  • Patent number: 10074534
    Abstract: Embodiments of the disclosure relate to deposition of a conformal carbon-based material. In one embodiment, the method comprises depositing a sacrificial dielectric layer over a substrate, forming patterned features on the substrate by removing portions of the sacrificial dielectric layer to expose an upper surface of the substrate, introducing a hydrocarbon source, a plasma-initiating gas, and a dilution gas into the processing chamber, generating a plasma in the processing chamber at a deposition temperature of about 80° C. to about 550° C. to deposit a conformal amorphous carbon layer on the patterned features and the exposed upper surface of the substrate, selectively removing the amorphous carbon layer from an upper surface of the patterned features and the upper surface of the substrate using an anisotropic etching process to provide the patterned features filled within sidewall spacers, and removing the patterned features formed from the sacrificial dielectric layer.

  • Patent number: 9721784
    Abstract: Embodiments of the invention relate to deposition of a conformal carbon-based material. In one embodiment, the method comprises depositing a sacrificial dielectric layer with a predetermined thickness over a substrate, forming patterned features on the substrate by removing portions of the sacrificial dielectric layer to expose an upper surface of the substrate, introducing a hydrocarbon source, a plasma-initiating gas, and a dilution gas into the processing chamber, wherein a volumetric flow rate of hydrocarbon source:plasma-initiating gas:dilution gas is in a ratio of 1:0.5:20, generating a plasma at a deposition temperature of about 300 C to about 500 C to deposit a conformal amorphous carbon layer on the patterned features and the exposed upper surface of the substrate, selectively removing the amorphous carbon layer from an upper surface of the patterned features and the upper surface of the substrate, and removing the patterned features.

  • Patent number: 8679987
    Abstract: Embodiments described herein relate to a method for processing a substrate. In one embodiment, the method includes introducing a gas mixture comprising a hydrocarbon source and a diluent gas into a deposition chamber located within a processing system, generating a plasma from the gas mixture in the deposition chamber at a temperature between about 200° C. and about 700° C. to form a low-hydrogen content amorphous carbon layer on the substrate, transferring the substrate into a curing chamber located within the processing system without breaking vacuum, and exposing the substrate to UV radiation within the curing chamber at a curing temperature above about 200° C.

  • Patent number: 8097082
    Abstract: A method and apparatus for adjust local plasma density during a plasma process. One embodiment provides an electrode assembly comprising a conductive faceplate having a nonplanar surface. The nonplanar surface is configured to face a substrate during processing and the conductive faceplate is disposed so that the nonplanar surface is opposing a substrate support having an electrode. The conductive faceplate and the substrate support form a plasma volume. The nonplanar surface is configured to adjust electric field between the conductive plate and the electrode by varying a distance between the conductive plate and the electrode.
