An image sensor includes first through fourth pixels. The first pixel includes a first color filter, a first photoelectric conversion device (PD), and a first microlens. The second pixel includes a second PD and a first filling portion. The third pixel includes a third PD and a second filling portion. The fourth pixel includes a fourth PD, a second microlens, and a second color filter different from the first color filter. The second pixel is adjacent to the first pixel. The third pixel is adjacent to the second pixel. The second and third pixels do not comprise any one of a red, blue, and green color filter. Each of the first and second filling portions is configured to transmit light of wavelengths corresponding to blue, red, and green to the second and third PDs, respectively. The first color filter is configured to transmit light of the wavelength corresponding to blue.

Image sensor and manufacturing process thereof

An image sensor includes: a substrate including a plurality of first and second pixels; a light blocking pattern providing a plurality of first spaces respectively disposed on the first pixels and at least one second space disposed on the plurality of second pixels; a plurality of color filters respectively disposed in the plurality of first spaces; and a microlens layer including a plurality of first microlenses respectively disposed on the plurality of color filters, at least one filling portion disposed in the at least one second space, and at least one second microlens disposed on the at least one filling portion, wherein the microlenses are disposed at the same height as each other, and wherein the at least one filling portion and the at least one second microlens comprise an integrated structure without an interface between the at least one filling portion and the at least one second microlens.

An image sensor includes: a substrate having a first surface and a second surface that are opposite to each other; a plurality of color filters on the substrate; a fence pattern between adjacent color filters of the plurality of color filters; and a protective layer between the substrate and the plurality of color filters, wherein the protective layer covers the fence pattern. The fence pattern includes: a first fence pattern having a first bottom surface and a first top surface that are opposite to each other; and a second fence pattern on the first top surface of the first fence pattern. A width at the first bottom surface of the first fence pattern is less than a width of the second fence pattern, and the protective layer covers a sidewall of the first fence pattern.
