Patent ID: 7598100

Claim:
A manufacturing method of a semiconductor integrated circuit device comprising the steps of: (a) preparing a semiconductor wafer on which a plurality of chip regions are defined, a semiconductor integrated circuit is formed in each of the plurality of chip regions, and a plurality of first electrodes electrically connected to the semiconductor integrated circuit are formed on a main surface; (b) preparing a first card including: a first wiring substrate having a first wiring formed thereon; a first sheet on which a plurality of contact terminals for contacting with the plurality of first electrodes and a second wiring electrically connected to the plurality of contact terminals are formed, the second wiring is electrically connected to the first wiring, and tips of the plurality of contact terminals are held to the first wiring substrate, opposing to the main surface of the semiconductor wafer; a plurality of pogo pins in contact with the first wiring substrate from a second surface on the other side of a first surface on which the first sheet is attached, the pogo pins transmitting an electric signal to each of the plurality of contact terminals; a bonding ring which holds a first region in the first sheet in which the plurality of contact terminals are formed, while separating the first region from the first substrate and applying tensile forces; a pressing mechanism which presses the first region in the first sheet from a rear surface thereof; and a first fixing substrate which fixes the first wiring substrate from a side of the first surface; and (c) performing electrical inspection of the semiconductor integrated circuit by contacting the tips of the plurality of contact terminals with the plurality of first electrodes, wherein each of the tips of the plurality of contact terminals is disposed on the main surface of the first sheet, so as to oppose to corresponding one of the plurality of first electrodes, and a second region surrounding the first region in the first sheet is held to the first substrate in an unstrained state.
