OmniVision has developed a radically different approach to traditional CMOS image sensor technology. Using backside illumination (BSI), the OmniBSI technology enables OmniVision to continue miniaturization of digital imaging technology. The methodology involves turning the sensor upside down so that it collects light through what was previously the backside of the sensor. Current front side illumination (FSI) sensors can block or deflect light from reaching the pixel, and this novel approach optimizes light absorption...
