Abstract:
1. An inspection device for inspecting electric characteristics of a semiconductor integrated circuit having one external electrode and the other external electrode on two faces thereof, said two faces being opposite to each other, wherein an inspection circuit board and an inspection-use semiconductor integrated circuit are arranged facing each other; the inspection circuit board has a first electrode; the inspection-use semiconductor integrated circuit has an identical structure to that of another semiconductor integrated circuit stacked on the semiconductor integrated circuit by a package-on-package technique and at the same time, includes an inspection-use external electrode on a face thereof facing the inspection circuit board; a measuring device is connected to the inspection circuit board; a holding part holding the semiconductor integrated circuit is formed between the inspection circuit board and the inspection-use semiconductor integrated circuit; a first conductive contact making contact with the first electrode of the inspection circuit board and the one external electrode of the semiconductor integrated circuit facing the inspection circuit board to electrically connect these electrodes is arranged in a fixed member; a second conductive contact making contact with the inspection-use external electrode of the inspection-use semiconductor integrated circuit and the other external electrode of the semiconductor integrated circuit facing the inspection-use semiconductor integrated circuit to electrically connect these electrodes is arranged in a movable member; the inspection-use semiconductor integrated circuit is arranged in the movable member; and the movable member is movable to a contacting position at which the second conductive contact makes contact with the other external electrode of the semiconductor integrated circuit and to a separating position at which the second conductive contact separates from the other external electrode.
