Abstract:
1. A unit cell of a high power transistor comprising: a transistor having a source region, a drain region and a gate contact, the gate contact being between the source region and the drain region; and first and second ohmic contacts on the source and drain regions, respectively, that respectively define a source contact and a drain contact, the source contact and the drain contact having respective first and second widths, wherein the first width and the second width are different and wherein the source contact and the source region are split into first and second portions such that a portion of a surface of a first epitaxial layer is not disposed beneath the source contact or the source region or the drain contact and the drain region are split into first and second portions such that a portion of the surface of the first epitaxial layer is not disposed beneath the drain contact or the drain region.
