    摘要: An output circuit in a charge-coupled device (CCD) image sensor includes a charge-to-voltage conversion region, a gain control transistor connected to the charge-to-voltage conversion region and a reset transistor connected in series with the gain control transistor. One or more additional gain control transistors can be connected between the reset transistor and the gain control transistor. The one or more gain control transistors are used to set a capacitance of the charge-to-voltage conversion region to two or more difference capacitance levels. For each capacitance level, a reset voltage and a signal voltage are measured from the charge-to-voltage conversion region. A signal processing device computes multiple signal values for a single charge packet using the measured reset and signal voltages. The signal processing device selects one of the multiple signal values to be the signal value for the pixel.

    摘要: An interline transfer type image sensing device that can be operated at high speed and with low image smear is described. The device incorporates a refractory metal layer which is used for both a light shield over the vertical charge transfer region and as a wiring layer for low resistance strapping of poly crystalline silicon (polysilicon) gate electrodes for the vertical charge transfer region. Plugs provided by a separate metallization layer connect the refractory light shield to the polysilicon gate electrode. These plugs allow high temperature processing after refractory light shield patterning for improved sensor performance without degradation of the polysilicon gate electrode or the refractory lightshield layer.
