Abstract:
1. Device for stripping a wafer from a carrier, wherein the carrier is fixed to the wafer by an interconnect layer that provides a connection between the carrier and the wafer, said device comprising: a receiving means for receiving a carrier-wafer combination comprised of the carrier and the wafer, said interconnect layer providing the connection between the carrier and the wafer at a peripheral edge of the carrier-wafer combination; a connection release means for unfixing the connection between the carrier and the wafer, said connection release means having at least one release device that includes: a rotation means for rotating the carrier-wafer combination to move the peripheral edge of the carrier-wafer combination through the working chamber of the connection release means to contact the peripheral edge of the carrier-wafer combination with the solvent, thereby dissolving the interconnect layer at the peripheral edge and breaking the connection between the carrier and the wafer; and stripping means for stripping the wafer from the carrier, or for stripping the carrier from the wafer.
