Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A multi-pixel detector of an image sensor, the multi-pixel detector comprising:
a first photodiode region disposed within a semiconductor substrate to form a first pixel;
a second photodiode region disposed within the semiconductor substrate to form a second pixel adjacent to the first pixel;
a deep trench isolation structure laterally surrounding, collectively, the first photodiode region and the second photodiode region;
a partial isolation structure extending from the deep trench isolation structure, the partial isolation structure including a lateral portion defined by a length and a width disposed between the first photodiode region and the second photodiode region, wherein the length of the lateral portion of the partial isolation structure disposed between the first photodiode region and the second photodiode region is less than a lateral length of the first photodiode region when viewed from a top-view, wherein the length of the lateral portion of the partial isolation structure extends along a longitudinal direction that is perpendicular to the width of the lateral portion of the partial isolation structure when viewed from the top-view, and wherein the length of the lateral portion is greater than the width.
