Abstract:
An embodiment of the present invention relates to an expansion method comprising: a step (I) of preparing a laminate having a semiconductor wafer in which modified sections have been formed along intended cutting lines, a die bonding film and a dicing tape, a step (IIA) of expanding the dicing tape with the laminate in a cooled state, a step (IIB) of loosening the expanded dicing tape, and a step (IIC) of expanding the dicing tape with the laminate in a cooled state, dividing the semiconductor wafer and the die bonding film into chips along the intended cutting lines, and widening the spaces between the chips.

Claim (Index 2):
An expansion method according to  claim 1  comprising:\n a step (Ia) of preparing a laminate having a semiconductor wafer in which modified sections have been formed along intended cutting lines, a die bonding film, a dicing tape and a frame, \n a step (Ib) of supplying the laminate to a height-adjustable expansion stage of an expansion apparatus comprising the expansion stage and a fastening member capable of fastening the frame, \n a step (Ic) of fastening the frame using the fastening member, a step (IIa) of raising the expansion stage and expanding the dicing tape with the laminate in a cooled state, \n a step (IIb) of lowering the raised expansion stage and loosening the expanded dicing tape, and \n a step (IIc) of raising the expansion stage and expanding the dicing tape with the laminate in a cooled state, dividing the semiconductor wafer and the die bonding film into chips along the intended cutting lines, and widening spaces between the chips.
