Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: (a) preparing a wiring substrate having a first surface having thereon a plurality of terminals and a second surface on a side opposite to the first surface, having an insulating film on the first surface, and having on the first surface, a first area obtained by opening the insulating film, a second area positioned inside of the first area in a planar view, and a third area positioned outside the first area in a planar view; (b) preparing a semiconductor chip having a first main surface having thereon a plurality of surface electrodes and a second main surface on a side opposite to the first main surface and having a bump electrode on the surface electrodes; and (c) electrically coupling the bump electrodes of the semiconductor chip and the terminals of the wiring substrate to each other via a coupling member to conduct flip chip bonding of the semiconductor chip to the first surface of the wiring substrate, wherein the wiring substrate has, in the first area thereof, the terminals and a wiring that crosses the first area and extends to both the second area and the third area, wherein the wiring has a first portion that crosses the first area and a second portion exposed from the second area or the third area to couple to some of the terminals, and wherein the terminals of the second portion have thereon the bump electrodes and the first portion has a wide-width portion having a width greater than that of the wiring.
