Abstract:
1. A manufacturing method for a semiconductor device having a process that prepares a wafer on which semiconductor elements are formed having electrical circuits and electrode pads that are electrically connected to said electrical circuits, a process that forms wiring for the purpose of connecting external connecting terminals and the above-mentioned electrode pads on the above-mentioned semiconductor elements, a process that connects preformed conductive supporting posts to prescribed positions of the above-mentioned wiring, said supporting posts comprising solder, a process that forms resin so that the tips of the above-mention conductive supporting posts on the above-mentioned semiconductor element are exposed, a process that forms external connecting terminals on the tips of the above-mentioned conductive supporting posts, and a process that produces semiconductor devices on which external connecting terminals are formed by dicing the above-mentioned wafer, wherein the above-mentioned conductive supporting posts are formed by means of nearly spherical copper balls and solder that covers the surface of said copper balls.
