Patent ID: 8894807

Claim:
Device for stripping, in combination with a product substrate and a carrier substrate, the carrier substrate connected to the product substrate by an interconnect layer, wherein the device for stripping separates the product substrate from the carrier substrate, the device comprising: a flexible film having an upper surface and a lower surface, the flexible film including: a bonding surface section on the lower surface, an adhesive layer on the bonding surface section, the adhesive layer for holding the product substrate on the bonding surface section of the flexible film, an attachment section on the lower surface of the film wherein the attachment section surrounds the outer periphery of the bonding surface section, and a stripping section of the flexible film located between the bonding surface section and the attachment section; a film frame mounted to the flexible film, the film frame mounted to the lower surface of the flexible film at the attachment section; a stripping means for stripping the product substrate from the carrier substrate from at least a periphery of the product substrate; and a connection release means comprising a fluid, wherein the connection release means is disposed only around an outer periphery of the product substrate.
