Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 17:
18. An image sensor, comprising:
a first sensor including first, second, and third photodiodes; and
a second sensor, the second sensor including
a first wavelength separation filter overlapping the first photodiode in a vertical direction extending perpendicular to an upper surface of a substrate of the image sensor,
a second wavelength separation filter overlapping the second photodiode in the vertical direction, and
a third wavelength separation filter overlapping the third photodiode in the vertical direction,

wherein the first wavelength separation filter includes at least one first colorant configured to selectively transmit incident light in a first wavelength spectrum and at least one first photoelectric conversion material configured to absorb the incident light in at least one of a second wavelength spectrum or a third wavelength spectrum,
wherein the second wavelength separation filter includes at least one second colorant configured to selectively transmit the incident light in the second wavelength spectrum and at least one second photoelectric conversion material configured to absorb the incident light in at least one of the first wavelength spectrum or the third wavelength spectrum,
wherein the third wavelength separation filter includes at least one third colorant configured to selectively transmit the incident light in the third wavelength spectrum and at least one third photoelectric conversion material configured to absorb the incident light in at least one of the first wavelength spectrum or the second wavelength spectrum, and
the first wavelength spectrum, the second wavelength spectrum, and the third wavelength spectrum are different wavelength spectra of a visible wavelength spectrum.
