    Abstract: Described methods and apparatus provide a controlled perturbation to an adhesive bond between a device wafer and a carrier wafer. The controlled perturbation, which can be mechanical, chemical, thermal, or radiative, facilitates the separation of the two wafers without damaging the device wafer. The controlled perturbation initiates a crack either within the adhesive joining the two wafers, at an interface within the adhesive layer (such as between a release layer and the adhesive), or at a wafer/adhesive interface. The crack can then be propagated using any of the foregoing methods, or combinations thereof, used to initiate the crack.

The stripping liquid is fed onto the surface (paper surface) of the plaster/paper laminate so as to infiltrate into the bonding surface between the plaster and the paper, so that the carboxylate is made present on the bonding surface. Upon stripping off the paper in the presence of the carboxylate, it is allowed to entirely separate the paper from the plaster. Upon mixing the stripping liquid and a nonionic surfactant or a water-soluble organic solvent together, further, the stripping liquid can be quickly and reliably infiltrated into the bonding surface between the plaster and the paper.
