Patent ID: 8786055

Claim:
A solid-state imaging device, comprising: a semiconductor substrate configured to include a solid-state imaging element that is provided with a photoelectric conversion region, and a scribe line region that is provided along a periphery of the solid-state imaging element; a wiring layer that is formed to be layered on the semiconductor substrate, wherein the wiring layer includes a guard ring layer in a region corresponding to a region, the region being positioned between a blade region in the scribe line region and the solid-state imaging element, of the semiconductor substrate, and wherein the wiring layer and the guard ring layer include the same material; a support substrate that is formed to be layered on the wiring layer; and a groove that is provided in the semiconductor substrate between the blade region in the scribe line region and the solid-state imaging element, wherein the groove penetrates through the semiconductor substrate, wherein a depth of the groove is equal to a depth of the semiconductor substrate, wherein the groove contains a chipping prevention wall, and wherein the chipping prevention wall does not extend into the wiring layer.
