Abstract

Methods of processing a first substrate bonded to a second substrate include moving a wire along an interface to propagate a debonding front and debond the first substrate from the second substrate. In some embodiments, the first substrate includes a thickness less than or equal to about 300 μm. In further embodiments, the wire includes a tensile strength less than a critical failure stress of the first substrate. In still further embodiments, the wire is configured to conform to a shape of the debonding front during the step of moving the wire such that one or more edges of the first substrate are debonded from the second substrate prior to a debonding of a corresponding interior portion of the first substrate from the second substrate.
