Abstract:
1. A fabrication method of a semiconductor device comprising the steps of: (a) preparing a semiconductor wafer in which a principal surface thereof is partitioned into a plurality of chip areas by parting areas, an integrated circuit is formed in each of the chip areas, and an adhesive tape is stuck to a rear surface of the semiconductor wafer; (b) cutting the semiconductor wafer along the parting areas to divide the semiconductor wafer into a plurality of semiconductor chips, and holding the semiconductor chips by the adhesive tape; (c) horizontally applying a first tension to an adhesive face of the adhesive tape with the semiconductor chips stuck thereto and plunging up a first semiconductor chip of the plurality to be unstuck from the adhesive tape with a plunge-up jig, and vacuuming and holding an upper face of the first semiconductor chip by a first predetermined suction force with a vacuuming collet for the purpose of unsticking the first semiconductor chip from the adhesive tape; and (d) after the first semiconductor chip unsticks from the adhesive tape, vacuuming and holding the upper face of the first semiconductor chip with the vacuuming collet, and die-bonding a lower face of the first semiconductor chip to a chip mounting area, wherein, during the die-bonding in the step (d), the vacuuming and holding are performed by a second predetermined suction force smaller than the first predetermined suction force, wherein a changeover from the first predetermined suction force to the second predetermined suction force is carried out before the die-bonding, and where the changeover from the first predetermined suction force to the second predetermined suction force is carried out immediately after the first semiconductor chip is transported to the chip mounting area.
