A semiconductor structure including a first substrate, and an epitaxial layer bonded to the substrate. The epitaxial layer has a threading dislocation density of less than 10<7 >cm<-2 >and an in-plane lattice constant that is different from that of the first substrate and a second substrate on which the epitaxial layer is fabricated. In another embodiment, there is provided a method of processing a semiconductor structure including providing a first substrate; providing a layered structure including a second substrate having an epitaxial layer provided thereon, the epitaxial layer having an in-plane lattice constant that is different from that of the first substrate and a threading dislocation density of less than 10<7 >cm<-2>; bonding the first substrate to the layered structure; and removing the second substrate.
