Abstract:
1. A semiconductor device comprising: a semiconductor chip connected to a first electrode terminal; a second electrode terminal separated from the first electrode terminal; and a connector that comprises first through third structural parts, wherein the first structural part is connected to an electrode of the semiconductor chip via a first connecting part thereof; the third structural part is connected to a second electrode terminal via a second connecting part thereof; the second structural part interconnects the first and third structural parts; and a structural non-uniformity is provided on at least one of the first through third structural parts, wherein the structural non-uniformity comprises a plurality of holes each having a quadrangle, round, or elliptic shape and extending inwardly of a structural part of the connector, a connecting layer is provided intermediate of the structural parts and the electrode to which the structural part is connected, and the connecting layer extends inwardly of the holes to a distance of up to one half the depth of the holes, and the structural part has a generally rectangular shape having a surface facing the electrode to which the structural part is joined through the connecting layer, the surface having a center, and the holes are disposed to be generally symmetric about the center.
