Abstract

PURPOSE:To avoid the breakdown of probes due to the leakage of falling down dust between the probes or any falling down matters by a method wherein the vision field region of an inspection device is covered with a transparent glass or plastic plate to protect the probes. CONSTITUTION:A semiconductor device 7 in a wafer state is fixed on a stage 6. Next, the stage 6 is lifted so that electrode pads 8 of the semiconductor device 7 may be brought into contact with probes 4 to be electrically connected with one another. When the electrode pads 8 are electrically connected with the probes 4, the electric signals from an outer measuring instrument are transmitted to the electric pads 8 through the intermediary of the electrode 3, the wiring 2 and the probes 4 of the inspection device of the semiconductor device 7 so as to inspect the electric characteristics of the semiconductor device 7. In such a constitution, the vision field region of a printed board 1 on the opposite side of the surface whereon the probes 4 on the printed board 1 are fixed is covered with a transparent plate 10 made of glass or plastic so as to to protect the probes 4.
