Abstract:
1. A method for manufacturing a semiconductor integrated circuit device, comprising the steps of: (a) supplying a plurality of chips divided in individual chip regions while being arranged substantially in their original two-dimensional layout upon a wafer, to a chip treating apparatus with their back surfaces fixed to an adhesive tape; and (b) vacuum-chucking a surface of a first chip out of the chips with a chucking collet and peeling the adhesive tape from the back surface of the first chip in a state in which the adhesive tape over the back surface of the first chip is vacuum-chucked to an upper surface of a lower base; the step (b) comprising a following sub-step of: (b1) monitoring a bent state of the first chip before complete separation of the first chip from the adhesive tape by measuring the flow rate of a vacuum chucking system of the chucking collet.
