    Abstract: A semiconductor element includes: a substrate having an integrated circuit; and a wire connection electrode and a bump connection electrode which are provided on a same main surface of the substrate as electrodes having a same connection function to the integrated circuit. The wire connection electrode is provided in a periphery of the main surface. The bump connection electrode is provided inside the wire connection electrode on the main surface. When a straight line dividing the main surface into two regions is determined, the wire connection electrode and the bump connection electrode are located opposite to each other with respect to the straight line.

  • Patent number: 7391114
    Abstract: A pad section serving as an electrode for external connection of a semiconductor device includes a first pad metal (61) formed in the top layer, a second pad metal (62) formed under the first pad metal (61) via an interlayer insulating film (71), and vias (63) which penetrate the interlayer insulating film (71) and electrically connect the first pad metal (61) and the second pad metal (62). The first pad metal (61) and the second pad metal (62) have edges displaced from each other so as not to be aligned with each other along the thickness direction of each layer. Thus, it is possible to reduce stress occurring on an edge of the second pad metal (62), thereby reducing damage on the interlayer insulating film (71) and so on.

  • Publication number: 20070023927
    Abstract: When an interlayer film (22) is formed to have a large thickness and an electrode pad (11) is partly or wholly led out from an active region (16), an I/O region (15) can be reduced in area. Thus, it is possible to reduce an area of a semiconductor device.
