Patent ID: 6933607

Claim:
A semiconductor device including a plurality of bump electrodes, respective surfaces of the bump electrodes being adapted for electrical connection to a first electrode elongated in length so as to extend in a direction crossing an edge of a semiconductor substrate so that the first electrode crosses the edge of the semiconductor substrate, the semiconductor device comprising: said semiconductor substrate; a plurality of electrode pads aligned in parallel in a first direction on said semiconductor substrate along the edge of said substrate; spaced apart bump electrodes being placed on each of said plurality of electrode pads so that a plurality of the spaced apart bump electrodes are placed on each of the electrode pads, said plurality of bump electrodes on each respective electrode pad being spaced apart from one another and aligned in a second direction orthogonal to said first direction, wherein no bump electrode on any given electrode pad is spaced apart from another bump electrode on said given electrode pad in said first direction; wherein in a state where respective upper surfaces of a pair of the bump electrodes on one of said electrode pads are electrically connected to the first electrode that is lengthwise extending in the direction crossing the edge of the semiconductor substrate, the first electrode crosses a spacing between said pair of bump electrodes; wherein each of the plurality of electrode pads is formed in the same shape and extends straight in the second direction; and wherein a space in the second direction between the bump electrodes formed on each of the plurality of electrode pads is smaller than a size in the second direction of each of the bump electrodes.
