摘要:
A substrate includes a first region and a second region. The first region comprises a III-nitride layer, and the second region comprises a first semiconductor layer. A first transistor (such as an n-type transistor) is formed in and on the III-nitride layer, and a second transistor (such as a p-type transistor) is formed in and on the first semiconductor layer. The III-nitride layer may be indium nitride. In the first region, the substrate may include a second semiconductor layer, a graded transition layer over the second semiconductor layer, and a buffer layer over the transition layer, where the III-nitride layer is over the buffer layer. In the second region, the substrate may include the second semiconductor layer and an insulating layer over the second semiconductor layer, where the first semiconductor layer is over the insulating layer.
