Abstract:
To improve the joining strength between semiconductor chips. In a semiconductor device, a first semiconductor chip includes a first joining surface including a first insulating layer, a plurality of first pads to which a first inner layer circuit insulated by the first insulating layer is electrically connected, and a linear first metal layer arranged on an outside of the plurality of first pads. A second semiconductor chip includes a second joining surface joined to the first joining surface, the second joining surface including a second insulating layer, a plurality of second pads that are arranged in positions facing the first pads and to which a second inner layer circuit insulated by the second insulating layer is electrically connected, and a linear second metal layer arranged in a position facing the first metal layer. A width of the first metal layer and the second metal layer is a width based on a joining strength between the first insulating layer and the second insulating layer and a joining strength between the first metal layer and the second metal layer in an area from an end portion of the first semiconductor chip to the first pad.

Claim (Index 10):
A light detecting device, comprising:\n a first substrate including a plurality of pixels in a pixel array and a first wiring layer, wherein the first wiring layer includes a first pad and a first guard ring; a second substrate including a signal processing region and a second wiring layer, wherein the plurality of pixels outputs a plurality of pixel signals to the signal processing region, wherein the second wiring layer includes a second pad and a second guard ring, wherein the first pad is joined to the second pad, wherein the first pad and the second pad are electrically connected to each other, wherein the first pad is electrically connected to the first substrate, wherein the second pad is electrically connected to the second substrate, wherein the first guard ring and the second guard ring are disposed outside of the pixel array, and wherein the first guard ring is joined to the second guard ring.
