Abstract:
An image sensor for reducing crosstalk includes anti-reflection films which are formed between a plurality of metal wire lines of the lowest metal wiring layer and a semiconductor substrate and between one of the metal wiring layers and another metal wiring layer. The image sensor having the anti-reflection films according to the present invention can reduce color crosstalk and noises in comparison with a conventional image sensor by using the anti-reflection films formed above the surroundings of the photodiodes.
