摘要： This invention is directed to a method of forming electrical conductors comprised of conductive metals generally carried on a substrate. In the method, a conductor formulation generally comprised of metal particles or metal precursor or mixture thereof, typically in the form of an ink or paste, is applied to the substrate and converted into a conductive metal by application of sufficient heat and for a sufficient time to effect sintering thereof while in the presence of a negatively charged ionic reducing gas.

摘要： In the present invention, a metal halide film is grown which is then reduced to the metal film rather than growing the metal film directly on the substrate surface. In certain embodiments, a metal halide film is grown from at least two precursors: a halogen-containing precursor and a metal-containing precursor. The metal halide film is then exposed to a reducing agent to form the metal film. In certain preferred embodiments, the metal halide film is exposed to the reducing agent prior to the completion of the growing step.

摘要： We have used the state-of-the-art computational chemistry techniques to identify adhesion promoting layer materials that provide good adhesion of copper seed layer to the adhesion promoting layer and the adhesion promoting layer to the barrier layer. We have identified factors responsible for providing good adhesion of copper layer on various metallic surfaces and circumstances under which agglomeration of copper film occur. Several promising adhesion promoting layer materials based on chromium alloys have been predicted to be able to significantly enhance the adhesion of copper films. Chromium containing complexes of a polydentate β-ketoiminate have been identified as chromium containing precursors to make the alloys with chromium.
