    摘要: A method and apparatus for confining a plasma are provided herein. In one embodiment, an apparatus for confining a plasma includes a substrate support and a magnetic field forming device for forming a magnetic field proximate a boundary between a first region disposed at least above the substrate support, where a plasma is to be formed, and a second region, where the plasma is to be selectively restricted. The magnetic field has b-field components perpendicular to a direction of desired plasma confinement that selectively restrict movement of charged species of the plasma from the first region to the second region dependent upon the process conditions used to form the plasma.

    摘要: Methods for forming an ultra thin structure. The method includes a polymer deposition and etching process. In one embodiment, the methods may be utilized to form fabricate submicron structure having a critical dimension less than 30 nm and beyond. The method further includes a multiple etching processes. The processes may be varied to meet different process requirements. In one embodiment, the process gently etches the substrate while shrinking critical dimension of the structures formed within the substrate. The dimension of the structures may be shank by coating a photoresist like polymer to sidewalls of the formed structure, but substantially no polymer accumulation on the bottom surface of the formed structure on the substrate. The embodiments described herein also provide high selectivity in between each layers formed on the substrate during the fabricating process and preserving a good control of profile formed within the structure.
