    摘要: A semiconductor device having an SOI FET comprising a silicon body on an insulating layer on a conductive substrate. A gate dielectric and a gate are provided on a surface of the silicon body, and a source and a drain are provided on two sides of the gate. A buried body contact to the substrate conductor is provided below a third side of the gate. The buried body contact does not extend to the top surface of the silicon body. The body contact is separated from the gate by a second dielectric having a thickness typically greater than that of the gate dielectric. The body contact is a plug of conductive material, and the second dielectric coats the body contact under the gate. The FET can be used in an SRAM circuit or other type of circuit having a silicon-on-insulator (SOI) construction.

    摘要: A method and apparatus are provided for forming a silicide on a semiconductor substrate by integrating under a constant vacuum the processes of removing an oxide from a surface of a semiconductor substrate and depositing a metal on the cleaned surface without exposing the cleaned surface to air. The method and apparatus of the present invention eliminates the exposure of the cleaned substrate to air between the oxide removal and metal deposition steps. This in-situ cleaning of the silicon substrate prior to cobalt deposition provides a cleaner silicon substrate surface, resulting in enhanced formation of cobalt silicide when the cobalt layer is annealed.
