Abstract
A workpiece processing apparatus that prevents a processing capability of a processing apparatus from deteriorating due to a peeling unit that peels a protective sheet from a workpiece. A workpiece processing apparatus includes an affixing unit that affixes a dicing tape to a workpiece and a dicing frame, and a plurality of peeling units that peel a protective sheet previously affixed to the workpiece from the workpiece integrated with the dicing frame via the dicing tape.
Claims4
A workpiece processing apparatus comprising:
- an affixing unit that affixes a dicing tape to a workpiece and a dicing frame;
- a plurality of peeling units that peel a protective sheet previously affixed to the workpiece from the workpiece integrated with the dicing frame via the dicing tape,
- each of the peeling units includes a bonding section that bonds a release tape to the protective sheet and a peeling table that is movable relative to the bonding section with the workpiece placed thereon,
- each of the peeling units is configured to be able to adjust a temperature of the bonding section and the peeling table to be a temperature suitable for processing of a workpiece to be then processed at a standby time, and
- the type of the release tape differs between the peeling units depending on the type of the workpiece.

A workpiece processing apparatus for processing a wafer comprising:
- an affixing unit having a sliding affixing table configured to hold a frame unit including a dicing frame and the wafer having a protective sheet attached, said affixing unit configured to affix a dicing tape to the wafer and the dicing frame;
- a first peeling unit having a first sliding peeling table configured to hold the frame unit, said first peeling unit having a first heat stamp configured to bond a first release tape to the protective sheet, and a first table heater configured to heat said first sliding peeling table to a first temperature suitable for peeling the protective sheet;
- a second peeling unit having a second sliding peeling table configured to hold the frame unit, said second peeling unit having a second heat stamp configured to bond a second release tape to the protective sheet, and a second table heater configured to heat said second sliding peeling table to a second temperature suitable for peeling the protective sheet;
- a BCP unit having a sliding BPC table;
- and
- a conveyance unit positioned between said affixing unit, said first peeling unit, said second peeling unit, and said BPC unit, said conveyance unit configured to convey the frame unit selectively between said first peeling unit and said second peeling unit,
- whereby conveying the frame unit selectively between said first peeling unit and said second peeling unit prevents a processing capability of the workpiece processing apparatus from deteriorating improving efficiency.
