Claim 5:
6. The processing apparatus according to claim 1, wherein
the tape pressure bonding unit includes an upper chamber disposed over the wafer table, a lower chamber in which the wafer table is housed, a raising-lowering mechanism that raises and lowers the upper chamber and generates a closed state in which the upper chamber is brought into contact with the lower chamber and an opened state in which the upper chamber is separated from the lower chamber, a vacuum part that sets the upper chamber and the lower chamber to a vacuum state in the closed state, and an opening-to-atmosphere part that opens the upper chamber and the lower chamber to atmosphere, and
in a state in which the tape of the tape-attached frame is positioned to the one surface of the wafer supported by the wafer table, the upper chamber and the lower chamber are set to a vacuum state while the raising-lowering mechanism is actuated to keep the closed state, and pressure bonding of the tape of the tape-attached frame to the one surface of the wafer is executed by a pressing roller disposed in the upper chamber.
