Patent ID: 7656019

Claim:
A semiconductor device comprising: a wiring board having a first surface; a semiconductor chip mounted over the first surface of the wiring board, the semiconductor chip having a main surface and a plurality of electrode pads including first electrode pads and second electrode pads formed over the main surface of the semiconductor chip along a first side of the semiconductor chip; a plurality of first connecting portions formed over the first surface of the wiring board and arranged along the first side of the semiconductor chip; a plurality of second connecting portions formed over the first surface of the wiring board and arranged along the first side of the semiconductor chip at positions more distant from the first side of the semiconductor chip than the first connecting portions; a plurality of first wiring lines formed over the first surface of the wiring board, each connected to a corresponding first connecting portion of the plurality of first connecting portions, each of the plurality of first wiring lines having a width which is less than a width of the corresponding first connecting portion and extending from the corresponding first connecting portion toward the first side of the semiconductor chip; a plurality of second wiring lines formed over the first surface of the wiring board, each connected to a corresponding second connecting portion of the plurality of second connecting portions, each of the plurality of second wiring lines having a width which is less than a width of the corresponding second connecting portion and extending from the corresponding second connecting portion toward a peripheral portion of the first surface of the wiring board, in a direction away from the first side of the main surface of the semiconductor chip; a plurality of bonding wires connecting the first and second electrode pads with the first and second connecting portions, respectively; and a resin sealing body for sealing the semiconductor chip and the bonding wires.
