Abstract
An image capturing device is provided. The device includes a substrate comprising a pixel region, a peripheral region and a trench region, in which trenches are formed, between the pixel region and the peripheral region. The plurality of trenches include first trenches arranged to be spaced apart from each other in a first direction along a first side of an outer edge of the pixel region and second trenches arranged to be spaced apart from each other in the first direction. The first and second trenches are arranged to be spaced apart from each other in a second direction crossing the first direction. The first and second trenches are arranged so that, any straight line path which connects, without overlapping any one of the first and second trenches, the first side and the peripheral region, does not exist.
Claims22
An image capturing device comprising:
- a substrate having a first surface and a second surface, and comprising (1) a pixel region including a plurality of pixels each including a photo conversion element arranged between the first surface and the second surface, (2) a peripheral region arranged around the pixel region, and (3) a trench region, arranged between the pixel region and the peripheral region, and including a plurality of trenches extending from the first surface toward the second surface,
- wherein the plurality of trenches include, between a first side of an outer edge of the pixel region and an inner-side edge of the peripheral region, (1) a plurality of first trenches arranged to be spaced apart from each other in a first direction parallel to the first side and (2) a plurality of second trenches arranged to be spaced apart from each other in the first direction,
- wherein the plurality of first trenches and the plurality of second trenches are arranged to be spaced apart from each other in a second direction crossing the first direction, and
- wherein the plurality of first trenches and the plurality of second trenches are arranged so that, in orthographic projection for the first surface of the substrate, any straight line path which connects, without passing through any one of the plurality of first trenches and the plurality of second trenches, the first side and the inner-side edge of the peripheral region, does not exist.
A camera comprising:
- an image capturing device comprising a substrate, the substrate having a first surface and a second surface, and comprising (1) a pixel region including a plurality of pixels each including a photo conversion element arranged between the first surface and the second surface, (2) a peripheral region arranged around the pixel region, and (3) a trench region arranged between the pixel region and the peripheral region, and including a plurality of trenches extending from the first surface toward the second surface, wherein the plurality of trenches include, between a first side of an outer edge of the pixel region and an inner-side edge of the peripheral region, (1) a plurality of first trenches arranged to be spaced apart from each other in a first direction parallel to the first side and (2) a plurality of second trenches arranged to be spaced apart from each other in the first direction, wherein the plurality of first trenches and the plurality of second trenches are arranged to be spaced apart from each other in a second direction crossing the first direction, and wherein the plurality of first trenches and the plurality of second trenches are arranged so that, in the orthographic projection for the first surface of the substrate, any straight line path which connects, without passing through any one of the plurality of first trenches and the plurality of second trenches, the first side and the inner-side edge of the peripheral region, does not exist;
- and
- a signal processor configured to process a signal obtained by the image capturing device.
