Abstract:
Some embodiments of the present disclosure relate to a high electron mobility transistor (HEMT) which includes a heterojunction structure arranged over a semiconductor substrate. The heterojunction structure includes a first III/V semiconductor layer, and a second III/V semiconductor layer arranged over the first III/V semiconductor layer. Source and drain regions are arranged over the second III/V semiconductor layer and are spaced apart laterally from one another. A gate structure is arranged over the heterojunction structure and is arranged between the source and drain regions. The gate structure is made of a third III-nitride material. A first passivation layer is disposed about sidewalls of the gate structure and is made of a fourth III-nitride material.

Claim (Index 9):
An enhancement mode high electron mobility transistor (HEMT) formed on a substrate, comprising:\n an AlN buffer layer over the substrate; an AlGaN buffer layer over the AlN buffer layer; a GaN channel layer over the AlGaN buffer layer; an AlGaN barrier layer over the GaN channel layer, wherein source and drain regions are over an upper planar surface of the AlGaN barrier layer; a GaN gate structure in direct contact with the upper planar surface of the AlGaN barrier layer, wherein the GaN gate structure is doped with acceptor or donor impurities and has a gate structure upper surface and gate structure outer sidewalls; and a conformal AlN or BN passivation layer in direct contact with the upper planar surface of the AlGaN barrier layer and extending over the gate structure upper surface and abutting the gate structure outer sidewall.
