    摘要： A debonder apparatus for debonding two via an adhesive layer combined with a release layer temporary bonded wafers includes a chuck assembly, a flex plate assembly and a contact roller. The chuck assembly includes a chuck and a first wafer holder configured to hold wafers in contact with the top surface of the chuck. The flex plate assembly includes a flex plate and a second wafer holder configured to hold wafers in contact with a first surface of the flex plate. The flex plate comprises a first edge connected to a hinge and a second edge diametrically opposite to the first edge, and the flex plate's first edge is arranged adjacent to a first edge of the chuck and the flex plate is configured to swing around the hinge and to be placed above the top surface of the chuck. The contact roller is arranged adjacent to a second edge of the chuck, which is diametrically opposite to its first edge. A debond drive motor is configured to move the contact roller vertical to the plane of the chuck top surface. In operation, a wafer pair, comprising a carrier wafer stacked upon and being bonded to a device wafer via an adhesive layer and a release layer, is placed upon the chuck so that the ubonded surface of the device wafer is in contact with the chuck top surface. Next, the flex plate swings around the hinge and is placed above the bottom chuck so that its first surface is in contact with the unbonded surface of the carrier wafer. Next, the contact roller is driven upward until it contacts and pushes the second edge of the flex plate up while the carrier wafer is held by the flex plate and the device wafer is held by the chuck via the second and first wafer holders, respectively. The contact roller push flexes the second edge of the flex plate and causes delamination of the wafer pair along the release layer.
