Abstract:
1. A semiconductor integrated circuit device, comprising: a rectangular shaped semiconductor substrate including an active region in which one or more circuits are formed; a metal wiring layer formed on or over the semiconductor substrate, wherein the semiconductor substrate is a silicon substrate; a passivation layer covering the metal wiring layer; and four corner non-wiring regions provided at a surface of the semiconductor integrated circuit device, respectively, at each of four corners of the semiconductor integrated circuit device, where no portion of the metal wiring layer is formed on the four corner non-wiring regions, wherein each of the corner non-wiring regions is a triangular region enclosed by a first line connecting the corner of the semiconductor integrated circuit device and a first point located on an edge extending from the corner, a second line connecting the corner and a second point located on another edge extending from the corner, and a third line connecting the first point and the second point, with no portion of the metal wiring layer inside the triangular region.
