Abstract
Various embodiments of the present disclosure are directed towards a method for forming a pixel sensor. The method comprises forming a photodetector in a substrate. The substrate is patterned to define an opening above the photodetector. A gate electrode is formed within the opening, where the gate electrode has a top conductive body overlying a bottom conductive body. A first segment of a sidewall of the top conductive body contacts the bottom conductive body. A floating diffusion node is formed in the substrate laterally adjacent to the gate electrode. A second segment of the sidewall of the top conductive body overlies the floating diffusion node.
