    摘要: Improved compositions and processes for zincating magnesium and magnesium alloy substrates. An aqueous zincating composition having a pH of from about 8 to about 11 and including zinc ions, a complexing agent, fluoride ions and a reducing agent. A non-electrolytic process for zincating a magnesium or magnesium alloy substrate, including immersing the substrate in the non- electrolytic aqueous zincating composition for a time sufficient to deposit a zincate on the substrate. A non-electrolytic process for zincating a magnesium or magnesium alloy substrate, including preparing a aqueous non-electrolytic composition comprising zinc ions, a complexing agent, fluoride ions and a pH in the range from about 8 to about 11; adding to the composition an amount of a reducing agent sufficient to improve deposition of zincate on the magnesium or magnesium alloy substrate; and immersing the substrate in a composition for a time sufficient to deposit the zincate on the substrate.

    摘要: The invention relates to a method for producing an anti-corrosive cover layer, a surface to be treated being brought into contact with an aqueous treatment solution containing chromium(III) ions and at least one phosphate compound and an organosol. The method improves the anti-corrosion protection of metal, in particular zinc-containing, surfaces and zinc-containing surfaces provided with conversion layers. This produces or improves the decorative and functional properties of the surfaces. In addition, it avoids the known problems arising with the use of chromium(VI)-containing compounds or multi-stage processes in which a chromium ion-containing passivation layer and a seal are applied consecutively.

    摘要: The invention relates to a method for electroless (immersion) plating of tin and tin alloys having a thickness of ≥ 1 µm as a final finish in the manufacture of printed circuit boards, IC substrates, semiconductor wafers and the like. The method utilizes an electroless plated sacrificial layer of copper between the copper contact pad and the electroless plated tin layer which is dissolved completely during tin plating. The method compensates the undesired loss of copper from a contact pad during electroless plating of thick tin layers.

    摘要: The present invention concerns a method for electrodepositing copper into a trench pattern in a structure including the following steps: forming a patterned metal hard mask layer over the dielectric substrate layer; patterning the dielectric layer by using an etch through the patterned metal-based hardmask optionally, forming a barrier and / or liner layer over the surface of the patterned dielectric substrate layer and the hard mask layer; forming over the barrier layer and the hard mask layer a basic metal seed layer by a wet chemical plating method to provide sufficient conductance for subsequent electrolytic deposition of copper; and immersing the dielectric substrate into an electrolytic copper plating bath in an electrolytic copper plating system to electrodeposit copper into the patterned dielectric substrate layer. The hard mask only needs to be removed after copper deposition.
