Claim:
1. An imaging device, comprising: a first area including a first set of photodiodes that share a first floating diffusion region and a second set of photodiodes that share a second floating diffusion region, wherein the first set of photodiodes and the second set of photodiodes are arranged along a first direction; a second area including a first amplification transistor coupled to the first floating diffusion region, a second amplification transistor coupled to the second floating diffusion region, an element isolation region, and a well contact region, wherein the first area and the second area are arranged along a second direction perpendicular to the first direction; wherein the element isolation region is arranged between the first amplification transistor and the second amplification transistor and comprises an insulating material; a first reset transistor coupled to the first floating diffusion region; a second reset transistor coupled to the second floating diffusion region; at least one first transfer transistor coupled to the first floating diffusion region; and at least one second transfer transistor coupled to the second floating diffusion region, wherein the well contact region is arranged between the first amplification transistor and the second amplification transistor along the first direction in the second area, wherein the imaging device further comprises a third set of photodiodes that share a third floating diffusion region, and wherein the third set of photodiodes is adjacent to the first set of photodiodes across the second area along the second direction.
