Abstract:
1. An atomic layer deposition method for depositing a ruthenium-containing film onto one or more substrates, the method comprising the steps of: a) introducing vapors of an organometallic precursor into a reactor containing at least one substrate, the organometallic precursor comprising a metal selected from the group consisting of strontium, calcium, barium, and combinations thereof; b) depositing at least a part of the organometallic precursor onto the at least one substrate to form a layer using an atomic layer deposition process; c) introducing vapors of ruthenium tetroxide (RuO d) reacting the vapors of ruthenium tetroxide with the layer deposited in step (b) to form the ruthenium-containing film using an atomic layer deposition process, wherein the ruthenium-containing film is a ruthenate film and is formed without the introduction of a separate oxygen-containing reactant.
