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 38):
A method of fabricating an integrated circuit, the method comprising:\n forming a pair n+ doped III-N semiconductor drains over two adjacent substrate regions; epitaxially growing an n\u2212 doped III-N semiconductor drift region from each of the pair of drains, the growing confined to within a trench in an amorphous layer that is over a portion of the drains; epitaxially growing a pair of III-N semiconductor bodies from a surface of the n\u2212 doped III-N semiconductor with growth conditions that expand the III-N semiconductor islands laterally over a top surface of the amorphous layer; forming a pair of gate electrodes, over a channel portion of the III-N semiconductor bodies; and forming drain contact metallization through the amorphous layer and contacting both of the pair of III-N drains.
