  • Publication number: 20080003778
    Abstract: A method of bonding two substrates and a corresponding bonded structure are described. The method includes forming a first nanostructure layer comprising nanostructures on a first substrate. A second substrate is contacted with the first nanostructure layer. The first nanostructure layer is heated at a heating temperature below a melting temperature of the first and second substrates. The first nanostructure layer is cooled after heating the nanostructure layer such that the first substrate is bonded to the second substrate.

  • Patent number: 7285842
    Abstract: Structures employing siloxane epoxy polymers as diffusion barriers adjacent conductive metal layers are disclosed. The siloxane epoxy polymers exhibit excellent adhesion to conductive metals, such as copper, and provide an increase in the electromigration lifetime of metal lines. In addition, the siloxane epoxy polymers have dielectric constants less then 3, and thus, provide improved performance over conventional diffusion barriers.

  • Patent number: 7019386
    Abstract: Semiconductor devices employing siloxane epoxy polymers as low-? dielectric films are disclosed. The devices include a semiconductor substrate, one or more metal layers or structures and one or more dielectric films, wherein at least one dielectric film in the devices is a siloxane epoxy polymer. Use of siloxane epoxy polymers is advantageous, in part, because the polymers adhere well to metals and have dielectric constants as low as 1.8. Thus, the disclosed semiconductor devices offer much better performance than devices fabricated using conventional dielectric materials. Furthermore, the siloxane epoxy polymer dielectrics are fully curable at low temperatures, exhibit low leakage currents, and remain stable at temperatures greater than 400° C.
