  • Patent number: 8486811
    Abstract: A process for manufacturing a semiconductor device, in which a current flows in a deflected part that includes a semiconductor, includes forming a straight beam having a doubly-clamped beam structure that includes the semiconductor by forming a void under the beam, filling the void with a liquid, and contacting a center of the beam with a bottom of the void by drying the liquid to form the deflected part.
    Type: Grant
    Filed: June 10, 2011
    Date of Patent: July 16, 2013
    Assignee: NEC Corporation

  • Publication number: 20110193145
    Abstract: It is possible to achieve the above interface structure stabilization by forming a structure in which a fraction of Ni atoms are substituted with Pt atoms only in the first interface layer, thereby lowering the interface energy while suppressing the variation of the characteristics of NiSi and NiSi/Si interface to the minimum extent. Therefore, it is possible to contribute to the improvement of the yield ratio of elements or the improvement of reliability through the stabilization of the crystal phase of NiSi. The NiSi is formed, for example, on the surface layer of a source drain in a transistor.

  • Patent number: 6933569
    Abstract: A semiconductor device includes a semiconductor layer formed on an insulator, a gate insulating film formed on the semiconductor layer, a gate electrode formed on the gate insulating film and extending in a first direction, source/drain regions formed in the semiconductor layer on both sides of the gate electrode, a body contact region in the semiconductor layer, a partial isolating region in which a field insulating film thicker than the gate insulating film intervenes between the semiconductor layer and an extending portion of the gate electrode, and a full isolating region in which the semiconductor layer on the insulator is removed. The full isolating region is formed to be in contact with at least a part of a side parallel to the first direction of the source/drain regions.

  • Patent number: 6605397
    Abstract: Pattern data are divided into light beam exposure pattern data and electron beam exposure pattern data free of any overlap margin. Overlap margins are given without size-reduction to the electron beam exposure pattern in order to avoid any disappearance of any parts of the fine pattern.
