Abstract:
A semiconductor device manufacturing apparatus for joining a semiconductor pellet to a package using a solder, the semiconductor pellet having an electrode pad on one surface side thereof and an electrically conductive member extending from the electrode pad to another surface side, which is opposite the one surface side, comprising:a collet having a surface with an electrode terminal, wherein the collet is movable so that the electrode terminal comes in contact with the electrode pad on the semiconductor pellet when joining the semiconductor pellet to the package; andan electric pulse source that supplies an electric pulse to the electrode terminal,wherein the electric pulse is supplied to the electrode pad and to the electrically conductive member through the electrode terminal, the electric pulse supplied to the electrically conductive member conducts through the solder interposed between the electrically conductive member and the package and melts the solder to join the semiconductor pellet to the package, while maintaining the semiconductor pellet to a temperature lower than an actual use temperature of the semiconductor pellet.
