Claim Text:
1. A semiconductor structure comprising: a semiconductor substrate comprising a first semiconductor surface and a second semiconductor surface, wherein said first semiconductor surface is vertically offset and located above said second semiconductor surface; an oxide region located directly on at least one of the first semiconductor surface and the second semiconductor surface; a first set of first semiconductor fins having a first height and located above said first semiconductor surface of the semiconductor substrate; and a second set of second semiconductor fins having a second height and located above the second semiconductor surface, wherein the second height is different than the first height and each first semiconductor fin and each second semiconductor fin has a topmost surface, and the topmost surfaces of the first and second semiconductor fins are coplanar with each other, and further wherein one vertical sidewall surface of each first semiconductor fin and each second semiconductor fin that is present on said oxide region is vertically aligned to an outermost vertical edge of said oxide region.
