Patent ID: 7629231

Claim:
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) vacuuming and holding an upper face of a first semiconductor chip of the plurality to be unstuck from the adhesive tape by a first suction force with a vacuuming collet to unstick the first semiconductor chip from the adhesive tape; and (d) after the step (c), vacuuming and holding the upper face of the first semiconductor chip by the first suction force to transport the first semiconductor chip to a chip mounting position, and, after said transporting, vacuuming and holding the upper face of the first semiconductor chip by a second suction force, smaller than the first suction force, with the vacuuming collet for mounting and die-bonding of the lower face of the first semiconductor chip to a chip mounting area, wherein the first suction force is a suction force sufficient to unstick the first semiconductor chip from the adhesive tape, and the second suction force is a suction force sufficient to prevent the first semiconductor chip from dropping from the vacuuming collet.
