Claim Text:
1. System for stripping a product substrate off a carrier substrate connected to the product substrate by a bonding layer, said bonding layer fixing the product substrate to the carrier substrate, wherein said system comprises: a flexible film including: a film frame fixed to the flexible film at the attachment surface section, wherein surfaces of the film frame and the flexible film define a recess that serves as a solvent reservoir for receiving (i) the bonding layer and (ii) a solvent for dissolving the bonding layer; a delivery device for delivering the solvent to the solvent reservoir; a carrier substrate holder for holding the carrier substrate, said carrier substrate holder engages with the carrier substrate (i) to apply a force to the carrier substrate in a generally downward direction and (ii) to apply a force to the carrier substrate in a generally upward direction; a film frame holder that engages with the film frame to apply to the film frame (i) at least one force in a generally upward direction and (ii) at least one force in a generally downward direction; and a control unit for: wherein the at least one force applied to the film frame in the generally upward direction by the film frame holder is directed against the downward force applied to the carrier substrate by the carrier substrate holder to deform at least the stripping section of the flexible film, and the at least one force applied to the film frame in the generally downward direction by the film frame holder is directed against the upward force applied to the carrier substrate by the carrier substrate holder to deform at least the stripping section of the flexible film.
