    摘要: An apparatus for etching a dielectric layer contained by a substrate is provided. An etch reactor comprises a top electrode and a bottom electrode. An etch gas source supplies an etch gas into the etch reactor. A first Radio Frequency (RF) source generates a first RF power with a first frequency and supplies the first RF power into the etch reactor, whereas the first frequency is between 100 kilo Hertz (kHz) and 600 kHz. A second RF source generates a second RF power with a second frequency and supplies the second RF power into the etch reactor, whereas the second frequency is at least 10 mega Hertz (MHz).

    摘要: A method for etching an ultra high aspect ratio feature in a dielectric layer through a carbon based mask is provided. The dielectric layer is selectively etched with respect to the carbon based mask, wherein the selective etching provides a net deposition of a fluorocarbon based polymer on the carbon based mask. The selective etch is stopped. The fluorocarbon polymer is selectively removed with respect to the carbon based mask, so that the carbon based mask remains, using a trimming. The selectively removing the fluorocarbon polymer is stopped. The dielectric layer is again selectively etched with respect to the carbon based mask, wherein the second selectively etching provides a net deposition of a fluorocarbon based polymer on the carbon based mask.

    摘要: Methods of etching a carbon-rich layer on organic photoresist overlying an inorganic layer can utilize a process gas including CxHyFz, where y≧x and z≧0, and one or more optional components to generate a plasma effective to etch the carbon-rich layer with low removal of the inorganic layer. The carbon-rich layer can be removed in the same processing chamber, or alternatively can be removed in a different processing chamber, as used to remove the bulk photoresist.
