Abstract
A semiconductor structure includes a substrate including a p-type region and an n-type region, wherein the n-type region is in the p-type region and a distance between a top surface of the substrate and the n-type region is less than a distance between the top surface of the substrate and the p-type region. A buffer layer is over the n-type region and a first III-V compound layer is over the buffer layer. A second III-V compound layer is over the first III-V compound layer and a metal structure is over the second III-V compound layer. The metal structure may include a coplanar waveguide or a high electron mobility transistor.
