Image sensing device

Abstract

An image sensing device includes a substrate including a first surface and a second surface opposite to the first surface; a first well region including impurities of a first conductivity type and disposed in the substrate to be in contact with the second surface; a second well region including impurities of a second conductivity type opposite to the first conductivity type and disposed in the substrate to be in contact with the first well region; a first interconnect electrically connected to the first well region through a first contact plug; a second interconnect electrically connected to the second well region through a second contact plug; and a field-dispersion electrode connected to a third interconnect through a third contact plug and disposed to cover an edge region of the second well region between the first contact plug and the second contact plug.
