TUNNEL-TYPE METAL MASK AND PRODUCTION METHOD

摘要

The present invention relates to a tunnel type metal mask by a plating method. The tunnel type metal mask comprises a main line and a bridge line supporting the main line and sequentially grows the main line by a plating process after growing the bridge line by the plating process. The mask of the present invention attaches a fine bridge line to the upper part of the main line in order to support the main line forming the mask. The present invention is able to produce the main line consisting of conductive metal and is able to plate the bridge line in the upper part of the main line. The bridge line crosses the main line and is integrally combined with the main line in the upper part of the main line. The present invention is able to locate ink, pigment, liquid phase resin and the like on a substrate as the height of the main line. The bridge line firmly supports the main line. The bridge line is desirable that a thickness is thin and is formed with a thin line.
