Abstract
An improvement is achieved in the performance of a semiconductor device. A semiconductor device includes a pixel including a first active region where a photodiode and a transfer transistor are formed and a second active region for supplying a grounding potential. Over a p-type semiconductor region in the second active region, a plug for supplying the grounding potential is disposed. In an n-type semiconductor region for a drain region of the transfer transistor formed in the first active region, a gettering element is introduced. However, in the p-type semiconductor region in the second active region, the gettering element is not introduced.
