Patent ID: 7524717

Claim:
A method of fabricating a complementary metal oxide semiconductor (CMOS) image sensor, the method comprising: forming field isolation film patterns defining active regions in a semiconductor substrate; forming a storage diffusion region in one of the active regions; forming a first transfer gate, a second transfer gate, a read gate, and a reset gate on the semiconductor substrate; forming an upper capacitor electrode over the storage diffusion region; forming a photodiode region in an active region of the semiconductor substrate between the first and second transfer gates; forming a read diffusion region, a floating diffusion region, and a reset diffusion region in the semiconductor substrate using a mask covering the photodiode region and the storage diffusion region; and, forming connection lines respectively contacting the first transfer gate, the second transfer gate, the read gate, the reset gate, the read diffusion region, the floating diffusion region, and the reset diffusion region; wherein the connection line contacting the read diffusion region is connected to the connection line contacting the floating diffusion region.
