Abstract:
1. An apparatus for fabricating a flat panel display device, comprising: an imprinting mold connected to a substrate to form a thin film pattern on the substrate; first adsorption pads configured to vacuum-adsorb the first region of the imprinting mold, for separating the imprinting mold from the substrate; second adsorption pads configured to vacuum-adsorb the second region including a periphery of the imprinting mold, for separating the imprinting mold from the substrate; first vacuum pins each connected to each of the first adsorption pads through a first connector; and second vacuum pins each connected to each of the second adsorption pads through a second connector, wherein the first and second vacuum pins are vertically moved to separate the imprinting mold vacuum-adsorbed on the first and second adsorption pads from the substrate, wherein the first connector is formed on the center of an upper surface of the first adsorption pads, wherein the second connector is formed on the periphery of the upper surface of the second adsorption pad off-center toward an outer edge of the imprinting mold away from the first connector, such that an application point of a force to vertically elevate the second adsorption pad is arranged off-center in the periphery of the second adsorption pad, and wherein a thickness of the second adsorption pad at an area of the second connector and the second vacuum pins is larger than the thickness of the rest of the second adsorption pad, such that a thickest portion of the second adsorption pad is off-center of the second adsorption pad and is adjacent to the outer edge of the imprinting mold.
