes generated in the transistor device during operation and transport them away from the active regions of the device. The hole collector regions can be electrically connected or coupled to the source, the drain, or a field plate of the device. The hole collector regions can be doped, for example p-type or nominally p-type, and can be capable of conducting holes but not electrons.
