Patent ID: 6952110

Claim:
A testing apparatus for carrying out inspection of a semiconductor device to be tested by coming into contact with test electrodes of the semiconductor device, comprising: 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; 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; and a supporting member to support said contactor-supporting member, the supporting member being separable from said contactor-supporting member, wherein said testing apparatus being formed to allow positional variation between said contactor and said contactor-supporting member when said contactor units come into contact with said semiconductor device to be tested.
