A CMOS image sensor and a method of fabricating the same are provided. The image sensor includes a blocking layer protecting a photodiode at a diode region. The blocking layer is formed to cover a top of the diode region and extended to an active region so as to cover a transfer gate and a floating diffusion layer. Therefore, the floating diffusion layer may not be attacked by an etching during a formation of sidewall spacers of various gates or by ion implantation during a formation of a junction region of a DDD or LDD structure, thus reducing a leakage current and a dark current at the floating diffusion layer.
