    • PURPOSE:To obtain a substrate having through holes and showing high reliability and resolving power by laminating a liq. photosensitive resin on both sides of a substrate having electrically conductive metallic layers, curing the resin by exposure, forming polymer images by washing-out, removing the unmasked parts of the metallic layers, and removing the images. CONSTITUTION:Transparent flexible carriers 3 are coated with a liq. photosensitive resin 2 in a uniform thickness, and the resin coated surfaces are placed as opposed to a substrate 1 having electrically conductive metallic layers 1b. The carriers 3 are pressed against the substrate 1 under uniform pressure to laminate the resin 2 in a uniform thickness. Mask films 11 are brought into contact with the surfaces of the carriers 3, and the resin 2 is exposed to active light to form polymer images. The carriers 3 are stripped from the substrate 1, the unpolymerized resin 2 is washed out, and the unmasked parts of the layers 1b are removed by etching using the polymer images 2a present on both sides of the substrate 1 at holes 1a for through holes and the necessary parts. The images 12a are then removed. Thus, a substrate having through holes is obtd.
    • 目的:获得具有通孔的基板,通过层压液晶显示高可靠性和分辨能力。 在具有导电金属层的基板的两侧上具有感光性树脂,通过曝光固化树脂,通过洗去形成聚合物图像,去除金属层的未被遮蔽的部分,以及去除图像。 构成:透明柔性载体3涂有液体。 感光性树脂2的厚度均匀,与具有导电性金属层1b的基板1相对地设置树脂被覆面。 载体3在均匀的压力下压靠基板1,以均匀的厚度层压树脂2。 掩模膜11与载体3的表面接触,并且树脂2暴露于活性光以形成聚合物图像。 载体3从基板1剥离,未聚合的树脂2被清洗,并且通过使用存在于基板1的两侧的聚合物图像2a的孔1a中的通孔进行蚀刻来除去层1b的未掩蔽部分, 必要的部分。 然后移除图像12a。 因此,具有通孔的基板。
