  • Patent number: 7973346
    Abstract: Disclosed is a image sensor (e.g., a CMOS image sensor) including pixels each having a transfer transistor and a drive transistor, in which the gate of at least one of the transistors has a boosting gate disposed over it comprised of a conductive film pattern with interposing an insulation film. Thus, a voltage applied to the boosting gate is capacitively coupled to at least one of the transfer gate of the transfer transistor and a drive gate of the drive transistor. The transfer gate is supplied with the sum of the transfer voltage and the boosting gate-coupling voltage as a result and there is no need for providing a high voltage generator for the image sensor. The dynamic range of operation may be enhanced if such a coupling voltage is applied to the drive gate of the drive transistor.

  • Patent number: 7566925
    Abstract: Image sensors and methods of fabricating the same are provided. The image sensor includes a blocking pattern disposed on photodiodes. The blocking pattern is formed of insulation material having a metal diffusion coefficient which is lower than a silicon oxide diffusion coefficient. Therefore, dark defects of the image sensor are reduced. In addition, the image sensor includes a color-ratio control layer. The color ratio control layer controls color ratios between the sensitivities to blue, green and red. As a result, color distinction of the picture that is embodied by the image sensor can be improved.
