摘要： A method of forming a silicon oxide layer over a substrate disposed in a high density plasma substrate processing chamber. The silicon oxide layer is formed by flowing a process gas including a silicon-containing source, an oxygen-containing source, an inert gas and a hydrogen-containing source into the substrate processing chamber and forming a high density plasma (i.e., a plasma having an ion density of at least 1null1011 ions/cm3) from the process gas to deposit said silicon oxide layer over said substrate. In one embodiment, the hydrogen-containing source in the process gas is selected from the group of H2, H2O, NH3, CH4 and C2H6.

摘要： A substrate support utilized in high-density plasma chemical vapor deposition (HDP-CVD) processing functions as a radio frequency (RF) electrode (e.g., a bias RF cathode). An upper surface of the substrate support has a central upper surface portion and a peripheral upper surface portion, with the peripheral upper surface portion recessed relative to the central upper surface portion. The upper surface of the support extends beyond an outer edge of the substrate when the substrate is positioned on the substrate support. This extension in the support upper surface may enhance process performance by reducing electric field edge effects, as well as by improving directional distribution of ions traveling to the substrate. Since the peripheral upper surface portion is recessed relative to the central upper surface portion, a detachable shield can be disposed on the peripheral upper surface portion for preventing undesirable deposition on, or chemical attack of, the peripheral upper surface portion, without interfering with positioning of the substrate.

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.
