摘要： A process is provided for depositing an silicon oxide film on a substrate disposed in a process chamber. A process gas that includes a halogen source, a fluent gas, a silicon source, and an oxidizing gas reactant is flowed into the process chamber. A plasma having an ion density of at least 1011 ions/cm3 is formed from the process gas. The silicon oxide film is deposited over the substrate with a halogen concentration less than 1.0%. The silicon oxide film is deposited with the plasma using a process that has simultaneous deposition and sputtering components. The flow rate of the halogen source to the process chamber to the flow rate of the silicon source to the process chamber is substantially between 0.5 and 3.0.

摘要： A processing chamber is seasoned by providing a flow of season precursors to the processing chamber. A high-density plasma is formed from the season precursors by applying at least 7500 W of source power distributed with greater than 70% of the source power at a top of the processing chamber. A season layer having a thickness of at least 5000 Å is deposited at one point using the high-density plasma. Each of multiple substrates is transferred sequentially into the processing chamber to perform a process that includes etching. The processing chamber is cleaned between sequential transfers of the substrates.

摘要： Methods are disclosed of depositing a silicon oxide film on a substrate disposed in a substrate processing chamber. The substrate has a gap formed between adjacent raised surfaces. A first portion of the silicon oxide film is deposited over the substrate and within the gap using a high-density plasma process. Thereafter, a portion of the deposited first portion of the silicon oxide film is etched back. This includes flowing a halogen precursor through a first conduit from a halogen-precursor source to the substrate processing chamber, forming a high-density plasma from the halogen precursor, and terminating flowing the halogen precursor after the portion has been etched back. Thereafter, a halogen scavenger is flowed to the substrate processing chamber to react with residual halogen in the substrate processing chamber. Thereafter, a second portion of the silicon oxide film is deposited over the first portion of the silicon oxide film and within the gap using a high-density plasma process.

摘要： Methods are disclosed for depositing a silicon oxide film on a substrate disposed in a substrate processing chamber. The substrate has a gap formed between adjacent raised surfaces. A silicon-containing gas, an oxygen-containing gas, and a fluent gas are flowed into the substrate processing chamber. A high-density plasma is formed from the silicon-containing gas, the oxygen-containing gas, and the fluent gas. A first portion of the silicon oxide film is deposited using the high-density plasma at a deposition rate between 900 and 6000 Å/min and with a deposition/sputter ratio greater than 30. The deposition/sputter ratio is defined as a ratio of a net deposition rate and a blanket sputtering rate to the blanket sputtering rate. Thereafter, a portion of the deposited first portion of the silicon oxide film is etched. A second portion of the silicon oxide film is deposited over the etched portion of the silicon oxide film.

摘要： A method of forming a dielectric material in a substrate gap using a high-density plasma is described. The method may include depositing a first portion of the dielectric material into the gap with the high-density plasma. The deposition may form a protruding structure that at least partially blocks the deposition of the dielectric material into the gap. The first portion of dielectric material is exposed to an etchant that includes reactive species from a mixture that includes NH3 and NF3. The etchant forms a solid reaction product with the protruding structure, and the solid reaction product may be removed from the substrate. A final portion of the dielectric material may be deposited in the gap with the high-density plasma.
