Abstract:
A vertical JFET is provided. The JFET is mixed with lateral channel structure and p-GaN gate structure. The JFET has a N+ implant source region. In one embodiment, a JFET is provided with a drain metal deposited over a backside of an N substrate, an n-type drift layer epitaxial grown over a topside of the N substrate, a buried P-type block layer deposited over the n-type drift layer, an implanted N+ source region on side walls of the lateral channel layer, and an source metal attached to the top of the p-layer and attached to the implanted N+ source region at the side. In one embodiment, the JFET further comprises a gate layer, and wherein the gate layer is a dielectric gate structure that enables a fully enhanced channel. In another embodiment, the gate layer is a p-type GaN gate structure that enables a partially enhanced channel.

Claim (Index 1):
An apparatus comprising:\n a drain metal deposited over a N substrate backside; a n-type drift layer epitaxially grown over the N substrate; a p-layer with trench deposited over the n-type drift layer; a lateral channel layer deposited over the p-layer; an implanted N+ source region on side walls of the lateral channel layer; and a source metal attached to the top of the p-layer and attached to the implanted N+ source region at the side.
