Abstract:
In one embodiment, a semiconductor structure is provided which includes a base substrate, and a multilayered stack located on the base substrate. The multilayered stack includes, from bottom to top, a first sacrificial material layer having a first thickness, a first semiconductor device layer, a second sacrificial material layer having a second thickness, and a second semiconductor device layer, wherein the first thickness is less than the second thickness.
