Abstract

See full text

The present disclosure relates to a high electron mobility transistor compatible power lateral field-effect rectifier device. In some embodiments, the rectifier device has an electron supply layer located over a layer of semiconductor material at a position between an anode terminal and a cathode terminal. A layer of doped III-N semiconductor material is disposed over the electron supply layer. A layer of gate isolation material is located over the layer of doped III-N semiconductor material. A gate structure is disposed over layer of gate isolation material, such that the gate structure is separated from the electron supply layer by the layer of gate isolation material and the layer of doped III-N semiconductor material. The layer of doped III-N semiconductor material modulates the threshold voltage of the rectifier device, while the layer of gate isolation material provides a barrier that gives the rectifier device a low leakage.
