Original Abstract Submitted
An image sensor includes pixels, each including two photodiodes arranged side-by-side in a first direction, a deep trench isolation structure, a floating diffusion region, and transfer gates. The deep trench isolation structure includes an inner structure that extends in a second direction perpendicular to the first direction and that separates the two PDs of pixel from each other in the first direction, and an outer structure that extends in the first and second directions and that separates the pixels from each other in the first and second directions. The floating diffusion region is arranged between a center portion of the outer structure extending in the first direction and an edge of the inner structure. The transfer gates are disposed adjacent to the floating diffusion region such that one or more transfer gates are disposed on each photodiode. For each pixel, the two photodiodes share the floating diffusion region.
