OmniVision Launches New CMOS Image Sensor with New Backside Illumination TechnologyOmniVision Technologies today launched its OmniBSITM architecture, a novel sensor design that adopts a radically different approach to traditional CMOS image sensor technology. Using backside illumination (BSI), OmniBSI enables OmniVision to continue offering improved image quality while extending its pixel roadmap down to 0.9 micron pixels, which is the key to continued miniaturization of digital imaging technology. BSI methodology involves turning the CameraChip™ sensor upside down so that it collects light through what was previously the backside of the sensor. This approach differs from conventional front side illumination (FSI) image sensors which can block or deflect light from reaching the pixel, ultimately reducing the fill factor and causing additional problems, such as cross talk, between pixels.
