Abstract:
1. A method of forming a silicon oxide layer on a substrate, the method comprising: forming a silicon-nitrogen-and-hydrogen-containing layer by: flowing an unexcited precursor into a remote plasma region to produce a radical-precursor, combining a silicon-containing precursor with the radical-precursor in a plasma-free substrate processing region, and depositing the silicon-nitrogen-and-hydrogen-containing layer on the substrate; curing the silicon-nitrogen-and-hydrogen-containing layer in an ozone-containing atmosphere to convert the silicon-nitrogen-and-hydrogen-containing layer to a silicon-and-oxygen-containing layer; and exposing the silicon-and-oxygen-containing layer to a humid atmosphere having at least 50% relative humidity to convert the silicon-and-oxygen-containing layer to a silicon oxide layer, wherein the substrate temperature is greater than 25° C. and less than 100° C. during the exposing operation.
