Abstract:
An conducting carrier for removing electrostatic charges generated on a substrate, the substrate having a plurality of isolated first electrodes disposed along a first edge of the substrate, and a plurality of isolated second electrodes disposed along a second edge of the substrate, the conducting carrier comprising:a plate for supporting the substrate, the plate having a first side and a second side, when the substrate being supported by the plate, the first side of the plate being close to the first edge of the substrate, and the second side of the plate being close to the second edge of the substrate; a first conducting clipper positioned at the first side of the plate for simultaneously fixing the substrate onto the plate and conducting the plurality of first electrodes to a ground node; and a second conducting clipper positioned at the second side for simultaneously fixing the substrate onto the plate and conducting the plurality of second electrodes to the ground node, wherein when the substrate is fixed by the first and the second conducting clippers, the plurality of first and second electrodes are grounded so that the electrostatic charges produced during a sand blasting process are carried away from the first and second electrodes.
