Abstract:
1. A method for depositing a dielectric layer over a substrate disposed in a substrate processing chamber, the substrate having a gap formed between adjacent raised surfaces, the method comprising: flowing a deposition gas into the process chamber; flowing an inert gas into the process chamber; forming a high-density plasma from the deposition gas and the inert gas to deposit a first portion of the dielectric layer over the substrate and within the gap using a process that has simultaneous deposition and sputtering components to provide a deposition-to etch ratio of the process defined by a set of process parameters; thereafter, changing the set of process parameters to decrease the deposition-to-etch ratio of the process; and thereafter changing the set of process parameters to increase the deposition-to-etch ratio of the process and deposit a second portion of the dielectric layer over the substrate.
