    摘要: An object of the present invention is to improve the reliability and the yield of production of semiconductor integrated circuit devices by filling copper in the inside of features having a high aspect ratio for forming multi-layer interconnections composed of a plurality of interconnection layers which are connected to one another and to a copper electroplating bath suitable therefor. In the present invention, when the features are filled with copper, the use of a copper electroplating bath with an addition of cyanine dyes, for example, indolium compounds allows the copper plating to proceed preferentially from the bottoms of the features.

    摘要: Provided is a wiring board and production method thereof, wherein production of wiring by a full additive method is achieved. This is extremely useful in forming fine copper wiring featuring a high adhesion on an insulating resin substrate. A resin having an excellent alkali resistance is used as the insulating resin substrate, and the copper wiring is formed on the insulating resin substrate through a degenerated layer containing amide group and a metallic oxide layer of a metal having a reduction potential more base than that of copper. The degenerated layer can be provided by, e.g., introduction of amide group into the surface of the insulating resin substrate. The copper can be formed by processes including electroless plating. The insulating resin substrate has superb heat resistance and dimensional stability, and the formed structure can provide a highly packed wiring board.

    摘要: A multilayer wiring substrate which is high in connection reliability is provided through process steps of forming more than one opening, such as a via-hole in a dielectric layer laminated on a substrate, and then applying uniform copper plating to a surface portion of the dielectric layer including the opening to thereby form a wiring layer. An electroless copper plating solution with at least one of mandelonitrile and triethyltetramine mixed therein is used to perform the intended electroless copper plating. An alternative process makes use of a electroless copper plating solution with chosen additive agents or “admixtures” containing at least one of mandelonitrile and triethyltetramine plus eriochrome black T along with at least one of 2,2′-bipyridyl, 1,10-phenanthroline, and 2,9-dimethyl-1,10-phenanthroline.
