Abstract:
In debonding a temporarily adhesive-bonded carrier-workpiece pair by a combination of chemical and mechanical methods, solvents or chemicals are used to remove the adhesives primarily through dissolution, and a thin wire, filament, or blade is used to exert a cutting or wedging action between the carrier and workpiece. The two methods are used together during the debonding process. In the carrier-workpiece pair, the workpiece can be a semiconductor wafer that has been thinned and processed. The carrier and the workpiece are temporarily bonded using an adhesive dissolvable in a selected chemical or solvent. The chemical and mechanical debonding (CMDB) method can be carried out in solvent immersion or in solvent spray to provide high throughput debonding. The dissolved adhesives can be recycled and later reused, thus lowering the cost of the whole bonding and debonding process.

Claim (Index 16):
The method of  claim 1 , wherein\n the carrier-workpiece pair comprises a carrier wafer-device wafer pair temporarily bonded by a thermoplastic polymer adhesive, the exposing comprises spraying the carrier wafer-device wafer pair with a chemical solvent capable of dissolving the thermoplastic polymer adhesive, and the exerting comprises cutting the thermoplastic polymer adhesive with a wire or blade by moving the carrier wafer-device wafer pair and/or the wire or blade relative to each other.
