Abstract
An image sensor includes a sensor layer and at least one metal layer. The sensor layer includes a plurality of sensing elements arranged as a 2-dimensional array along a first direction and a second direction. Each of the at least one metal layer includes a plurality of metal wires configured to form a plurality of apertures for passing lights to the plurality of sensing elements. At least one of the plurality of metal wires forming the plurality of apertures is disposed along a third direction different from the first direction and the second direction.
Claims9
An image sensor, comprising:
- a sensor layer, comprising a plurality of sensing elements arranged as a 2-dimensional array along a first direction and a second direction;
- and
- at least one metal layer, each comprising a plurality of metal wires configured to form a plurality of apertures for passing lights to the plurality of sensing elements;
- wherein at least one of the plurality of metal wires forming the plurality of apertures is entirely disposed along a third direction different from the first direction and the second direction.
An image sensor, comprising:
- a sensor layer, comprising a plurality of sensing elements arranged as a 2-dimensional array along a first direction and a second direction;
- and
- at least one metal layer, each comprising a plurality of metal wires configured to form a plurality of apertures for passing lights to the plurality of sensing elements;
- wherein a border of the plurality of sensing elements is disposed along a third direction different from the first direction and the second direction;
- and
- wherein none of a plurality of borders of the plurality of sensing elements is disposed along the first direction or the second direction.
An image sensor, comprising:
- a sensor layer, comprising a plurality of sensing elements divided into a plurality of groups, wherein the plurality of groups are arranged as a 2-dimensional array along a first direction and a second direction;
- and
- at least one metal layer, each comprising a plurality of metal wires configured to form a plurality of apertures for passing lights to the plurality of sensing elements;
- wherein the sensing elements in each of the plurality of groups are arranged as a 2-dimensional array along a third direction and a fourth direction, wherein each of the third direction and the fourth direction is different from the first direction and the second direction.
