Claim Text:
1. Method for stripping a product substrate off a carrier substrate connected to the product substrate by a bonding layer therebetween, wherein said carrier substrate connected to the product substrate by a bonding layer forms a carrier-product substrate combination, said method comprising: connecting a flexible film to a film frame to form a solvent reservoir that receives a solvent for dissolving the bonding layer; mounting the carrier-product substrate combination to the flexible film by fixing the product substrate to a contacting surface section of the flexible film using an adhesive; receiving at least the product substrate and the bonding layer of the carrier-product substrate combination into the solvent reservoir; delivering the solvent into the solvent reservoir; and at least partially dissolving the bonding layer between the carrier substrate and the product substrate by exposing the bonding layer of the carrier-product substrate combination to the solvent received by the solvent reservoir, wherein said bonding layer connecting the product substrate to the carrier substrate is comprised of a plurality of different adhesive layers.
