    摘要: Abstract of the Disclosure A deposition / etching /deposition process is provided for filling a gap in a surface of a substrate. A liner is formed over the substrate so that distinctive reaction products are formed when it is exposed to a chemical etchant. The detection of such reaction products thus indicates that the portion of the film deposited during the first etching has been removed to an extent that further exposure to the etchant may remove the liner and expose underlying structures. Accordingly, the etching is stopped upon detection of distinctive reaction products and the next deposition in the deposition /etching /deposition process is begun.

    摘要: A method of depositing a film on a substrate disposed in a substrate processing chamber. The method includes depositing a first portion of the film by forming a high density plasma from a first gaseous mixture flown into the process chamber. The deposition processes is then stopped and part of the deposited first portion of the film is etched by flowing a halogen etchant into the processing chamber. Next, the surface of the etched film is passivated by flowing a passivation gas into the processing chamber, and then a second portion of the film is deposited over the first portion by forming a high density plasma from a second gaseous mixture flown into the process chamber. In one embodiment the passivation gas consists of an oxygen source with our without an inert gas.
