摘要：
A CMOS imager having an epitaxial layer formed below pixel sensor cells is disclosed. An epitaxial layer is formed between a semiconductor substrate and a photosensitive region to improve the cross-talk between pixel cells. The thickness of the epitaxial layer is optimized so that the collection of signal carriers by the photosensitive region is maximized.
