Patent ID: 8507038

Claim:
A method for producing a coated substrate, the method comprising: providing a copper precursor and a substrate, the copper precursor being a copper(I) complex that contains no fluorine; depositing a copper-containing layer using atomic layer deposition (ALD) at least on partial regions of a surface of the substrate by using the precursor, wherein the precursor is a complex of the formula L 2 Cu(X∩X) where L are identical or different σ-donor-π-acceptor ligands and/or identical or different σ,π-donor-π-acceptor ligands, and X∩X is a bidentate ligand selected from the group consisting of β-diketonates, β-ketoiminates, β-diiminates, amidinates, carboxylates and thiocarboxylates; and obtaining a copper-containing layer free of defects and having uniform thickness.
