Patent ID: 7404511

Claim:
A semiconductor device manufacturing apparatus, comprising: a semiconductor wafer substrate configured to include a terminal unit formed from at least two electrically separated terminals overlying a surface of the semiconductor wafer substrate, said at least two electrically separated terminals being connected to a device circuit, said semiconductor wafer substrate including an insulation layer having an opening on the terminal unit; a substrate holding section configured to hold the semiconductor wafer substrate; a discharge mechanism operative to discharge a liquid drop of metal paste from one of a plurality of discharge nozzles toward a surface of the semiconductor wafer substrate, wherein each discharge nozzle is configured to discharge a different total volume of liquid drop; a driving mechanism configured to move at least one of the substrate holding section and the discharge nozzle; a control section operative to control the discharge and driving mechanisms to selectively coat the opening overlying the terminal unit to be electrically connected with the metal paste such that at least two previously electrically separated terminals overlying the surface of the semiconductor wafer substrate are electrically connected; at least two types of discharge mechanisms; and at least two metal paste containers assigned to the at least two types of discharge mechanisms, respectively, the metal paste stored in said at least two metal paste containers having different electronic resistances from each other.
