Abstract

SNR (Signal-to-Noise Ratio) at low light condition is a key performance of image sensor. To improve SNR performance with high sensitivity and low crosstalk, advanced light-guide and backside illumination (BSI) pixel technologies are developed. Comparing with the conventional frontside illumination (FSI) technology, SNR10 is improved by 16% for light-guide and by 36% for BSI at the 1.4um pixel node.
