    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 is portion, without interfering with positioning of the substrate.

    摘要: A substrate processing apparatus comprising a substrate processing chamber, a gas distribution system operatively coupled to the chamber, a high density plasma power source, a controller operatively coupled to the gas distribution system and the high density plasma power source and a memory coupled to the controller. The memory includes computer instructions embodied in a computer-readable format. The computer instructions comprise (i) instructions that control the gas distribution system to flow a process gas comprising a silane gas, an oxygen-containing source, an inert gas and a hydrogen-containing source that is either molecular hydrogen or a hydride gas that does not include silicon, boron or phosphorus and (ii) instructions that control the high density plasma source to form a plasma having an ion density of at least 1×1011 ions/cm3 from the process gas to deposit the silicon oxide layer over the substrate.

    摘要: A process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after depositing a layer of material over a substrate disposed in the chamber. In one embodiment the process comprises transferring the substrate out of the chamber; flowing a first gas into the substrate processing chamber and forming a plasma within the chamber from the first gas in order to heat the chamber; and thereafter, extinguishing the plasma, flowing an etchant gas into a remote plasma source, forming reactive species from the etchant gas and transporting the reactive species into the substrate processing chamber to etch the unwanted deposition build-up.
