Zusammenfassung:Methods and apparatus to inhibit cracks and delaminations in a semiconductor chip solder bump and to reduce pad parasitic capacitance are disclosed. In one aspect, a method of manufacturing is provided that includes forming a first insulating layer over plural conductor pads of a semiconductor chip and forming an opening over each of the conductor pads. An individual solder structure is coupled to the insulating layer. The solder structure has a projection in each of the openings and in electrical contact with one of the plural conductor pads.
