    摘要: A germanium-containing layer is deposited on a single crystalline bulk silicon substrate in an ambient including a level of oxygen partial pressure sufficient to incorporate 1%-50% of oxygen in atomic concentration. The thickness of the germanium-containing layer is preferably limited to maintain some degree of epitaxial alignment with the underlying silicon substrate. Optionally, a graded germanium-containing layer can be grown on, or replace, the germanium-containing layer. An at least partially crystalline silicon layer is subsequently deposited on the germanium-containing layer. A handle substrate is bonded to the at least partially crystalline silicon layer. The assembly of the bulk silicon substrate, the germanium-containing layer, the at least partially crystalline silicon layer, and the handle substrate is cleaved within the germanium-containing layer to provide a composite substrate including the handle substrate and the at least partially crystalline silicon layer. Any remaining germanium-containing layer on the composite substrate is removed.

    摘要: Semiconductor variable capacitor (varactor) devices are provided, which are formed with an array of radial p-n junction structures to provide improved dynamic range and sensitivity. For example, a semiconductor varactor device includes a doped semiconductor substrate having first and second opposing surfaces and an array of pillar structures formed on the first surface of the doped semiconductor substrate. Each pillar structure includes a radial p-n junction structure. A first metallic contact layer is conformally formed over the array of pillar structures on the first surface of the doped semiconductor substrate. A second metallic contact layer formed on the second surface of the doped semiconductor substrate. An insulating layer is formed on the doped semiconductor substrate surrounding the array of pillar structures.

    摘要: This invention provides structures and a fabrication process for incorporating thin film transistors in back end of the line (BEOL) interconnect structures. The structures and fabrication processes described are compatible with processing requirements for the BEOL interconnect structures. The structures and fabrication processes utilize existing processing steps and materials already incorporated in interconnect wiring levels in order to reduce added cost associated with incorporating thin film transistors in the these levels. The structures enable vertical (3D) integration of multiple levels with improved manufacturability and reliability as compared to prior art methods of 3D integration.
