Patent ID: 7557598

Claim:
A method of inspecting a quiescent power supply current in a semiconductor integrated circuit, the method comprising: (a) an ID information acquisition process for acquiring ID information of one of a plurality of semiconductor integrated circuits; (b) a quiescent power supply current measuring process for measuring a quiescent power supply current value of the quiescent power supply current in the one of the plurality of semiconductor integrated circuits; (c) a measurement information storing process for storing the quiescent power supply current value and the ID information in corresponding pairs; (d) repeating the processes (a) through (c) for storing a plurality of measured quiescent power supply current values for the plurality of semiconductor integrated circuits; (e) a reference value determining process for determining a reference value on the basis of the plurality of measured quiescent power supply current values stored in the memory; and (f) a defect determining process, by comparing a stored quiescent power supply current value with the reference value, for determining whether the semiconductor integrated circuit is defective or not.
