Abstract:
1. Device for releasing an interconnect layer that provides a connection between a carrier and a wafer to form a carrier-wafer combination, wherein said interconnect layer provides the connection at a peripheral edge of the carrier-wafer combination said device comprising: a connection release means for providing an immersion bath that receives the carrier-wafer combination to unfix the connection, said connection release means including: a rotation means for rotating the carrier-wafer combination to move only the peripheral edge of the carrier-wafer combination through the working chamber of the connection release means to contact only the peripheral edge of the carrier-wafer combination with the solvent filling the working chamber, thereby releasing the interconnect layer from at least one of the carrier and the wafer and breaking the connection at the peripheral edge of the carrier-wafer combination.
