Abstract
Design constraints for a self protecting GaN HFET and in general any group III V HFET are described. The design constraints depend on the separation between the gate and the drain and the thickness of the buffer material between the channel layer and the substrate. In one embodiment the buffer region is thinned to provide a preferred breakdown location.
