Multicolor Imager Having A Stacked Pixel-element Structure, E.g. Npn, Npnpn Or Mqw Elements (epo) Patents (Class 257/E27.135)
  • Patent number: 7407830
    Abstract: A CMOS imaging device including a two pixel detection system for red, green, and blue light. One pixel detects red and blue light and another pixel detects green light. The detection of red and blue is based on wavelength and the device is structured such that in the red/blue pixel, detection of blue light is at a shallow substrate depth, while detection of red is at a deeper substrate depth. The pixel array is structured such that the red/blue pixel is adjacent to the green pixel and alternates between red/blue and green pixels. The invention is also related to methods of forming such an imager array and pixels.

  • Patent number: 7365380
    Abstract: An object of the present invention is to provide a photoelectric conversion device, wherein improvement of charge transfer properties when charge is output from a charge storage region and suppression of dark current generation during charge storage are compatible with each other. This object is achieved by forming a depletion voltage of a charge storage region in the range from zero to one half of a power source voltage (V), forming a gate voltage of a transfer MOS transistor during a charge transfer period in the range from one half of the power source voltage to the power source voltage (V) and forming a gate,voltage of the transfer MOS transistor during a charge storage period in the range from minus one half of the power source voltage to zero (V).
