Claim 0:
1. A processing method of a workpiece, comprising:
a positioning step of positioning an annular frame that has an opening to receive the workpiece therein on a heat table with a first heat source included therein;
a thermocompression sheet placing step of placing a thermocompression bonding sheet on the annular frame;
an integration step of heating and compression bonding the thermocompression bonding sheet to the annular frame 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, in the integration step, the thermocompression bonding sheet is pressed against the annular frame that has been heated by the heat table, by a heat roller with a second heat source included therein while being heated by the heat roller, thereby the thermocompression bonding sheet is fixed to the annular frame while the thermocompression bonding sheet is being heated from both an upper surface thereof and from a lower surface thereof.
