Patent ID: 7508073

Claim:
A wiring board, comprising: an insulating substrate; a plurality of conductive wirings provided on the insulating substrate so as to be aligned with a semiconductor mounting region where a semiconductor chip is to be mounted; bump electrodes provided on the respective conductive wirings; and external connection terminals connected to the conductive wiring so as to be connected with an external device, wherein the bump electrodes comprise first bump electrodes for mounting the semiconductor chip and second bump electrodes for adjusting height of the first bump electrodes, the first bump electrodes and the second bump electrodes are formed by plating, at least one of the second bump electrodes is provided at a region of the plurality of conductive wirings outside the semiconductor mounting region so as to be located between the semiconductor mounting region and the external connection terminals, and the second bump, electrodes protrude from the surface of the conductive wirings in a height direction of the semiconductor chip.
