Publication number: 20070155039Abstract: A method for manufacturing a CIS reduces or prevents dark current in a photodiode region. In the method, a plurality of gates are formed on a semiconductor substrate, and impurities are implanted in side portions of a predetermined gate to form a photodiode region. Subsequently, a spacer nitride layer is formed and then etched to form a first spacer pattern covering the photodiode region and a second spacer pattern on sidewalls of the rest of the gates. After that, impurities are implanted using the first and second spacer patterns as a mask to form source/drain regions in portions of the semiconductor substrate that are exposed at the side portions of the gate(s). Subsequently, a salicide is formed on the gate and in the exposed portion of the semiconductor substrate.Type: ApplicationFiled: December 27, 2006Publication date: July 5, 2007Inventor: An Do Ki
