Abstract:
Implementations of an ohmic contact for a gallium nitride (GaN) device may include: a first layer including aluminum coupled directly with the GaN device; the GaN having a heterostructure with an undoped GaN channel and a semi-insulating aluminum gallium nitride (AlGaN) barrier, all the foregoing operatively coupled with a substrate; a second layer including titanium coupled over the first layer; and a third layer including an anti-diffusion material coupled with the second layer. A passivation layer may be coupled between the AlGaN barrier and the first layer of the ohmic contact. The passivation layer may surround the ohmic contact.

Claim (Index 5):
The ohmic contact of  claim 1 , wherein the first layer comprises one of the group of elemental Al, aluminum copper (AlCu), aluminum silicon copper (AlSiCu), aluminum silicon (AlSi), aluminum copper tungsten (AlCuW), and any combination thereof.
