  • Patent number: 7629272
    Abstract: Processes for forming porous low k dielectric materials from low k dielectric films containing a porogen material include exposing the low k dielectric film to ultraviolet radiation. In one embodiment, the film is exposed to broadband ultraviolet radiation of less than 240 nm for a period of time and intensity effective to remove the porogen material. In other embodiments, the low k dielectric film is exposed to a first ultraviolet radiation pattern effective to increase a crosslinking density of the film matrix while maintaining a concentration of the porogen material substantially the same before and after exposure to the first ultraviolet radiation pattern. The low k dielectric film can be then be processed to form a metal interconnect structure therein and subsequently exposed to a second ultraviolet radiation pattern effective to remove the porogen material from the low k dielectrics film and form a porous low k dielectric film.

  • Publication number: 20090277871
    Abstract: Processes for stripping high dose ion implanted photoresist while minimizing substrate loss. The processes generally include passivation of the substrate surface before and/or during a plasma mediated stripping process. By passivating the substrate surface before and/or during the plasma mediated stripping process, oxidation is substantially reduced during plasma stripping thereby leading to reduced substrate loss.

  • Publication number: 20070228008
    Abstract: A system and method for removing photoresist or other organic compounds from semiconductor wafers is provided. Non-fluorinated reactant gases (O2, H2, H2O, N2 etc.) are activated in a quartz tube by a medium pressure surface wave discharge. As the plasma jet impinges on a substrate, volatile reaction products (H2O, CO2, or low molecular weight hydrocarbons) selectively remove the photoresist from the surface. The medium pressure also enables high gas temperatures that provide an effective source of heat in the reactive zone on the wafer that enhances etch rates and provides a practical means of removing ion implanted photoresist.
