Abstract:
III-N transistor including a vertically-oriented lightly-doped III-N drift region between an overlying III-N 2DEG channel and an underlying heavily-doped III-N drain. In some embodiments, the III-N transistors are disposed over a silicon substrate. In some embodiments, lateral epitaxial overgrowth is employed to form III-N islands self-aligned with the vertically-oriented drift region. A gate electrode disposed over a portion of a III-N island may modulate a 2DEG within a channel region of the III-N island disposed above the III-N drift region. Charge carriers in the 2DEG channel may be swept into the drift region toward the drain. Topside contacts to each of the gate, source, and drain may be pitch scaled independently of a length of the drift region.

Claim (Index 29):
An integrated circuit (IC), comprising:\n a pair of III-N transistors over a silicon substrate, each transistor further comprising:\n a gate electrode over a channel region, the channel region comprising a Group III element and nitrogen; \n a source coupled to the channel region on either side of the gate electrode, the source comprising a Group III element, nitrogen, and a donor impurity having at least a first concentration; \n a drain coupled to the channel region and opposite the gate electrode, wherein the drain is coupled to channel region through a drift region comprising a Group III element, nitrogen, and a donor impurity having a second concentration, less than the first concentration; and \n a drain contact between a source of a first of the transistors and a source of a second of the transistors, wherein the drain contact is coupled to a drain of each of the transistors.
