Patent ID: 11955497
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 6:
7. An image sensor, comprising:
a pixel isolation structure disposed in a semiconductor substrate to define a first pixel region used to sense a first light, a second pixel region used to sense a second light and a third pixel region used to sense a third light;
a first separation structure disposed in the first pixel region;
a second separation structure disposed in the second pixel region; and
a third separation structure disposed in the third pixel region;
wherein a wavelength of the second light is longer than a wavelength of the first light and is shorter than a wavelength of the third light,
wherein a shape of the second separation structure is different from a shape of the first separation structure and a shape of the third separation structure,
wherein at least one of the separation structures is spaced apart from the pixel isolation structure, and
wherein the pixel isolation structure comprises first protruding portions, which protrude toward a center of the third pixel region and face each other in a first direction, which is perpendicular to a second direction.
