Sony Develops Back-illuminated CMOS Image Sensor, Realizing High Picture Quality, Nearly Twofold Sensitivity and Low Noise

Tokyo, June 11, 2008 - (JCN Newswire) - Sony Corporation today announced the development of a back-illuminated CMOS image sensor (pixel size: 1.75 micrometer square pixels, five effective mega pixels, 60 frames/s) with significantly enhanced imaging characteristics, including nearly twofold sensitivity[1] and low noise. This improved performance has been achieved by illuminating the backside of the silicon substrate, in contrast to conventional CMOS image sensors based on front-illumination technology.
