Abstract
A complementary metal oxide semiconductor (CMOS) image sensor is provided that includes a substrate including a first surface, a second surface facing the first surface, and a first recess region that is recessed from the first surface toward the second surface. The CMOS image sensor further includes a transfer gate on the substrate, and a source follower gate on the first recess region. The source follower gate is within the first recess region and partially covers a portion of the first surface of the substrate.
