Abstract:
1. A method of forming a silicon oxide layer on a patterned substrate having a trench in a plasma-free substrate processing region in a substrate processing chamber, the method comprising: flowing a hydrogen-containing precursor into a first plasma region to produce a radical precursor while flowing an oxygen-containing precursor into a second plasma region to produce a radical-oxygen precursor; concurrently combining the radical precursor and the radical-oxygen precursor with a carbon-free silicon-containing precursor in the plasma-free substrate processing region, wherein the carbon-free silicon-containing precursor contains nitrogen; depositing a flowable silicon-oxygen-and-nitrogen-containing layer on the substrate, wherein the flowable silicon-oxygen-and-nitrogen-containing layer flows into the trench on a deposition surface of the patterned substrate as the flowable silicon-oxygen-and-nitrogen-containing layer deposits; and annealing the silicon-oxygen-and-nitrogen-containing layer at an annealing temperature in an oxygen-containing atmosphere to increase the oxygen-content and decrease the nitrogen-content to form a silicon oxide layer.
