A method of processing a wafer that does not leave residue from removal of a chamfered portion. The method includes: a first modified layer forming step of applying a laser beam to an inner side adjacent to a chamfered portion formed on an outer periphery of the first wafer by focusing the laser beam and transmitting through the first wafer to form a ring-shaped modified layer; and a second modified layer forming step of applying the laser beam to a bonded surface of the first and second wafers, by focusing the laser beam and transmitting through the first wafer to form a bonding-force reducing modified layer. In the second modified layer forming step, the bonding-force reducing modified layer is connected with a bottom portion of the ring-shaped modified layer formed in the first modified layer forming step, or a ring-shaped modified layer formed after the second modified layer forming step.

METHOD FOR REUSING A SUPPORTING WAFER AND METHOD FOR MANUFACTURING CHIPS
A method for reusing a supporting wafer, which has chips or a wafer bonded thereon with an adhesive agent, by separating the supporting wafer from the chips or the wafer and thereafter removing the adhesive agent from the supporting wafer, is provided. The method includes an adhesive agent removing process including irradiating the adhesive agent remaining on the supporting wafer after separating the supporting wafer from the chips or the wafer with a laser beam to remove the adhesive agent.
