Abstract:
A performance of a semiconductor device is improved. The semiconductor device according to one embodiment includes a wire bonded to one bonding surface at a plurality of parts in an opening formed in an insulating film of a semiconductor chip. The semiconductor device includes also a sealer that seals the semiconductor chip and the wire so that the sealer is in contact with the bonding surface. The bonding surface includes a first region to which a bonding portion of the wire is bonded, a second region to which another bonding portion of the wire is bonded, and a third region between the first region and the second region. A width of the third region is smaller than a width of the first region and a width of the second region.

Claim (Index 17):
A method of manufacturing a semiconductor device comprising the steps of:\n (a) preparing a semiconductor chip having an electrode pad including a first front surface, a first back surface opposite to the first front surface, and a first bonding surface and having an insulating film including the first front surface and a first opening that exposes the first bonding surface of the electrode pad; (b) preparing a lead frame having a chip mounting portion to which the semiconductor chip is fixed and having a first lead separated from the chip mounting portion; (c) after the steps of (a) and (b), mounting the semiconductor chip onto the chip mounting portion so that the first back surface of the semiconductor chip and the chip mounting portion face each other; (d) after the step of (c), bonding a first wire to the first bonding surface of the semiconductor chip; and (e) after the step of (d), sealing the semiconductor chip and the first wire with an insulating material so that the insulating material is in contact with the first bonding surface of the electrode pad, wherein the first bonding surface is made of metal, in a plan view, the first bonding surface has a first region, a second region, and a third region between the first region and the second region, the step of (d) includes the steps of:\n (d 1 ) bonding a first bonding portion of the first wire to the first region of the first bonding surface; \n (d 2 ) after the step of (d 1 ), shaping a first middle portion of the first wire, the first middle portion being connected to the first bonding portion and extending in a first direction, so as to bridge over the third region of the first bonding surface; and \n (d 3 ) after the step of (d 2 ), bonding a second bonding portion of the first wire, the second bonding portion being connected to the first middle portion of the first wire, to the second region of the first bonding surface, \n the first middle portion of the first wire is separated from the third region, and, in a plan view, each of a width of the first region in a second direction orthogonal to the first direction and a width of the second region in the second direction is larger than a width of the third region in the second direction.
