A method and a deposition system for increasing deposition rates of metal layers from metal-carbonyl precursors using CO gas and a dilution gas. The method includes providing a substrate in a process chamber of a processing system, forming a process gas containing a metal-carbonyl precursor vapor and a CO gas, diluting the process gas in the process chamber, and exposing the substrate to the diluted process gas to deposit a metal layer on the substrate by a thermal chemical vapor deposition process. The deposition system contains a substrate holder configured for supporting and heating a substrate in a process chamber having a vapor distribution system, a precursor delivery system configured for forming a process gas containing a metal-carbonyl precursor vapor and a CO gas and for introducing the process gas to the vapor distribution system, a dilution gas source configured for adding a dilution gas to the process gas in the process chamber, and a controller configured for controlling the deposition system during exposure of the substrate to the diluted process gas to deposit a metal layer on the substrate by a thermal chemical vapor deposition process.

A method for increasing deposition rates of metal layers from metal-carbonyl precursors by mixing a vapor of the metal-carbonyl precursor with CO gas. The method includes providing a substrate in a process chamber of a deposition system, forming a process gas containing a metal-carbonyl precursor vapor and a CO gas, and exposing the substrate to the process gas to deposit a metal layer on the substrate by a thermal chemical vapor deposition process.

A method is provided for forming a metal layer on a substrate using an intermittent precursor gas flow process. The method includes exposing the substrate to a reducing gas while exposing the substrate to pulses of a metal-carbonyl precursor gas. The process is carried out until a metal layer with desired thickness is formed on the substrate. The metal layer can be formed on a substrate, or alternately, the metal layer can be formed on a metal nucleation layer.

The present disclosure provides novel methods of making aluminum complexes with utility for promoting epoxide carbonylation reactions. Methods include reacting neutral metal carbonyl compounds with alkylaluminum complexes.

A process for synthesizing metal nanopowders by introducing metal carbonyl into an induction plasma torch. By taking advantage of the much lower dissolution temperature of carbonyl as opposed to the high melting temperature of conventional metal powder feeds less torch power is required. Moreover, in contrast to current powder production techniques utilizing electrode based plasma torches, the induction plasma torch does not introduce contaminants into the nanopowder.
