SHARED-PIXEL-TYPE IMAGE SENSOR AND METHOD OF FABRICATING THE SAME |
摘要 |
A shared-pixel-type image sensor including a shared floating diffusion region formed in a semiconductor substrate; first and second adjacent photoelectric conversion regions sharing the floating diffusion region; two transmission elements that alternately transfer electric charges accumulated in the first and second photoelectric conversion regions to the shared floating diffusion region, respectively; a drive element for outputting the electric charges of the shared floating diffusion region; a first contact formed on the floating diffusion region; a second contact formed on the drive element; and a local wire that connects the first and second contacts to electrically connect the floating diffusion region and the drive element, wherein the local wire is formed at a level lower than respective top surfaces of the first and second contacts.
