    摘要： The present invention provides techniques for coupling radio-frequency (RF) power to a metal plate in a ceramic pedestal. Perforations in the metal plate allow ceramic-to-ceramic bonding through the metal plate. The power from an RF power feed is distributed to the perforated metal plate via several electrodes that are spaced away from the centerline of the RF power feed, thus splitting power distribution. A ceramic bonding disk between the metal plate and the RF power feed provides mechanical support for the metal plate and a ceramic body to bond to through the perforations, thus reducing cracking of the metal plate and the surrounding ceramic material.

    摘要： The invention relates to an apparatus and process for the vaporization of liquid precursors and deposition of a film on a suitable substrate. In one aspect, an apparatus and process for the control of a gas flowed through a gas feedthrough in a substrate processing chamber and system is provided. In another aspect, a deposition chamber is provided for depositing BST and other materials which require vaporization, especially low volatility precursors which are transported as a liquid to a vaporizer to be converted to vapor phase and which must be transported at elevated temperatures to prevent unwanted condensation on chamber components. The chamber comprises a series of heated temperature controlled internal liners, such as a heated gas feedthrough.

    摘要： The present invention provides an approach which provides an increase in the number of usable substrates with a film, such as titanium nitride, deposited thereon at a sufficient deposition rate and where the film meets uniformity and resistivity specifications as well as providing good step coverage. In accordance with an embodiment, the present invention provides an apparatus for substrate processing. The apparatus circulates a heat exchange medium through a passage in a chamber body of a vacuum chamber, and heats a heater pedestal having a surface for supporting the substrate to a heater temperature. The heat exchange medium has a heat exchange temperature of about 60.degree. C. or less. The the apparatus also flows a gas into the chamber at a flow rate to deposit a film on a substrate, where the flow rate provides an effective temperature of the substrate lower than the heater temperature and where the film meets uniformity and resistance specifications after deposition onto a number of substrates. This number is less than twenty-five, in some embodiments, and less than ten in other embodiments. The use of the present invention thus avoids the discarding of the initial hundreds of processed substrates not meeting specifications that is typically experienced with the prior art processes.

    摘要： The present invention provides systems, methods and apparatus for depositing titanium films at rates up to 200 .ANG./minute on semiconductor substrates from a titanium tetrachloride source. In accordance with an embodiment of the invention, a ceramic heater assembly with an integrated RF plane for bottom powered RF capability allows PECVD deposition at a temperature of at least 400.degree. C. for more efficient plasma treatment. A thermal choke isolates the heater from its support shaft, reducing the thermal gradient across the heater to reduce the risk of breakage and improving temperature uniformity of the heater. A deposition system incorporates a flow restrictor ring and other features that allow a 15 liters/minute flow rate through the chamber with minimal backside deposition and minimized deposition on the bottom of the chamber, thereby reducing the frequency of chamber cleanings, and reducing clean time and seasoning. Deposition and clean processes are also further embodiments of the present invention.
