Abstract:
A method of growing elemental Cu, Ag, Au, Pd, Pt, Rh, Ir, Ru and/or Os thin films on a substrate by a chemical vapor deposition type process comprising:vaporizing a metal source material and a reducing agent capable of reducing the metal source material to elemental metal; feeding the metal source material and the reducing agent into a reaction space; and contacting the metal source material and the reducing agent with the substrate, wherein the reducing agent is a boron compound having the general formula (II) (R1)3-pBXpâ€ƒâ€ƒ(II) â€ƒwherein R1 is selected from the group consisting of a linear C1-C6 group, a branched C1-C6 group, and an aryl group, each R1 being selected independently of the other(s), X is a halogen, and p=0, 1 or 2.
