    摘要: A method of providing a freestanding semiconductor layer on a conventional SOI or bulk-substrate silicon device includes forming an amorphous or polycrystalline mandrel on a monocrystalline base structure. A conformal polycrystalline semiconductor layer is then formed on the mandrel and on the base structure, wherein the polycrystalline layer contacts the base structure. The polycrystalline semiconductor layer is then recrystallized so that it has a crystallinity substantially similar to that of the base structure. Thus, a freestanding semiconductor layer is formed with a high degree of control of the thickness and height thereof and maintaining a uniformity of thickness.

    摘要: Disclosed is a capacitor structure and method for forming the same. This structure has a conductive substrate, conductive fins extending above the substrate, and trenches extending into the substrate. These trenches are positioned between locations where the fins extend above the substrate. The invention includes an insulator in the trenches and covering the fins. This insulator separates the substrate and fins from a conductive top plate that covers the fins and fills the trenches. A bottom plate contact electrically connects the fins and the substrate such that the fins and the substrate comprise a bottom plate of the capacitor structure.
