Abstract:
1. A method, comprising: transporting a metal containing precursor within a transport medium through a chamber containing a transport space to a substrate, wherein the temperature in a the transport space is lower than a decomposition temperature of the metal containing precursor; depositing a metal layer onto the substrate through the decomposition at the substrate of the metal-containing precursor, wherein the temperature at the substrate is greater than the decomposition temperature of the metal containing precursor; wherein the temperature of the metal containing precursor in the transport space is directly measured and the temperature of the metal containing precursor in the transport space is controlled using the direct measurement; and the rate of deposition and the quality of said metal layer on said substrate are controlled by control of said substrate temperature, the temperature of the metal containing precursor in the transport space and by maintaining a gas/liquid equilibrium in said transport medium with precursor coexisting in liquid and gas phases thereby maintaining saturation conditions of said precursor in the gas phase of said transport medium.
