ABSTRACT:
A connecting state of a signal terminal provided in a semiconductor device is confirmed by externally applying a voltage through a resistor to the signal terminal and detecting a voltage value range in which a voltage value measured at the signal terminal falls. Although the number of measurements of voltage value at the signal terminals to be tested is increased compared with the conventional method, the time necessary for each measurement is very short and it is possible to substantially reduce the total test time.
