  • Patent number: 9376758
    Abstract: An electroplating method can securely and efficiently fill a plated metal into deep high-aspect ratio vias in a bottom-up manner without producing defects in the plated metal. The electroplating method includes: immersing a substrate, having vias formed in a surface, and an anode in a plating solution in a plating tank, the anode being disposed opposite the surface of the substrate; and intermittently passing a plating current at a constant current value between the substrate and the anode in such a manner that the supply and the stop of the plating current are repeated, and that the proportion of a current supply time during which the plating current is supplied increases with the progress of plating, thereby filling a plated metal into the vias.

  • Publication number: 20120255864
    Abstract: An electroplating method is capable of reliably embedding via holes with a plated metal such as copper or the like when a substrate with a seed layer of a metal having a greater ionization tendency than hydrogen is electroplated using an acidic plating solution such as a copper sulfate plating solution. The electroplating method including preparing a substrate having via holes covered with a first metal, which has a greater ionization tendency than hydrogen, in a surface thereof, pretreating the substrate by immersing the substrate in a pretreatment solution in which a second metal that is more noble than the first metal or a salt thereof is dissolved, and then electroplating the surface of the substrate to embed the second metal or a third metal in the via holes.
