Filling of narrow and / or high aspect ratio gaps and trenches with silicate glass is accomplished at reduced temperatures and without reflow by etching the glass concurrently with thermal chemical vapor deposition of the glass such that the deposition rate will exceed the etching rate by a relatively small net deposition rate near the surface with the excess deposition rate increasing over the depth of the trench or gap. The as-deposited glass film is made dense and stable by carrying out the concurrent etch and deposition process at an elevated temperature but which is within the maximum temperature and heat budget which can be tolerated by structures formed by previously performed processes.
