摘要： A solid-state image sensor is provided. The solid-state image sensor includes photoelectric conversion elements and a color filter layer disposed above the photoelectric conversion elements. The color filter layer has a first color filter segment and a second color filter segment adjacent to the first color filter segment. The first color filter segment and the second color filter segment correspond to different colors. The solid-state image sensor further includes a light-splitting structure disposed in the first color filter segment or the second color filter segment and a grid structure disposed between the first color filter segment and the second color filter segment. The light-splitting structure is separated from the grid structure.

摘要： An image sensor includes a group of sensor units and a color filter layer disposed within the group of sensor units. The image sensor further includes a dielectric structure and a plurality of polarization splitters disposed corresponding to the color filter layer. Each of the plurality of polarization splitters has a first meta element extending in a first direction from top view and a second meta element extending in a second direction from top view. The second direction is perpendicular to the first direction.

摘要： An image sensor includes a sensor unit, a sensing portion disposed within the sensor unit, and an isolation structure corresponding to the sensing portion. The isolation structure includes a first deep trench isolation (DTI) structure surrounding the sensor unit from top view, and a second deep trench isolation structure laterally enclosed by the first deep trench isolation structure. The second deep trench isolation structure is located close to a corner of the sensor unit defined by the first deep trench isolation structure. The second deep trench isolation structure is asymmetrical with respect to a horizontal middle line or a vertical middle line within the sensor unit.
