Patent ID: 8003495

Claim:
A method for manufacturing a semiconductor integrated circuit device, comprising the steps of: (a) supplying a plurality of chips to a chip pick-up section of a chip treating apparatus; (b) in a state in which a surface of a first chip out of the chips supplied to the pick-up section is vacuum-chucked to a lower surface of a rubber chip of a chucking collet, conveying the first chip toward a die bonding section of the chip treating apparatus; (c) after the step (b), causing a back surface side of the first chip to land onto an upper surface of a wiring substrate placed in the die bonding section of the chip treating apparatus in a state in which the surface of the first chip is held by physical chucking between it and the lower surface of the rubber chip; and (d) after the step (c), pressing the surface of the first chip downward by the lower surface of the rubber chip, thereby fixing the first chip to the upper surface of the wiring substrate through an adhesive layer formed between the back surface of the first chip and the upper surface of the wiring substrate.
