ABSTRACT:
A microelectronic structure includes a substrate, a semiconductor island on the substrate, and a filler material on the substrate and surrounding the semiconductor island. The semiconductor island includes a first semiconductor material and has a planar island surface opposite the substrate. The filler material includes a layer of a second semiconductor material having a planar single crystal surface adjacent the planar island surface opposite the substrate so that the planar island surface and the planar single crystal surface together define a smooth planar surface. The first semiconductor material can be diamond, and the second semiconductor material can be silicon. In addition, a microelectronic circuit can be provided on the filler material.
