There is reduced the difference in inductance between bonding wires to be coupled to two semiconductor chips stacked one over another. A semiconductor device includes external terminals, lower and upper semiconductor chips, and first and second bonding wires. The lower semiconductor chip has first bonding pads, and the upper semiconductor chip has second bonding pads. The first bonding wire couples the first bonding pad of the lower semiconductor chip and the external terminal, and the second bonding wire couples the second bonding pad of the upper semiconductor chip and the external terminal. The diameter of the second bonding wire is larger than the diameter of the first bonding wire. |
