Abstract
An imaging element includes a photoelectric conversion section and a wiring layer. The photoelectric conversion section is configured to photoelectrically convert light incident from a subject. The wiring layer is provided on an opposite side of the subject with respect to the photoelectric conversion section and includes a wire connected to an element that constitutes a pixel including the photoelectric conversion section. The wire includes a plurality of wires extending long in a predetermined direction. The plurality of wires are arranged in a direction almost perpendicular to the predetermined direction in the wiring layer. The wire is provided with a protrusion protruding in a direction different from the predetermined direction.
Claims19
An imaging element, comprising:
- a photoelectric conversion section configured to photoelectrically convert light incident from a subject;
- and
- a wiring layer that is provided on a side of the photoelectric conversion section opposite the subject and includes a plurality of wires extending long in a predetermined direction and coupled to an element that constitutes a pixel including the photoelectric conversion section, the plurality of wires being arranged parallel to one another in a direction substantially perpendicular to the predetermined direction in the wiring layer, each of the plurality of wires being provided with a plurality of protrusions,
- wherein each protrusion protrudes in a direction that is perpendicular to the predetermined direction,
- wherein at least one wire of the plurality of wires has at least a first protrusion and a second protrusion in a region corresponding to one pixel in a plan view,
- wherein the first protrusion is disposed at a first side of the at least one wire in the plan view, and
- wherein the second protrusion is disposed at a second side of the at least one wire in the plan view.
An electronic apparatus, comprising:
- an imaging element, including:
- a photoelectric conversion section configured to photoelectrically convert light incident from a subject, and
