摘要:
A wire bonding structure is provided which includes a wire having a first bonding portion and a second bonding portion. The first bonding portion is bonded to an electrode pad of a semiconductor element, whereas the second bonding portion is bonded to a pad portion of a lead. The first bonding portion includes a front bond portion, a rear bond portion, and an intermediate portion sandwiched between these two bond portions. The front bond portion and the rear bond portion are bonded to the electrode pad more strongly than the intermediate portion is. In the longitudinal direction of the wire, the second bonding portion is smaller than the first bonding portion in bonding length.
