  • Publication number: 20170256448
    Abstract: Described are methods for controlling the doping of metal nitride films such as TaN, TiN and MnN. The temperature during deposition of the metal nitride film may be controlled to provide a film density that permits a desired amount of doping. Dopants may include Ru, Cu, Co, Mn, Mo, Al, Mg, Cr, Nb, Ta, Ti and V. The metal nitride film may optionally be exposed to plasma treatment after doping.

  • Patent number: 8470126
    Abstract: An apparatus for etching features in an etch layer is provided. A plasma processing chamber is provided, comprising a chamber wall, a chuck, a pressure regulator, an electrode or coil, a gas inlet, and a gas outlet. A gas source comprises a fluorine free deposition gas source and an etch gas source. A controller comprises at least one processor and computer readable media, comprising computer readable code for providing a conditioning for a patterned pseudo-hardmask, wherein the conditioning comprises computer readable code providing a fluorine free deposition gas comprising a hydrocarbon gas, computer readable code for forming a plasma, computer readable code for providing a bias less than 500 volts, and computer readable code for forming a deposition on top of the patterned pseudo-hardmask, computer readable code for etching the etch layer, and computer readable code for cyclically repeating the conditioning and etching at least twice.

  • Patent number: 8329585
    Abstract: A method for reducing line width roughness (LWR) of a feature in an etch layer below a patterned photoresist mask having mask features is provided. The method includes (a) non-etching plasma pre-etch treatment of the photoresist mask, and (b) etching of a feature in the etch layer through the pre-treated photoresist mask using an etching gas. The non-etching plasma pre-etch treatment includes (a1) providing a treatment gas containing H2 and COS, (a2) forming a plasma from the treatment gas, and (a3) stopping the treatment gas.
