ABSTRACT:
A method for horizontally electroplating or electro deposition a thin film on a substrate comprises 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 an edge 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.
