  • Patent number: 9773675
    Abstract: Embodiments of the present disclosure relate to precision material modification of three dimensional (3D) features or advanced processing techniques. Directional ion implantation methods are utilized to selectively modify desired regions of a material layer to improve etch characteristics of the modified material. For example, a modified region of a material layer may exhibit improved etch selectivity relative to an unmodified region of the material layer. Methods described herein are useful for manufacturing 3D hardmasks which may be advantageously utilized in various integration schemes, such as fin isolation and gate-all-around, among others. Multiple directional ion implantation processes may also be utilized to form dopant gradient profiles within a modified layer to further influence etching processes.

  • Patent number: 9534289
    Abstract: Plasma process chambers employing distribution grids having focusing surfaces thereon enabling angled fluxes to reach a substrate, and associated methods are disclosed. A distribution grid is disposed in a chamber between the plasma and a substrate. The distribution grid includes a first surface facing the substrate and a focusing surface facing the plasma. A passageway extends through the distribution grid, and is sized with a width to prevent the plasma sheath from entering therein. By positioning the focusing surface at an angle other than parallel to the substrate, an ion flux from the plasma may be accelerated across the plasma sheath and particles of the flux pass through the passageway to be incident upon the substrate. In this manner, the angled ion flux may perform thin film deposition and etch processes on sidewalls of features extending orthogonally from or into the substrate, as well as angled implant and surface modification.

  • Patent number: 9520267
    Abstract: The angular ion distribution in plasma processing is controlled using a bias voltage frequency. In one example, a plasma containing gas ions is generated in a plasma chamber. The plasma sheath is modified using an aperture disposed between the plasma sheath and the workpiece so that the plasma sheath takes a shape above the aperture. An oscillating radio frequency bias voltage is generated and applied to a workpiece holder. The workpiece holder applies the bias voltage to the workpiece to generate a workpiece bias voltage with respect to the plasma to attract ions across the plasma sheath toward the workpiece. The aperture and the frequency of the bias voltage control an angle at which the ions are attracted toward the workpiece.

  • Patent number: 9502258
    Abstract: A method of anisotropically dry-etching exposed substrate material on a patterned substrate is described. The patterned substrate has a gap formed in a single material made from, for example, a silicon-containing material or a metal-containing material. The method includes directionally ion-implanting the patterned structure to implant the bottom of the gap without implanting substantially the walls of the gap. Subsequently, a remote plasma is formed using a fluorine-containing precursor to etch the patterned substrate such that either (1) the walls are selectively etched relative to the floor of the gap, or (2) the floor is selectively etched relative to the walls of the gap. Without ion implantation, the etch operation would be isotropic owing to the remote nature of the plasma excitation during the etch process.
