Abstract
A complementary metal oxide semiconductor (CMOS) image sensing device includes a semiconductor substrate; a photodiode defined on the substrate; a gate dielectric layer provided over the photodiode and the substrate; a polysilicon interconnect contacting a given area of the photodiode via an opening in the gate dielectric layer; a reset transistor coupled to the photodiode; a source follower transistor coupled to the photodiode; and a select transistor coupled to the source follower transistor. The given area of the photodiode defines a node that is coupled to the reset transistor and source follower transistor.
