Abstract:
1. A method of producing a semiconductor device comprising the steps of: forming a plurality of semiconductor devices on a wafer; contacting a plurality of contact terminals to electrodes of said semiconductor devices and testing electrical characteristics of said semiconductor devices; and detaching said semiconductor devices from said wafer, wherein said step of testing electrical characteristics of said semiconductor devices includes a step of exchanging an electrical signal between said semiconductor devices and a tester circuit through said contact terminals and wires, wherein the contact terminals are formed by using a wafer with an etched hole as a mold and are made of conductive materials. wherein said wires and said contact terminals are formed separately and both are electrically connected to form a multilayer film, wherein said multilayer film has an insulation layer, wherein said wires are formed on said insulation layer, and wherein a ground layer is formed on a reverse side of said wires formed on said insulation layer.
