Abstract

See full text

The present disclosure provides CMOS image sensors. A CMOS image sensor includes a substrate having a first region and a second region connecting with the first region at a first end of the first region; a transfer transistor formed on the surface of the substrate in the second region; a floating diffusion (FD) region formed in the surface of the substrate at one side of the transfer transistor in the second region; a third implanting region formed in the surface of the substrate 200 in the first region, being formed from a first implanting region; a second implanting region and an adjacent fifth implanting region formed under the third implanting region; and a fourth implanting region formed under the second implanting region and the fifth implanting region, being electrically connected with the third implanting region by the fifth implanting region.
