A system and method for image sensing is disclosed. An embodiment comprises a substrate with a pixel region and a logic region. A first resist protect oxide (RPO) is formed over the pixel region, but not over the logic region. Silicide contacts are formed on the top of active devices formed in the pixel region, but not on the surface of the substrate in the pixel region, and silicide contacts are formed both on the top of active devices and on the surface of the substrate in the logic region.
