Patent ID: 8366873

Claim:
A debonder apparatus for debonding a temporary bonded wafer pair, comprising: a chuck assembly comprising a chuck and a first wafer holder configured to hold a first wafer of said temporary bonded wafer pair in contact with a top surface of the chuck; a flex plate assembly comprising a flex plate and a second wafer holder configured to hold a second wafer of said temporary bonded wafer pair in contact with a first surface of the flex plate, wherein said flex plate is configured to be placed above the top surface of the chuck; a contact roller arranged adjacent to a first edge of the chuck and comprising means for pushing and lifting up a first edge of the flex plate; a resistance roller comprising means for traversing horizontally over said flex plate and means for applying a downward force upon the flex plate; and wherein said contact roller pushes and lifts up the first edge of the flex plate while the resistance roller simultaneously applies said downward force upon said flex plate and traverses horizontally away from the first edge of the flex plate and thereby said temporary bonded wafer pair delaminates along a release layer and said first and second wafers are separated from each other.
