Claim 0:
1. 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 first detaching tool which is adjacent to the stage and includes an adhesive roller;
a second detaching tool which is adjacent to the stage and includes a knife protruding in a second direction intersecting the first direction;
a first guide rail which is positioned adjacent to the stage and lengthwise extending along the first direction;
a first horizontal connector which is movably connected to the first guide rail along the first direction;
a second guide rail which is positioned adjacent to the stage, the first detaching tool being movably connected to the second guide rail along the second guide rail;
a lengthwise extending direction of the first guide rail and a lengthwise extending direction of the second guide rail forming an acute angle with each other,
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 cutter being movably connected to the first horizontal connector along the second direction; and
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 when the second detaching tool performs a second initial detaching of the cut stacked body with respect to the carrier substrate from the edge,
wherein
the first initial detaching includes the adhesive roller of the first detaching tool moved in the lengthwise extending direction of the second guide rail at a same time the adhesive roller contacts with an upper surface of the cut stacked body which is at the corner, and
the second initial detaching includes the knife of the second detaching tool moved in the first direction at a same time the knife is inserted between the carrier substrate and the cut stacked body.
