Abstract:
1. A semiconductor water in which a plurality of semiconductor circuits are formed, each of the semiconductor circuits comprising: an external terminal coupled to an external measurement circuit; a plurality of selecting wiring lines provided so as to correspond to a plurality of measuring points in the semiconductor circuit and so as to receive and transmit signals to/from the corresponding measuring points, the selecting wiring lines provided so as to electrically couple the corresponding measuring points to the external terminal; a selecting section that selects one of the selecting wiring lines, and that allows signal transmission between the corresponding measuring point and the external terminal through the selected selecting wiring line; a measurement driver that is provided between the measuring points and the external terminal; an actual operation terminal that is used when the semiconductor circuit is implemented; and a driver circuit that outputs a signal outside the semiconductor circuit via the actual operation terminal, wherein output current of the measurement driver is smaller than an output current of the driver circuit.
