Abstract:
A stripe photodiode element, for an image sensor cell, on a semiconductor substrate, comprising:a P type semiconductor substrate, with a first P type dopant concentration, a P well region in a top portion of said P type semiconductor substrate, incorporating a second P type dopant concentration, with the P type dopant concentration of said P well region, greater than the P type dopant concentration of said P type semiconductor substrate; an N type area, located in a first region of said P well region, with said N type area comprised of an N type rectangular shape, and comprised with narrow width N type stripes that extend out from said N type rectangular shape; a heavily doped, P type contact region, in a second region of said P well region, not occupied by said N type area; and a heavily doped, N type contact region, located in said N type rectangular shape.
