Abstract: A substrate debonding apparatus includes a chuck attached to a second surface opposite to the first surface of the semiconductor substrate via a second adhesive layer. The chuck is configured to support a lower portion of a base film having a cross-sectional area in a horizontal direction greater than a cross-sectional area of the semiconductor substrate in the horizontal direction. The semiconductor debonding apparatus further includes a fixing ring arranged above the chuck and configured to fix in position an edge portion of the base film, and a cover ring arranged above the fixing ring and configured to adjust a diameter of an opening exposing the carrier substrate. The cover ring includes a guide frame arranged above the fixing ring, and a plurality of cover blades configured to move in a horizontal direction determined by the guide frame.
