    Abstract: To provide a photoelectric conversion device with improved photoelectric conversion characteristics and cost competitiveness. A photoelectric conversion device including a semiconductor junction has a semiconductor layer in which a needle-like crystal is made to grow over an impurity semiconductor layer. The impurity semiconductor layer is formed of a microcrystalline semiconductor and includes an impurity imparting one conductivity type. An amorphous semiconductor layer is deposited on a microcrystalline semiconductor layer by setting the flow rate of a dilution gas (typically silane) to 1 time to 6 times the flow rate of a semiconductor source gas (typically hydrogen) at the time of deposition. Thus, a crystal with a three-dimensional shape tapered in a direction of the deposition of a film, i.e., in a direction from the microcrystalline semiconductor layer to the amorphous semiconductor layer is made to grow.

    Abstract: A microelectromechanical system switch may include a relatively stiff cantilevered beam coupled, on its free end, to a more compliant or flexible extension. A contact may be positioned at the free end of the cantilevered beam. The extension reduces the actuation voltage that is needed and compensates for the relative stiffness of the cantilevered beam in closing the switch. In opening the switch, the stiffness of the cantilevered beam may advantageously enable quicker operation which may be desirable in higher frequency situations.

  • Patent number: 7323750
    Abstract: A bipolar transistor is provided, which is low in collector-to-emitter saturation voltage, small in size and to be manufactured by a reduced number of processes, and a semiconductor device formed with such a bipolar transistor and a MOS transistor on a same substrate. A high concentration region for reducing the collector-to-emitter saturation voltage VCE(sat) is formed in a manner surrounding a base region of an NPN transistor. This high concentration region is not necessarily formed in such a depth as reaching a buried layer, and can be reduced in the spread in a lateral direction. Because a high concentration region can be formed in a same process as upon forming source and drain regions for an NMOS transistor to be formed together with an NPN transistor on a same silicon substrate, it is possible to omit a diffusion process exclusive for forming a high concentration region and hence to manufacture a semiconductor device through a reduced number of processes.

The gate dielectric layer of the TFT includes a silicon nitride layer, a dielectric layer and a silicon nitride layer, and the etching selectivity of the amorphous silicon layer over the dielectric layer is not less than about 5.0.
