Debonding temporarily bonded semiconductor wafers

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.
