  • Patent number: 8912583
    Abstract: The present invention provides a thin-film transistor manufactured on a transparent substrate having a structure of a top gate type crystalline silicon thin-film transistor in which a light blocking film, a base layer, a crystalline silicon film, a gate insulating film, and a gate electrode film arranged not to overlap at least a channel region are sequentially formed on the transparent substrate; wherein the channel region having channel length L, LDD regions having LDD length d on both sides of the channel region, a source region, and a drain region are formed in the crystalline silicon film; the light blocking film is divided across the channel region; and interval x between the divided light blocking films is equal to or larger than channel length L and equal to or smaller than a sum of channel length L and a double of LDD length d (L+2d).

  • Patent number: 8901638
    Abstract: A trench-gate semiconductor device is disclosed, in which the player (10,6) which forms the body region (in a n-channel device) extends adjacent the trench (4) deeper into the device, to lie adjacent a lower trench electrode (3b, 3c). Since the p-layer extension (6) forms part of the channel, it must be very low doped, in order not to increase unduly the channel resistance in the on-state. The replacement of some of the out-diffusion resistance in the drift region by the (smaller) channel resistance results in a lower over-all Rdson. In the off-state, the p-layer forms, together with the underlying n-drift layer, a non-abrupt function, so that the depletion region in the off-state extends closer to the top surface (2) than for a conventional RSO trench-MOS, being split between the p- and n-layers, rather than all being in the n-drift region.

  • Patent number: 8865514
    Abstract: The concentration of a constituent within a chalcogenide film used to form a chalcogenide containing semiconductor may be adjusted post deposition by reacting the chalcogenide film with a material in contact with the chalcogenide film. For example, a chalcogenide film containing tellurium may be coated with a titanium layer. Upon the application of heat, the titanium may react with the tellurium to a controlled extent to reduce the concentration of tellurium in the chalcogenide film.

  • Patent number: 8810005
    Abstract: A bipolar device with an entirely monocrystalline intrinsic base to extrinsic base link-up region. To form the device, a first extrinsic base layer, which is amorphous or polycrystalline, is deposited such that it contacts an edge portion of a monocrystalline section of an intrinsic base layer through an opening in a dielectric layer. A second extrinsic base layer is deposited on the first. An anneal is performed, either before or after deposition of the second extrinsic base layer, so that the extrinsic base layers are monocrystalline. An opening is formed through the extrinsic base layers to a dielectric landing pad aligned above a center portion of the monocrystalline section of the intrinsic base layer. The dielectric landing pad is removed and a semiconductor layer is grown epitaxially on exposed monocrystalline surfaces of the extrinsic and intrinsic base layers, thereby forming the entirely monocrystalline intrinsic base to extrinsic base link-up region.
