    • PURPOSE: A method and apparatus for separating out metal copper according to an electroplating of copper is provided. CONSTITUTION: A substrate is brought into contact with the processing solution by directly dipping the substrate into the processing solution in a tank, spraying the processing solution over the substrate while the substrate is being rotated in a horizontal plane at a high speed as with a spin dryer, or supplying the processing solution by a pump into a dedicated dipping chamber in which the substrate is set at a predetermined position. When the substrate is thus brought into the processing solution, a thin film of the organic substance and/or the sulfur compound is coated on the processed surface of the substrate. An extra processing solution is preferably removed from the substrate, and then the substrate is plated with copper according to a conventional process. In this manner, metal copper is prevented from being separated out locally on the processed surface of the substrate, and the substrate is plated to provide a mirror-like glossy surface. Further, the size of humps in an area of closely spaced interconnections on the processed surface of the substrate can be suppressed.
    • 目的:提供一种根据铜电镀分离金属铜的方法和装置。 构成:通过将基板直接浸入槽中的处理溶液中,使基板与处理溶液接触,将基板在水平面内以高速旋转在基板上喷涂处理溶液,如同旋转 干燥器,或者通过泵将处理溶液供给到其中将基板设置在预定位置的专用浸渍室中。 因此,在将基板加入到处理液中时,有机物和/或硫化合物的薄膜被涂布在基板的被处理面上。 优选从衬底去除额外的处理溶液,然后根据常规方法将衬底镀铜。 以这种方式,防止金属铜在基板的被处理表面上局部分离,并且将基板电镀以提供镜面状的光泽表面。 此外,可以抑制在基板的经处理的表面上的紧密间隔的互连区域中的凸起的尺寸。
