    摘要: A turbine blade rotor assembly is disclosed for a gas turbine engine. The assembly includes a rotor having nickel alloy turbine blades secured thereto. Each of the blades includes a root and an airfoil. The roots are supported by the rotor. A ceramic matrix composite platform separate from the turbine blades is supported between each pair of the turbine blades adjacent to the airfoils. In another example, the airfoil includes a perimeter. A shroud having an aperture receives the airfoil with a single shroud substantially surrounding the airfoil at the perimeter. In one example, the turbine blade includes high and low pressure sides opposite one another that extend from a tip to a root. The airfoil is free from any protrusions extending from the high and low pressure sides on a portion of the blade axially outward from the root.

    摘要: A method for etching features in an etch layer is provided. A patterned photoresist mask is formed over the etch layer with photoresist features with sidewalls wherein the sidewalls of the photoresist features have irregular profiles along depths of the photoresist features. The irregular profiles along the depths of the photoresist features of the sidewalls of the photoresist features are corrected comprising at least one cycle, where each cycle comprises a sidewall deposition phase and a profile shaping phase. Feature is etched into the etch layer through the photoresist features. The mask is removed.

    摘要: A method for etching a feature in a low-k dielectric layer through a photoresist etch mask over a substrate. A gas-modulated cyclic stripping process is performed for more than three cycles for stripping a single photoresist mask. Each cycle of the gas-modulated cyclic stripping process comprises performing a protective layer formation phase and a stripping phase. The protective layer forming phase using first gas chemistry with a deposition gas chemistry, wherein the protective layer forming phase is performed in about 0.005 to 10 seconds for each cycle. The performing the stripping phase for stripping the photoresist mask using a second gas chemistry using a stripping gas chemistry, where the first gas chemistry is different than the second gas chemistry, wherein the etching phase is performed in about 0.005 to 10 seconds for each cycle.
