Patent ID: 7771533

Claim:
An atomic layer deposition (ALD) process for producing a thin film comprising silicon dioxide on a substrate by alternating, saturating surface reactions, the process comprising: contacting a substrate in a flow type reactor with a vaporized silicon compound selected from the group consisting of amino substituted silanes and silazanes, wherein a substrate temperature is selected such that the silicon compound chemisorbs to the substrate to form a single molecular layer and does not condense or decompose on the substrate, said silicon compound comprising at least one organic ligand; removing unreacted silicon compound; and converting the chemisorbed silicon compound into silicon dioxide by contacting it with a reactive vaporized oxygen source compound, wherein the reaction temperature is selected such that the silicon compound does not condense or decompose on the substrate surface; wherein the vaporized silicon compound and the reactive vaporized oxygen source compound are the only reactants used to form the silicon dioxide; and wherein when each reactant is contacting the substrate, the reactant flows continuously from an inlet of the reactor to an outlet of the reactor.
