Abstract
A single-step bumping/bonding method for forming a semiconductor package of two electronic substrates electrically connected together by solder bumps. In the method, a first electronic substrate is provided equipped with a first plurality of conductive pads formed in an insulating material layer, the plurality of conductive pads each having an aperture formed therethrough for receiving a solder material when the first electronic substrate is positioned juxtaposed to a second electronic substrate equipped with a second plurality of conductive pads such that solder bumps may be formed bonding the first plurality of conductive pads to the second plurality of conductive pads. One of the two electronic substrates may be a silicon wafer, while the other may be a printed circuit board or a silicon wafer.
