Claim:
1. A semiconductor structure, comprising: a first set of one or more fins formed in a first region on an insulated substrate; and a second set of one or more fins formed in a second region on the insulated substrate; wherein the insulated substrate comprises: wherein the first set of one or more fins in the first region comprises a first material layer deposited on the insulator layer; wherein the second set of one or more fins in the second region comprises a second material layer deposited on the insulator layer; wherein the insulator layer is a buried oxide deposited on the silicon substrate in the first and second regions; wherein the first material layer is a group material; wherein the second material layer is a group IV material layer deposited on the buried oxide in the first and second regions; and wherein a bottom surface of the insulator layer in the first region is below a top surface of the silicon substrate in the second region.
