Abstract:
A semiconductor device comprisinga semiconductor substrate having a center area where an integrated circuit is to be formed and a peripheral area surrounding the center area; a first wiring pattern formed on the substrate in the center area, the first wiring pattern including a pad pattern; a second wiring pattern, which is formed of the same material as the first wiring pattern formed in the peripheral area along an edge of the semiconductor substrate; a third wiring pattern, which is formed of the same material as the first wiring pattern and is connected to the second wiring pattern, formed in the peripheral area, the third wiring pattern encompassing a part of the center area; and an insulating layer formed above the semiconductor substrate, the insulating layer being formed outside the second and third wiring pattern but not being formed over the second and third wiring pattern, wherein an edge of the insulating layer is located on the pad pattern, which is adjacent to the second wiring pattern.
