Abstract
A solid-state image capturing device is provided, and in a pixel section in the center of a chip where a plurality of light receiving elements are arranged in two dimensions, an on-chip lens for focusing incident light is provided on each of the plurality of light receiving elements in a corresponding manner; and a dummy pattern made of a material for the on-chip lens is provided on a peripheral circuit section on an outer circumference side of the chip in order to improve the heat-resisting property at the time of reflow soldering.
Claims11
A solid-state image capturing device, wherein:
- in a pixel section in the center of a chip where a plurality of light receiving elements are arranged in two dimensions, an on-chip lens for focusing incident light is provided on each of the plurality of light receiving elements in a corresponding manner;
- and
- a dummy pattern made of a same material as that of the on-chip lens is provided on an outer circumference edge of a protective layer on a peripheral circuit section on an outer circumference side of the chip in order to improve the heat-resisting property of the protective layer at the time of reflow soldering, wherein the dummy layer is farmed in the same layer as the on-chip lens.
