Abstract:
A semiconductor device containing an enhancement mode GaN FET on a III-N layer stack includes a low-doped GaN layer, a barrier layer including aluminum over the low-doped GaN layer, a stressor layer including indium over the barrier layer, and a cap layer including aluminum over the stressor layer. A gate recess extends through the cap layer and the stressor layer, but not through the barrier layer. The semiconductor device is formed by forming the barrier layer with a high temperature MOCVD process, forming the stressor layer with a low temperature MOCVD process and forming the cap layer with a low temperature MOCVD process. The gate recess is formed by a two-step etch process including a first etch step to remove the cap layer, and a second etch step to remove the stressor layer.

Claim (Index 11):
The method of  claim 10 , wherein forming the gate of the enhancement mode GaN FET comprises:\n forming a layer of gate material over the gate dielectric layer in the gate recess and in the area for the gate of the depletion mode GaN FET; and forming the gate of the enhancement mode GaN FET concurrently with the gate of the depletion mode GaN FET from the layer of gate material.
