Patent ID: 6900646

Claim:
In the production of a semiconductor device, a method of testing the semiconductor device comprising; a positioning step which positions said semiconductor device to be tested at a set position; a contacting step which contacts a contact electrode having a plurality of projecting contacting tips formed on a first surface of an insulating sheet of a connection part of a testing apparatus with an electrode of said semiconductor device, said plurality of projecting contacting tips being formed by etching a first conductor layer or a second conductor layer on said first conductor layer, said first conductor layer being formed on said first surface of said insulating sheet; and a signal transferring step which transfers electric signals to said electrode of said semiconductor device from said testing apparatus through said contact electrode having said plurality of projecting contacting tips and a wiring conductor connected with said contact electrode for conducting a test signal on said semiconductor device; and wherein during said contacting step and said signal transferring step, said plurality of projecting contacting tips on a single contact electrode contact with one electrode of said semiconductor device.
