  • Publication number: 20070246750
    Abstract: A partially-depleted silicon-on-insulator (SOI) field-effect transistor (FET) with a reduced off-current is described, as well as methods for manufacturing. This may be accomplished by providing an SOI FET having a lower body potential than in previous SOI FETs. To lower the body potential, carrier traps may be formed mainly in the neutral source and drain regions of the SOI FET by extra over-etching of the gate spacers and the underlying silicon layer.

  • Patent number: 6933590
    Abstract: A convex polycrystalline silicon film is formed on a handle wafer. A semiconductor layer is formed on the polycrystalline silicon film. The semiconductor is thinner on its areas in which the convex polycrystalline silicon film is formed and is thicker on its areas in which the convex polycrystalline silicon film is not formed. An opening is formed in each of those areas of an insulating film which are located under respective thick-film semiconductor areas of the semiconductor layer. The polycrystalline silicon film is formed in the openings to connect electrically the thick-film semiconductor areas and the handle wafer together.
