  • Patent number: 8753989
    Abstract: High tensile stress in a deposited layer, such as a silicon nitride layer, may be achieved utilizing one or more techniques employed either alone or in combination. In one embodiment, a silicon nitride film having high tensile stress may be formed by depositing the silicon nitride film in the presence of a porogen. The deposited silicon nitride film may be exposed to at least one treatment selected from a plasma or ultraviolet radiation to liberate the porogen. The silicon nitride film may be densified such that a pore resulting from liberation of the porogen is reduced in size, and Si—N bonds in the silicon nitride film are strained to impart a tensile stress in the silicon nitride film. In another embodiment, tensile stress in a silicon nitride film may be enhanced by depositing a silicon nitride film in the presence of a nitrogen-containing plasma at a temperature of less than about 400° C., and exposing the deposited silicon nitride film to ultraviolet radiation.

  • Patent number: 8445075
    Abstract: Methods of processing films on substrates are provided. In one aspect, the methods comprise treating a patterned low dielectric constant film after a photoresist is removed from the film by depositing a thin layer comprising silicon, carbon, and optionally oxygen and/or nitrogen on the film. The thin layer provides a carbon-rich, hydrophobic surface for the patterned low dielectric constant film. The thin layer also protects the low dielectric constant film from subsequent wet cleaning processes and penetration by precursors for layers that are subsequently deposited on the low dielectric constant film.
