A foundry-agnostic post-processing method for a wafer is provided. The wafer includes an active surface, a substrate and an intermediate layer interposed between the active surface and the substrate. The method includes removing the wafer from an output yield of a wafer processing foundry, thinning the substrate to the intermediate layer or within microns of the intermediate layer to expose a new surface and bonding the new surface to an alternate material substrate which provides for enhanced device performance as compared to the substrate.
