Semiconductor device and method of visual inspection and apparatus for visual inspection










Image Number 6 for United States Patent #8211718.

A semiconductor device having the structure, which is adopted for the highly precise visual inspection with a lower cost, is achieved. A semiconductor device is a semiconductor device having a region for forming an electric circuit, and includes seal rings provided in an interconnect layer and surrounding the region for forming an electric circuit, and a dummy metal via provided in the interconnect layer and located outside of the seal rings. In a cross section perpendicular to an elongating direction of the seal ring, the width of the dummy metal via is smaller than the width of the seal ring.
