Abstract:
A method for the chemical vapor deposition of a copper-based film onto a substrate, comprising:(a) introducing into a deposition chamber:(i) a substrate;(ii) a copper source precursor in a vapor state, wherein the copper source precursor comprises a mixture of at least one ligand-stabilized copper (I) .beta.-diketonate precursor; and at least one copper (II) .beta.-diketonate precursor; and(iii) at least one transport gas, different than said copper source precursor, wherein the at least one transport gas comprises a reactant gas; and(b) maintaining a reaction substrate temperature of from about 50.degree. C. to about 500.degree. C. for a period of time sufficient to deposit the copper-based film on said substrate.
