Patent ID: 7652314

Claim:
A CMOS image sensor, comprising: a first photodiode and a second photodiode; a floating diffusion node disposed between the first photodiode and the second photodiode; a gate pattern of a first transfer transistor disposed between the first photodiode and the floating diffusion node; a gate pattern of a second transfer transistor disposed between the second photodiode and the floating diffusion node; a gate pattern of a drive transistor disposed to partially overlap with the floating diffusion node; a contact disposed to contact both the floating diffusion node and the gate pattern of the drive transistor simultaneously through a contact hole which is partially shared by a portion of the floating diffusion node and a portion of the gate pattern of the drive transistor; a reset transistor having a first active region which is physically isolated from the floating diffusion node; and a select transistor formed in a “ ” shape, the select transistor sharing a second active region of the drive transistor in common.
