Abstract
An Ill-nitride semiconductor based heterojunction power device is disclosed and includes a first and second heterojunction transistors formed on a substrate. The first and second heterojunction transistors include first and second Ill-nitride semiconductor regions formed over the substrate. The first Ill-nitride semiconductor region includes a first heterojunction, a first terminal connected to the first Ill-nitride semiconductor region, a second terminal laterally spaced from the first terminal and connected to the first Ill-nitride semiconductor region, and a first gate region over the first Ill-nitride semiconductor region between the first and second terminals. The second Ill-nitride semiconductor region includes a second heterojunction, a third terminal connected to the second Ill-nitride semiconductor region, a fourth terminal laterally spaced from the third terminal and connected to the second Ill-nitride semiconductor region, first highly doped semiconductor regions of a first conductivity type formed over the second Ill-nitride semiconductor region.
