Abstract

The present invention relates to a CMOS image sensor including an infrared pixel with enhanced spectral characteristics in which a stepped portion is formed between color filters of RGB pixels and a filter of an infrared pixel, and a manufacturing method thereof. A stepped portion is formed between color filters and an infrared filter according to respective pixels and the thicknesses of the filters are arbitrarily adjusted regardless of the characteristics of material in the formation of the color filters and the infrared filter, so that crosstalk characteristics are improved.
