Abstract:
1. A method of manufacturing a semiconductor device, comprising: forming process for forming a semiconductor device on a major surface of a wafer; and testing process for testing defect of the semiconductor device formed on said wafer, said testing process comprising a step conducted by bringing a testing apparatus into contact with test electrodes of said semiconductor device, said testing apparatus having a plurality of contactor units having a plurality of contactors comprising a plurality of probes that come into contact with the test electrodes of the semiconductor device to be tested and secondary electrodes electrically connected to said probes and disposed on a surface opposite to said probes; a substrate on which electrodes electrically communicated to said contactor units by a conducting device are formed; and a contactor-supporting member for accommodating said plurality of contactor units and supporting said contactor units in a region containing circumferential ends of said contactor units to provide a variable distance between the contactor units and the contactor-supporting member; said testing apparatus being formed to allow positional variation between said contactors and said contactor-supporting member when said contactor units come into contact with said semiconductor device to be tested.
