Abstract:
An image sensor including a deep guard ring and a noise blocking area and a method of manufacturing the same. The image sensor includes the deep guard ring and a deep P well surrounding the noise blocking area, thereby preventing crosstalk between adjacent pixels. In addition, an ion implantation layer is divided by the noise blocking area, so that substrate crosstalk is effectively eliminated.
