Abstract: A system of forming a debonding layer includes a debonding layer forming device configured to form a coating layer by coating a graphene oxide layer on a support substrate. The debonding layer forming device is configured to form a debonding layer by heat-treating the coating layer. An optical measuring device is configured to classify the support substrate into a plurality of cell areas. The optical measuring device is configured to measure a thickness of at least one of the coating layer in at least one cell area of the plurality of cell areas.

Abstract: A cutting apparatus includes: a stage on which is disposed a preliminary stacked body from which a cut stacked body having an edge is formed; a cutting unit movable along a first direction corresponding to an extension direction of the edge of the cut stacked body and with which the preliminary stacked body is cut to form the cut stacked body; a first detaching unit movable in a direction forming an acute angle with the first direction and including a first detaching tool which contacts the cut stacked body in detaching of the cut stacked body from the carrier substrate; and a second detaching unit movable in a direction parallel to the first direction and including a second detaching tool which is inserted between the cut stacked body and the carrier substrate in the detaching of the cut stacked body from the carrier substrate.
