Abstract
A circuit structure includes a substrate and a patterned dielectric layer over the substrate. The patterned dielectric layer includes a plurality of vias; and a number of group-III group-V (III-V) compound semiconductor layer. The III-V compound semiconductor layers include a first layer in the vias, a second layer over the first layer and the dielectric layer, and a bulk layer over the second layer.
