A process for forming silicate glass layers on substrates is disclosed. A silicate glass layer is first deposited onto a substrate, such as a semiconductor wafer. The wafer is then placed in a thermal processing chamber and heated in the presence of a reactive gas. The object is heated to a temperature sufficient for reflow of the silicate glass. In one embodiment, the atmosphere contained within the processing chamber comprises steam in combination with a reactive gas. The reactive gas can be, for instance, hydrogen, oxygen, nitrogen, dinitrogen oxide, ozone, hydrogen peroxide, atomic and/or molecular hydrogen, or radicals or mixtures thereof.
