Abstract

Semiconductor devices and methods of manufacture are provided whereby fences are formed over a substrate and III-V materials are grown over the substrate, wherein the fences block growth of the III-V materials. As such, smaller areas of the III-V materials are grown, thereby preventing stresses that occur with the growth of larger sheets.
