    摘要: A method for plasma processing a high-k layer includes providing a substrate having a high-k layer formed thereon, on a substrate holder in a process chamber, and creating a plasma in the process chamber to thereby expose the high-k layer to the plasma. RF power is applied to the substrate holder, the RF power having a characteristic to reduce a rate of formation of an oxide interface layer located between the substrate and the high-k layer. A device includes a feature etched in a high-k layer. The etch profile of the device can include a reduced bird's beak, and a surface of the substrate in an etched region can be substantially coplanar with a substrate under a non-etched area.

    摘要: A method and system is described for etching a tunable etch resistant anti-reflective (TERA) coating. The TERA coating can be utilized, for example, as a hard mask, or as an anti-reflective coating for complementing a lithographic structure. The TERA coating can include a structural formula R:C:H:X, wherein R is selected from the group consisting of Si, Ge, B, Sn, Fe, Ti, and combinations thereof, and wherein X is not present or is selected from the group consisting of one or more of O, N, S, and F. During the formation of a structure in a film stack, a pattern is transferred to the TERA coating using dry plasma etching having a SF6-based etch chemistry.
