    摘要: In this semiconductor device, the through-hole is formed in the substrate, and is located under the conductive pattern. The insulating layer is located at the bottom surface of the through-hole. The conductive pattern is located on one surface side of the substrate. The opening pattern is formed in the insulating layer which is located between the through-hole and the conductive pattern, where the distance r3 from the circumference of the opening pattern to the central axis of the through-hole is smaller than the distance r1 in the through-hole. By providing the opening pattern, the conductive pattern is exposed at the bottom surface of the through-hole. The bump is located on the back surface side of the substrate, and is formed integrally with the through-electrode.
