A method comprises forming semiconductor flip chip interconnects where the flip chip comprises a wafer and a substrate having electrical connecting pads and electrically conductive posts operatively associated with the pads and extending away from the pads to terminate in distal ends. Solder bumping the distal ends by injection molding solder onto the distal ends produces a solder bumped substrate. Another embodiment comprises providing the substrate having the posts on the pads with a mask having a plurality of through hole reservoirs and aligning the reservoirs in the mask to be substantially concentric with the distal ends. This is followed by injecting liquid solder into the reservoirs to provide a volume of liquid solder on the distal ends, cooling the liquid solder in the reservoirs to solidify the solder, removing the mask to expose the solidified solder after the cooling and thereby provide a solder bumped substrate. This is followed by positioning the solder bumped substrate on a wafer in a manner that leaves a gap between the wafer and the substrate. The wafer has electrically conductive sites on the surface for soldering to the posts. Abutting the sites and the solder bumped posts followed by heating the solder to its liquidus temperature joins the wafer and substrate, after which, the gap is optionally filled with a material comprising an underfill.
