Claim 8:
9. A cutting apparatus comprising:
a stage configured to receive a carrier substrate and a stacked body which is on the carrier substrate, the stage including a corner and an edge which extends from the corner along a first direction;
a cutter which is adjacent to the stage and cuts the stacked body both vertically and along the first direction into a cut stacked body;
the stage including:
a central portion configured to receive the stacked body and having a flat surface,
an inclined portion extended from the central portion and configured to receive a cut portion of the stacked body which is adjacent to the cut stacked body, and
a plurality of vacuum holes defined in the stage, the plurality of vacuum holes configured to maintain the carrier substrate and the stacked body on the stage;

a first detaching tool which is adjacent to the stage, is movable in a direction forming an acute angle with the first direction, and includes an adhesive roller, the first detaching tool configured to perform a first initial detaching of the cut stacked body with respect to the carrier substrate from the corner; and
a second detaching tool which is adjacent to the stage, is movable along the first direction, and includes a knife protruding in a second direction intersecting the first direction, the second detaching tool configured to perform a second initial detaching of the cut stacked body with respect to the carrier substrate from the edge,
wherein
among the plurality of vacuum holes of the stage, a suction force generated by vacuum holes at the inclined portion is greater than a suction force generated by vacuum holes at the central portion and
the first initial detaching includes the adhesive roller of the first detaching tool moved in the acute angle with the first direction together with being contactable with an upper surface of the cut stacked body which is at the corner, together with the second initial detaching including the knife of the second detaching tool moved in the first direction together with being insertable between the carrier substrate and the cut stacked body.
