  • Publication number: 20110151590
    Abstract: A method, a system and a computer readable medium for integrated in-vacuo repair of low-k dielectric thin films damaged by etch and/or strip processing. A repair chamber is integrated onto a same platform as a plasma etch and/or strip chamber to repair a low-k dielectric thin film without breaking vacuum between the damage event and the repair event. UV radiation may be provided on the integrated etch/repair platform in any combination of before, after, or during the low-k repair treatment to increase efficacy of the repair treatment and/or stability of repair.

  • Publication number: 20100095979
    Abstract: A remote plasma process for removing unwanted deposition build-up from one or more interior surfaces of a substrate processing chamber after processing a substrate disposed in the substrate processing chamber. In one embodiment, the substrate is transferred out of the substrate processing chamber and a flow of a fluorine-containing etchant gas is introduced into a remote plasma source where reactive species are formed. A continuous flow of the reactive species from the remote plasmas source to the substrate processing chamber is generated while a cycle of high and low pressure clean steps is repeated. During the high pressure clean step, reactive species are flown into the substrate processing chamber while pressure within the substrate processing chamber is maintained between 4-15 Torr.

  • Publication number: 20090208880
    Abstract: Method and systems for patterning a hardmask film using ultraviolet light is disclosed according to one embodiment of the invention. Embodiments of the present invention alleviate the processing problem of depositing and etching photoresist in order to produce a hardmask pattern. A hardmask layer, such as, silicon oxide, is first deposited on a substrate within a deposition chamber. In some cases, the hardmask layer is baked or annealed following deposition. After which, portions of the hardmask layer are exposed with ultraviolet light. The ultraviolet light produces a pattern of exposed and unexposed portions of hardmask material. Following the exposure, an etching process, such as a wet etch, may occur that removes the unexposed portions of the hardmask. Following the etch, the hardmask may be annealed, baked or subjected to a plasma treatment.
