Abstract:
A vertical JFET is provided. The JFET is mixed with lateral channel structure and p-GaN gate structure. The JFET has an improved barrier layer for p-GaN block layer and enhanced Ohmic contact with source. In one embodiment, regrowth of lateral channel is provided so that counter doping surface Mg will be buried. In another embodiment, a dielectric layer is provided to protect p-type block layer during the processing, and later make Ohmic source and p-type block layer. Method of a barrier regrown layer for enhanced lateral channel performance is provided where a regrown barrier layer is deposited over the drift layer. The barrier regrown layer is an anti-p-doping layer. Method of a patterned regrowth for enhanced Ohmic contact is provided where a patterned masked is used for the regrowth.

Claim (Index 13):
The method of  claim 12 , wherein the contact gap is formed by removing a dielectric regrowth mask deposited over the P-type block layer before the regrown of the first regrown N-type layer.
