Abstract:
1. A semiconductor device comprising a semiconductor element having electrodes, a metal member, wires that electrically connect the semiconductor element and the metal member, and/or electrodes within the semiconductor element, wherein the wires constitute at least a first wire loop and a second wire loop, the first wire loop is bonded at one end to a first bonding point by ball bonding and at the other end to a second bonding point, the first wire loop having a flat part formed at the first bonding point by flattening a part of a ball part and a loop of the wire drawn from the ball part toward an opposite side of the second bonding point, and the second wire loop is bonded at one end to a third bonding point by ball compression bonding and at the other end to the flat part of the first wire loop at the first bonding point, the wire bonding at the third bonding point and at a flat part of the first wire loop at the first bonding point being compression bonded, a second ball formed by the melting of the wire at the third bonding point, a loop of the wire drawn from the second ball toward an opposite direction of the first bonding point with the loop extending from the second ball over and onto the second ball and being further compression bonded to the second ball, the wire being drawn toward the first bonding point, and bonded to the first bonding point.
