Patent ID: 11925040
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 18:
19. An image sensor, comprising:
a substrate having first and second opposing surfaces thereon and comprising a semiconductor material of first conductivity type;
a microlens array on the second surface of the substrate;
a first pixel comprising a first color filter on the second surface of the substrate, and a first photoelectric conversion region within a first portion of the substrate, which extends between the first and second opposing surfaces of the substrate and extends between the first color filter and the first surface of the substrate; and
a second pixel having different light receiving characteristics relative to the first pixel, said second pixel comprising:
a pixel electrode on the second surface of the substrate;
a photoelectric conversion layer comprising a perovskite material, on the pixel electrode; and
a transparent electrode on the photoelectric conversion layer;

wherein a color filter is omitted from a light receiving path of the second pixel;
wherein the first photoelectric conversion region comprises a semiconductor material of second conductivity type, which forms a P-N junction photodiode with the substrate; and
wherein the pixel electrode, the photoelectric conversion layer and the transparent electrode of the second pixel extend between a corresponding microlens within the microlens array and the second surface of the substrate.
