Abstract:
1. A semiconductor structure comprising: a base substrate having a continuous and entirely planar topmost surface; and a multilayered stack located on said base substrate, said multilayered stack comprising, from bottom to top, a first sacrificial phosphide-containing material layer having a first thickness and comprising phosphorus and at least one element selected from Group III and V of the Periodic Table of Elements, a first semiconductor device layer, a second sacrificial phosphide-containing material layer having a second thickness and comprising phosphorus and at least one element selected from Group III and V of the Periodic Table of Elements, and a second semiconductor device layer, wherein the first thickness is less than the second thickness, and wherein an entirety of said first sacrificial material layer is separated from said second sacrificial material layer by at least said first semiconductor device layer.
