Abstract:
1. A substrate carrying method for removing electrical charges on a substrate while the substrate is being transported by a substrate supporting unit, the method comprising: providing a substrate supporting unit having three rows of rollers that are parallel to each other; determining first and second paths, on opposite edges of a surface of the substrate respectively, through which two rows of the rollers of the substrate supporting unit travel during transportation of the substrate; determining a cutting line of the substrate in the middle of the substrate and parallel to each of the first and second paths; forming only three conductive strips with conductivity on the surface of the substrate to cover the first path, the second path, and the cutting line respectively; and transporting the substrate by the substrate supporting unit, wherein each row of the three rows of rollers of the grounded substrate supporting unit is in contact only with a respective one of the three conductive strips during transportation of the substrate; cutting the substrate into two pieces along the cutting line.
