Abstract
A circuit layout for a photosensitive chip includes a semiconductor substrate, a plurality of first circuit lines and a plurality of second circuit lines. The semiconductor substrate has a matrix of photosensitive units. Each photosensitive unit has a first blocking region, a second blocking region and a photosensitive region formed on the semiconductor substrate. The first blocking region is formed between neighboring photosensitive regions aligned in a vertical direction. The second blocking region is formed between neighboring photosensitive regions aligned in a horizontal direction. Free electrons produced by illuminating the photosensitive units are blocked by the first and the second blocking regions.
