Title: Potential state measuring method for internal wiring of semiconductor
Inventor: OKAYASU KATSUTOSHI
IPC: G01R31/302
Filed: 1994-12-28
Abstract: PURPOSE: To observe the potential of each wiring, including a wiring having invariant potential, by inserting a procedure for lowering the power supply voltage of an element DUT to be tested down to the ground voltage. CONSTITUTION: A test pattern generator 200 delivers a test pattern B to a DUT to be tested up to an n-th one where a stop signal D is delivered. Upon receiving the stop signal D, a charged particle beam unit projects a charged particle beam over a predetermined range of the element DUT and the secondary electrons emitted therefrom are measured. The detection signal is taken, as an image data (a), into an image data acquisition means 305A which generates an acquisition completion signal upon finishing the acquisition. Upon receiving the acquisition completion signal through a pattern holding means 204, the generator 200 lowers the power supply, drive signal voltage of the element DUT down to the ground potential and outputs a stop signal C. The charged particle beam unit receives the signal C and takes in 305B an image data (b) similarly.  Image data (a), (b) are acquired by repeating the operation and each wiring, including one having no potential variation in the power supply and drive signals, is displayed 306 as a potential contrast image.
