  • Patent number: 6013930
    Abstract: A bottom-gate-type semiconductor device comprising crystalline semiconductor layers, in which the source/drain regions each have a laminate structure comprising a first conductive layer (n.sup.+ layer), a second conductive layer (n.sup.- layer) of which the resistance is higher than that of the first conductive layer, and an intrinsic or substantially intrinsic semiconductor layer (i-layer). In this, the n.sup.- layer functions as an LDD region, and the i-layer functions as an in-plane offset region. The semiconductor device has high reliability and high reproducibility, and is produced in a simple process favorable to mass-production.

  • Patent number: 6011277
    Abstract: A thin film field effect transistors and manufacturing method for the same are described. The channel region of the transistor is spoiled by an impurity such as oxygen, carbon, nitrogen. The photosensitivity of the channel region is reduced by the spoiling impurity and therefore the transistor is endowed with immunity to illumination incident thereupon which would otherwise impair the normal operation of the transistor. The spoiling impurity is not introduced into transistors which are located in order not to receive light rays.

  • Patent number: 6010129
    Abstract: A sheet sorter includes a plurality of bins arranged in a vertical direction each of which receives a plurality of sheets discharged from an image recording apparatus and forms thereon a stack of sheets. A sheet transfer mechanism transfers the sheets discharged from the image recording apparatus, and an indexer receives the sheets from the sheet transfer mechanism and distributes the sheets to the respective bins through the sheet inlet ends. A sheet stack ejector mechanism ejects the stack of sheets on each of the bins beyond the sheet inlet end of the bin by a predetermined length, thereby giving a stapler access to the stack of sheets. The ejector mechanism includes a guide rail which extends in a vertical direction through the bins, and a sheet stack ejector member which is mounted on the guide rail to be movable up and down along the guide rail and is adapted to eject the stacks of sheets on the respective bins one by one toward the stapler.

  • Patent number: 6008101
    Abstract: It is intended to provide a technique of separately forming thin-film transistors disposed in a peripheral circuit area and those disposed in a pixel area in accordance with characteristics required therefor in a manufacturing process of semiconductor devices to constitute a liquid crystal display device. In an annealing step by laser light illumination, laser light is selectively applied to a semiconductor thin-film by partially masking it. For example, to illuminate the peripheral circuit area and the pixel area with laser light under different conditions in manufacture of an active matrix liquid crystal display device, laser light is applied at necessary illumination energy densities by using a mask. In this manner, a crystalline silicon film having a necessary degree of crystallinity in a selective manner can be obtained.

    Abstract: A plurality of air conditioning system control units are connected to each other through a communication line (20). Discharge resistors (R1, R2) are provided for discharging residual charges of the communication line (20). The control unit has a power superposition circuit (50) for applying a direct-current voltage and outputs an identification number signal from the power superposition circuit (50) to the communication line (20). The control unit further has a polarity select circuit (60) having a negative-polarity resistance characteristic that current increasingly flows as an applied voltage is lowered, and a voltage discriminating circuit (70) for detecting the terminal voltage of the polarity select circuit (60). When detecting the voltage of the communication line (20), the control unit determines whether its own control unit is a master unit or a slave unit according to output signals from the voltage discriminating circuit (70) and a polarity discriminating circuit (3C).

  • Patent number: 6001712
    Abstract: In an insulated gate field effect semiconductor device, the gate electrode formed on the gate insulating film includes the first and second semiconductor layers as a double layer. An impurity for providing one conductivity type is not contained in first semiconductor layer which is in contact with a gate insulating film and is contained at a high concentration in the second semiconductor layer which is not in contact with the gate insulating film. Accordingly, By existence of the first semiconductor layer is which the impurity is not doped, the impurity is prevented from penetrating through the gate insulating film from the gate electrode and diffusing into the channel forming region. Also, by existence of the second semiconductor layer in which high concentration impurity is doped, the gate electrode has low resistance.
