Abstract
An interposer to be mounted with an integrated circuit to be a test object is provided with a switch and a probe to detect an electric current corresponding to individual terminals of the integrated circuit. A test pattern signal is then inputted to the integrated circuit through a test substrate as a switch that is connected to a power supply terminal of the integrated circuit and that is turned off. If the integrated circuit normally operates and the current values of all the terminals of the integrated circuit are within a tolerance, the power supply terminal connected to the turned-off switch is identified as a terminal that may be removed.
