Abstract:
A semiconductor device includes a semiconductor chip, a first substrate, and a second substrate. The first substrate includes a plurality of wires and a plurality of first electrodes, each first electrode being connected with each wire. The second substrate includes the semiconductor chip that is mounted thereon, and a plurality of second electrodes with, each second electrode being connected with the each first electrode of the first substrate. The widths of the wires of the first substrate are different depending on the lengths of the wires. By changing the widths of the wires depending on their lengths, it is possible to reduce variation in stiffness of the electrodes and vicinities of electrodes, whereby variation in ultrasonic bonding strength can be reduced.
