Abstract:
1. A method for horizontally electroplating or electro deposition a thin film on a substrate, comprising the steps of: transferring and positioning a substrate on a substrate supporter; the substrate being positioned approximately horizontally; moving a plurality of stop plates to enclose horizontal edges of the substrate so as to form with an enclosure around the edges of the substrate; moving a first electrode to be in contact with a portion of the substrate; the portion being a non-wired area; moving a second electrode to be above and not in contact with the substrate; wherein the second electrode has a polarity opposite to that of the first electrode; and filling electroplating liquid into the enclosure formed by the stop plates so as to be in contact with the second electrode above the substrate for electroplating or electro deposition; wherein the stop plates enclose a peripheral of the substrate; and the supporter, the substrate, the stop plates, the first electrode, the second electrode and the electroplating liquid are movable synchronously.
