Abstract: Disclosed herein are methods for electrolessly coating copper onto a chromium metal powder, the method comprising adding a nickel-coated chromium powder to an aqueous electroless copper plating bath comprising a source of copper cations, a copper-cation complexing agent, a copper-cation reducing agent, and a first base, thereby forming a copper-coated chromium metal powder. Also disclosed are copper-coated chromium metal powders prepared by a disclosed method.

Abstract: An aqueous seeding solution of palladium acetate, acetic acid and chloride.

Abstract: A method to electrolessly plate a CoWP alloy on copper in a reproducible manner that is effective for a manufacturable process. In the method, a seed layer of palladium (Pd) is deposited on the copper by an aqueous seeding solution of palladium acetate, acetic acid and chloride. Thereafter, a complexing solution is applied to remove any Pd ions which are adsorbed on surfaces other than the copper. Finally, a plating solution of cobalt (Co), tungsten (W) and phosphorous (P) is applied to the copper so as to deposit a layer of CoWP on the Pd seed and copper.

Abstract: An integrated circuit structure is disclosed that has a layer of logical and functional devices and an interconnection layer above the layer of logical and functional devices. The interconnection layer has a substrate, conductive features within the substrate and caps positioned only above the conductive features.

Abstract: A structure incorporates very low dielectric constant (k) insulators with copper wiring to achieve high performance interconnects. The wiring is supported by a relatively durable low k dielectric such as SiLk or SiO2 and a very low k and less-robust gap fill dielectric is disposed in the remainder of the structure, so that the structure combines a durable layer for strength with a very low k dielectric for interconnect electrical performance.
