Patent ID: 8633596

Claim:
A semiconductor package comprising: a semiconductor device including a plurality of signal pads and a plurality of auxiliary pads which are alternatively arranged in a predetermined direction; and a package board including a plurality of signal bond fingers arranged in said predetermined direction for supplying signals to said signal pads, a plurality of first power supply voltage bond fingers arranged in said predetermined direction for supplying a first power supply voltage to said auxiliary pads, and a plurality of second power supply voltage bond fingers arranged in said predetermined direction for supplying a second power supply voltage to said auxiliary pads, said semiconductor device being mounted on said package board; wherein said signal pads are connected respectively to said signal bond fingers by first wires; said first power supply voltage bond fingers and said second power supply voltage bond fingers are connected respectively to said auxiliary pads by second wires; and said first wires are disposed between those of said second wires which are connected to said first power supply voltage bond fingers and those of said second wires which are connected to said second power supply voltage bond fingers.
