Abstract:
1. A semiconductor device comprising: a semiconductor integrated circuit board; a semiconductor integrated circuit mounted on the semiconductor integrated circuit board; pads which are disposed on the semiconductor integrated circuit; and pads which are disposed on the semiconductor integrated circuit board and which are connected to the pads disposed on the semiconductor integrated circuit through bonding wires, wherein the bonding wires include, electric-power bonding wires, ground bonding wires, signal bonding wires and at least one stub wiring bonding wire, each of the electric-power bonding wires configured to connect an electric-power pad disposed on the semiconductor integrated circuit board to an electric-power ring pad disposed on a periphery of the semiconductor integrated circuit, the ground bonding wires configured to connect a ground pad disposed on the semiconductor integrated circuit board to a ground ring pad disposed on a periphery of the semiconductor integrated circuit, the signal bonding wires configured to connect a signal pad disposed on the semiconductor integrated circuit board to a signal pad disposed on the semiconductor integrated circuit, and the stub wiring bonding wire disposed on at least one of corner areas of the semiconductor integrated circuit, configured to connect an electric-power pad disposed on the semiconductor integrated circuit to a pad which is not electrically connected to any other electric circuit (non-connected pad) and which is disposed on the semiconductor integrated circuit board.
