A method of dividing a wafer having a plurality of dividing lines formed on the front surface in a lattice pattern and function elements formed in a plurality of areas sectioned by the plurality of dividing lines into individual chips, along the dividing lines, the method comprising the steps of forming a deteriorated layer by applying a laser beam capable of passing through the wafer along the dividing lines; expanding the support tape affixed to the wafer to divide the wafer into individual chips along the dividing lines where the deteriorated layer has been formed and to form a space between adjacent chips; and applying an external stimulus to an area, to which the wafer is affixed, of the support tape in the above state to cure the adhesive layer to maintain the space between adjacent chips.
