  • Publication number: 20150290921
    Abstract: A method of separating a device substrate from a carrier substrate on which said device substrate is disposed. A static electricity removal member is provided between the device substrate and the carrier substrate. The device substrate is separated from the carrier substrate. According to the above, since static electricity accumulating between the device substrate and the carrier substrate is removed by the static electricity removal member, the carrier substrate and the device substrate may be easily separated from each other. Thus, damage to the device due to static electricity when the carrier substrate and the device substrate are separated from each other may be prevented.
