Abstract:
1. A semiconductor device wiring structure comprising: a semiconductor device having a first electrode on a first main surface and a second electrode on a second main surface that faces in an opposite direction as the first main surface; a first sheet-shaped wiring conductively connected to the first electrode of the semiconductor device; a second sheet-shaped wiring conductively connected to the second electrode of the semiconductor device, the second sheet-shaped wiring being disposed with respect to the first sheet-shaped wiring such that a current direction in the second sheet-shaped wiring is opposite to a current direction in the first sheet-shaped wiring; and a conductive substrate having a base surface with a larger width than the second sheet-shaped wiring, the conductive substrate being arranged adjacent to the first sheet-shaped wiring such that the base surface of the conductive substrate is disposed substantially parallel to the first main surface of the semiconductor device, the second sheet-shaped wiring including edges that protrude beyond corresponding edges of both of the first sheet-shaped wiring and the semiconductor device in all locations such that the second sheet-shaped wiring substantially covers the first sheet-shaped wiring and the semiconductor device in a top plan view, the edges of the second sheet-shaped wiring protruding beyond the corresponding edges of at least one of the first sheet-shaped wiring and the semiconductor device by an amount that is at least one half of a distance from the edges of the second sheet-shaped wiring to the conductive substrate.
