Claim 13:
14. The device of claim 13, wherein the top surface of the single upper semiconductor portion further includes:
a third multi-facet surface;
a second flat surface extending from the second multi-facet surface to the third multi-facet surface, the third multi-facet surface being positioned at a higher level above the substrate than the second flat surface and the second flat surface being parallel to the top surface of the substrate; and
a third flat surface extends from the third multi-facet and does not interface with the second flat surface, the third multi-facet surface being positioned at a higher level above the substrate than the third flat surface and the third flat surface being parallel to the top surface of the substrate.
