  • Patent number: 8052885
    Abstract: Structural modification using electron beam activated chemical etch (EBACE) is disclosed. A target or portion thereof may be exposed to a gas composition of a type that etches the target when the gas composition and/or target are exposed to an electron beam. By directing an electron beam toward the target in the vicinity of the gas composition, an interaction between the electron beam and the gas composition etches a portion of the target exposed to both the gas composition and the electron beam. Structural modifications of the target may be conducted by means of etching due to interaction between the electron beam and gas composition.

  • Patent number: 8008207
    Abstract: A method for controlling chemical dry etching to improve smoothness of an etched surface is disclosed. Ions are implanted into a surface to form a volatilizable compound at a temperature low enough to avoid, reduce, or eliminate formation of three-dimensional structures of the volatilizable compound that might create the roughness at an etched surface of the volatilizable compound. The ions are applied in a sufficient energy to penetrate to a predetermined depth of material that is to be removed from the surface in an etching cycle, and in a sufficient dosage to achieve full formation of the volatilizable compound. The surface of the volatilizable compound is exposed to a gas composition for a time duration sufficient to completely etch the volatilizable compound.

  • Patent number: 7879730
    Abstract: Etch selectivity enhancement during electron beam activated chemical etch (EBACE) is disclosed. A target or portion thereof may be exposed to a gas composition of a type that etches the target when the gas composition and/or target are exposed to an electron beam. By directing an electron beam toward the target in the vicinity of the gas composition, an interaction between the electron beam and the gas composition etches a portion of the target exposed to both the gas composition and the electron beam. Selectivity of etching of the target due to interaction between the electron beam and gas composition may be enhanced in a number of ways.
