摘要： A substrate processing system has a housing that defines a process chamber, a gas-delivery system, a high-density plasma generating system, a substrate holder, and a controller. The housing includes a sidewall and a dome positioned above the sidewall. The dome has physically separated and noncontiguous pieces. The gas-delivery system introduces e a gas into the process chamber through side nozzles positioned between two of the physically separated and noncontiguous pieces of the dome. The high-density plasma generating system is operatively coupled with the process chamber. The substrate holder is disposed within the process chamber and supports a substrate during substrate processing. The controller controls the gas-delivery system and the high-density plasma generating system.

摘要： A remote plasma process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after processing a substrate disposed in the substrate processing chamber. In one embodiment, the substrate is transferred out of the substrate processing chamber and a flow of a fluorine-containing etchant gas is introduced into a remote plasma source where reactive species are formed. A continuous flow of the reactive species from the remote plasmas source to the substrate processing chamber is generated while a cycle of high and low pressure clean steps is repeated. During the high pressure clean step, reactive species are flown into the substrate processing chamber while pressure within the substrate processing chamber is maintained between 4-15 Torr. During the low pressure clean step, reactive species are flown into the substrate processing chamber while reducing the pressure of the substrate processing chamber by at least 50 percent of a high pressure reached in the high pressure clean step.

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 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.

摘要： Apparatus and methods for distributing gas in a semiconductor process chamber are provided. In an embodiment, a gas distributor for use in a gas processing chamber comprises a body. The body includes a baffle with a gas deflection surface to divert the flow of a gas from a first direction to a second direction. The gas deflection surface comprises a concave surface. The concave surface comprises at least about 75% of the surface area of the gas deflection surface. The concave surface substantially deflects the gas toward a chamber wall and provides decreased metal atom contamination from the baffle so that season times can be reduced.
