  • Publication number: 20050008980
    Abstract: A method of developing a polymeric film without the need for a water rinse step. An object having a surface supporting a polymeric film is placed onto a support region within a pressure chamber. A fluid and developer is introduced into the pressure chamber and the object is processed at supercritical conditions to develop the polymeric film such that the polymeric film is not substantially deformed. The pressure chamber is then vented.

  • Patent number: 6730605
    Abstract: A method to redistribute solid copper deposited by PVD on a wafer topography. The deposited copper is solubilized in a fluid for redistribution. The copper redistribution prevents inherent nonuniformity of the deposited copper film thickness by improving the uniformity of thickness of the copper film on the covered surfaces, such as vertical and bottom surfaces. The method provides the advantages of good adhesion and good grain growth and orientation that are achieved with copper deposited by PVD, and also provides the good step coverage as achieved with copper deposited by CVD.

  • Patent number: 6440494
    Abstract: An in-situ method for synthesis of a vapor type of copper or other metal precursor from a solid source of metal in an oxidation state of 1 or greater The solid source is localized above the wafer and its temperature is controlled independently from the wafer temperature. The solid source may be located, for example, in a showerhead. A metal precursor vapor is produced, and this vapor is drawn onto the wafer, allowing deposition to occur on the wafer and a solid thin metal film to form on the wafer. The invention overcomes the problem of low partial pressure of copper precursors in copper CVD.
