Patent ID: 8183142

Claim:
A method of manufacturing a semiconductor device comprising the steps of: (a) forming semiconductor elements over a main surface of a semiconductor substrate of substantially rectangular shape; (b) after step (a), forming a first insulating film over the main surface of the semiconductor substrate; (c) forming a first conductive film over the first insulating film; (d) forming pad electrodes and a wiring layer by patterning the first conductive film; (e) after step (d), forming a second insulating film over the main surface of the semiconductor substrate; (f) making openings in the second insulating film to expose surfaces of the pad electrodes; and (g) forming bump electrodes of substantially rectangular shape over the second insulating film and corresponding openings so as to be disposed directly over the wiring layer in a plan view, wherein each of the pad electrodes is of smaller area in the plan view than the corresponding bump electrode, wherein the bump electrodes are arranged at predetermined intervals in a first direction which is along a long side of the semiconductor substrate, and wherein each of the bump electrodes is configured such that a long side thereof extends in a second direction which is along a short side of the semiconductor substrate.
