An adhesive tape joined to a wafer is irradiated with ultraviolet rays via diodes. Simultaneously, a heater heats the adhesive tape to a preset temperature. Consequently, an ultraviolet reaction with the diodes and an infrared reaction with the heater may ensure promotion of a polymerization reaction, which results in cure of an adhesive that is not curable with only ultraviolet rays. As a result, an adhesive force of the adhesion tape may sufficiently be reduced. After ultraviolet irradiation via the diodes and heating with the heater, a separation mechanism separates the adhesive tape from the wafer. Therefore, accurate separation may be realized of the adhesive tape joined to the wafer.
