    摘要： The present invention provides a method of forming a semiconductor structure having an ultra low-K dielectric material that adheres well to the substrate. The method includes depositing a low-K material on the top surface of a substrate at a low temperature of no more than 250° by a CVD or spin-on process. The dielectric material is then cured by placing the substrate with the dielectric film in an environment where the temperature is regulated at about 400° or less as the dielectric film is being subjected to a plasma treatment or an E-beam treatment or UV treatment. The environment may further include one or more gases or a mixture of gases selected from the group consisting of H2, N2, NH3, CO2, all hydride gases and a mixture of these gases.

    摘要： A method of protecting a low k dielectric layer that is preferably comprised of a material containing Si, O, C, and H is described. The dielectric layer is subjected to a gas plasma that is generated from a CXHY gas which is preferably ethylene. Optionally, hydrogen may be added to the CXHY gas. Another alternative is a two step plasma process involving a first plasma treatment of CXHY or CXHY combined with H2 and a second plasma treatment with H2. The modified dielectric layer provides improved adhesion to anti-reflective layers and to a barrier metal layer in a damascene process. The modified dielectric layer also has a low CMP rate that prevents scratch defects and an oxide recess from occurring next to the metal layer on the surface of the damascene stack. The plasma treatments are preferably done in the same chamber in which the dielectric layer is deposited.
