Abstract:
An inspection contactor for inspecting electrical continuity of an inspected wafer by pushing probes against a predetermined location of said inspected wafer, said contactor comprising:a first silicon substrate provided on a main face thereof with said probes; a second silicon substrate located on another face of said first silicon substrate which another face is opposite to said main face of the first silicon substrate; a semiconductor circuit having a plurality of electrode pads located on said second silicon substrate; a third silicon substrate located on said second silicon substrate at a side opposite to the first silicon substrate; and a plurality of outer terminals located on a face of said third silicon substrate which face is opposite to said second silicon substrate; the number of said outer terminals being smaller than the number of said probes, and each of said plurality of electrode pads located in the semiconductor circuit being electrically connected to said probes or said outer terminals.
