Patent ID: 7048968

Claim:
A method of depositing material over a substrate, comprising: providing a first precursor and a second precursor different from the first precursor; providing an atomic layer deposition reaction chamber having a substrate therein, the substrate having a surface; performing at least one iteration of the following sequence: flowing the first precursor into the chamber to form a first component monolayer deposited over a surface of the substrate; after forming the first component monolayer, purging substantially all of any of the first precursor remaining free in the chamber from the chamber; after purging substantially all of the first precursor from the reaction chamber, flowing the second precursor into the chamber to form a second component over the surface of the substrate; after forming the second component, purging substantially all of any of the second precursor remaining free in the chamber from the chamber; wherein at least one of the first and second precursors is dispersed in a supercritical fluid as it is flowed into the reaction chamber; wherein the first precursor comprises a metal; wherein the first component monolayer comprises the metal; wherein the second precursor comprises oxygen; and wherein the second component comprises the oxygen.
