Claims20
A pixel of an image sensor, comprising:
- a color filter configured to pass visible wavelengths;
- and
- an infrared cut-off filter disposed on the color filter configured to cut off infrared wavelengths.
A pixel array of an image sensor, comprising:
- a first pixel of a first pixel type comprising a color filter configured to pass visible wavelengths and a first infrared cut-off filter disposed on the color filter configured to cut off infrared wavelengths;
- and
- a second pixel of a second pixel type comprising an infrared filter configured to pass the infrared wavelengths.
A method of manufacturing a pixel array of an image sensor, comprising:
- forming a color filter and an infrared filter on a substrate, wherein the color filter is formed on pixels of a first pixel type and the infrared filter is formed on pixels of a second pixel type, the color filter is configured to pass visible wavelengths, and the infrared filter is configured to pass infrared wavelengths;
- forming an infrared cut-off filter on the color filter and the infrared filter, wherein the infrared cut-off filter is configured to cut off infrared wavelengths;
- and
- etching the infrared cut-off filter formed on the infrared filter.
