发明名称 PRECURSOR ADDITION TO SILICON OXIDE CVD FOR IMPROVED LOW TEMPERATURE GAPFILL
摘要 Methods of depositing silicon oxide layers on substrates involve flowing a silicon-containing precursor, an oxidizing gas, water and an additive precursor into a processing chamber such that a uniform silicon oxide growth rate is achieved across the substrate surface. The surface of silicon oxide layers grown according to embodiments may have a reduced roughness when grown with the additive precursor. In other aspects of the disclosure, silicon oxide layers are deposited on a patterned substrate with trenches on the surface by flowing a silicon-containing precursor, an oxidizing gas, water and an additive precursor into a processing chamber such that the trenches are filled with a reduced quantity and/or size of voids within the silicon oxide filler material.
