Claim:
1. An electric current application method of applying electric current to a semiconductor that includes: a first electric current carrying part that conducts a first electric current, a second electric current carrying part that is electrically connected with the first electric current carrying part and that conducts a second electric current, and a contact region that inputs a control signal, the method comprising: a residual electricity eliminating step of contacting a first electrode of an electric current applying device to the first electric current carrying part, and eliminating residual electricity remaining in the first electric current carrying part and the second electric current carrying part; a contacting step of contacting a signal electrode of the electric current applying device with the contact region, after the residual electricity eliminating step; a main electric current conducting step of contacting, from the same side as the first electrode, a second electrode of the electric current applying device to the second electric current carrying part, conducting the first electric current and the second electric current, and inputting a control signal, after the contacting step; a second electrode separating step of separating the second electrode from the second electric current carrying part, after the main electric current conducting step; and a first electrode separating step of separating the first electrode from the first electric current carrying part, after the second electrode separating step.
