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 4):
The expansion method according to  claim 1 , wherein expansion of the dicing tape is performed by applying an external force to the dicing tape, and an external force applied to the dicing tape in the step (IIC) is greater than an external force applied to the dicing tape in the step (IIA).
