摘要:
In one embodiment, a method of forming a semiconductor device includes forming a first porous semiconductor layer over a top surface of a substrate. A first epitaxial layer is formed over the first porous semiconductor layer. A circuitry is formed within and over the first epitaxial layer. The circuitry is formed without completely oxidizing the first epitaxial layer.
