  • Patent number: 8997821
    Abstract: A delamination system delaminates a laminated substrate, in which a first substrate and a second substrate are bonded together, into the first substrate and the second substrate. The delamination system has a first processing block processing the laminated substrate or the delaminated first substrate and a second processing block processing the delaminated second substrate. The first processing block has a delamination station having a delamination device that delaminates the laminated substrate transferred by a first transfer device into the first substrate and the second substrate. The second processing block has a second cleaning station and a delivery station. The second cleaning station has a second cleaning device cleaning the delaminated second substrate. The delivery station is disposed between the second cleaning station and the delamination station. The delivery station receives the delaminated second substrate from the delamination station and delivers it to the second cleaning station.

  • Patent number: 8986496
    Abstract: Device for stripping a product substrate from a carrier substrate connected to the product substrate by an interconnect layer by means of a flexible film that is mounted on a film frame and that comprises an adhesive layer for holding the product substrate in a bonding surface section of the film, the film being mounted on the film frame in an attachment section of the film that surrounds the bonding surface section, and the film comprising a stripping section that is located between the bonding surface section and the attachment section, the device having stripping means for effecting a stripping of the product substrate from the carrier substrate from a periphery of the product substrate.

  • Patent number: 8919412
    Abstract: A debonder apparatus for debonding two via an adhesive layer temporary bonded wafers includes a top chuck assembly, a bottom chuck assembly, a static gantry supporting the top chuck assembly, an X-axis carriage drive supporting the bottom chuck assembly, and an X-axis drive control. The top chuck assembly includes a heater and a wafer holder. The X-axis drive control drives horizontally the bottom chuck assembly from a loading zone to a process zone under the top chuck assembly and from the process zone back to the loading zone. A wafer pair comprising a carrier wafer bonded to a device wafer via an adhesive layer is placed upon the bottom chuck assembly at the loading zone oriented so that the unbonded surface of the device wafer is in contact with the bottom assembly and is carried by the X-axis carriage drive to the process zone under the top chuck assembly and the unbonded surface of the carrier wafer is placed in contact with the top chuck assembly.
