ABSTRACT:
A device for generating voltage signals in a semiconductor device upon irradiation with a charged particle beam, wherein a circuit for converting a beam current of the irradiated charged particle beam into the voltage signals is constituted by a bipolar transistor and a load device contained in the semiconductor device, and a portion of the line pattern connected to the base of the bipolar transistor is irradiated with the charged particle beam, so that signals are generated at high speeds even by using a weak charged particle beam without permitting the device to be broken down.
