    Abstract: A diffusion barrier which reduces the diffusion of a copper feature into an oxygen containing polymer is provided by a copper metal alloy. The diffusion barrier is fabricated by coating a metal on a copper feature, heating the metal and copper feature to form an alloy of the copper feature and the metal, etching the non-alloyed metal which covers the alloy, and depositing an oxygen containing polymer on the alloy. Preferably the metal is aluminum and a copper aluminum alloy diffusion barrier is at least 300 angstroms thick and contains at least 8 percent aluminum on the surface in contact with the polymer.

    Abstract: Disclosed are a variety of self-supporting, multilayer carbon films that include a layer of both a non-diamond-like carbon, for example, graphitic or amorphous carbon (or a-C), and a layer of diamond-like carbon (DLC). A wide range of multilayer configurations may be constructed depending on the particular combination of properties desired in the final product including, for example, a tri-layer construction including a single DLC layer sandwiched between two layers of amorphous carbon. Also disclosed are example embodiments of methods for producing such composite multilayer films that include preparing an appropriate substrate to include a deposition surface of sufficient smoothness, applying a parting or release agent to the deposition surface, depositing a plurality of layer carbon layers including both an amorphous carbon layer and a DLC layer to form the composite carbon film and removing the composite carbon film from the substrate.

    Abstract: The present application is directed to siRNA-based silencing of the type II receptor of TGFβ. siRNAs that target this receptor abrogate the receptor protein and transcript, TGFβ-mediated processes such as fibronectin assembly and cell migration also are inhibited and the molecules of the invention are efficacious in reducing the inflammatory response and matrix deposition. These findings show that siRNAs can be successfully delivered both in vitro and in vivo to regulate the TGFβ type II receptor level and modulate wound response. Methods and compositions exploiting the findings of the present invention have a wide-ranging application, extending from treatment of disorders of the eye to other organs and tissues throughout the body.
