Abstract
An example CMOS image sensor has pixel units and protection regions. The pixel unit has a light sensing region for converting an incident light into an electrical signal and an active region for controlling the transfer of the electrical signal. Each pixel unit is isolated by an element isolation layer. The protection region, which is located between each element isolation layer, prevents crosstalk generated between each pixel unit while the incident light is converted to the electrical signal. The protection region may include a well and a junction.
