Claim 8:
9. A processing method of a workpiece, comprising:
an integration step of heating and compression bonding a thermocompression bonding sheet to an annular frame that has an opening to receive the workpiece therein and to the workpiece received in the opening, thereby the annular frame and the workpiece are integrated via the thermocompression bonding sheet; and
a processing step of processing the workpiece integrated with the annular frame via the thermocompression bonding sheet,
wherein the integration step comprises:
a frame fixing step in which the thermocompression bonding sheet is pressed against the annular frame that has been heated by a heat table with a heat source included therein, by a heat roller with a heat source included therein while being heated by the heat roller, thereby fixing thermocompression bonding sheet is fixed to the annular frame; and
a workpiece fixing step of fixing the workpiece to the thermocompression bonding sheet with the frame affixed thereon,

wherein the workpiece fixing step is performed after the frame fixing step.
