    摘要: A method of depositing a high density plasma silicon oxide layer having improved gapfill capabilities. In one embodiment the method includes flowing a process gas consisting of a silicon-containing source, an oxygen-containing source and helium into a substrate processing chamber and forming a plasma from the process gas. The ratio of the flow rate of the helium with respect to the combined flow rate of the silicon source and oxygen source is between 0.5:1 and 3.0:1 inclusive. In one particular embodiment, the process gas consists of monosilane (SiH4), molecular oxygen (O2) and helium.
