Patent ID: 7679174

Claim:
A semiconductor device, comprising: a circuit board including a first main surface having a first wiring network formed thereon, a second main surface opposite the first main surface having a second wiring network formed thereon, and a curved portion provided in at least one side of an external shape thereof; a semiconductor elements mounted on at least one of the first and second main surfaces of the circuit board, having electrode pads; and bonding wires electrically connecting the first or second wiring network and the electrode pads of the semiconductor element, wherein a distance from the side including the curved portion of the circuit board to the first wiring network is larger than a distance from at least one of the other sides of the circuit board to the first wiring network, and a distance from the side including the curved portion of the circuit board to the second wiring network is larger than a distance from at least one of the other sides of the circuit board to the second wiring network.
