A III-nitride transistor includes a III-nitride channel layer, a barrier layer over the channel layer, the barrier layer having a thickness of 1 to 10 nanometers, a dielectric layer on top of the barrier layer, a source electrode contacting the channel layer, a drain electrode contacting the channel layer, a gate trench extending through the dielectric layer and barrier layer and having a bottom located within the channel layer, a gate insulator lining the gate trench and extending over the dielectric layer, and a gate electrode in the gate trench and extending partially toward the source and the drain electrodes to form an integrated gate field-plate, wherein a distance between an interface of the channel layer and the barrier layer and the bottom of the gate trench is greater than 0 nm and less than or equal to 5 nm. |
