    摘要: The disclosure relates to methods and apparatus for depositing titanium films in a CVD system (10) using a heater heated to at least about 400°C at a pressure of about 1-10 torr in the reactor chamber (30), introducing a reactant gas and source gas at a reactant source gas flow ratio of less than about 250:1, and applying RF energy from a supply (5) to form a plasma. The present invention provides deposition rates up to 200 Å/minute on semiconductor substrates (36) from a titanium tetrachloride source, according to specific embodiments.

    摘要: The present invention provides methods and apparatus for cleaning unwanted metal deposits using a halogen-containing gas, such as a chlorine-containing gas in some embodiments, with RF energy at a temperature of at least 400°C to provide a plasma clean treatment. According to another embodiment, the present invention also provides a process of cleaning a deposition chamber (30) that includes steps of pressurizing the chamber to a first pressure with a non-reactive gas, reducing the first pressure to a cleaning process pressure, and flowing a reactive gas into the chamber at the cleaning process pressure such that the non-reactive gas outgasses from the interior space to minimise intrusion of the reactive gas into the interior space.
