Abstract

In a pin contact test, a voltage across an external pin is measured by setting a voltage to be supplied to the power supply nodes in input protection circuits in their respective chips at a prescribed amount by means of voltage control circuits and by supplying a prescribed constant current to external pin. Based on the measurement results, a pin contact failure in chips can be detected.
