    摘要: Embodiments described herein provide methods and apparatus for treating a magnetic substrate having an imprinted, oxygen-reactive mask formed thereon by implanting ions into a magnetically active surface of the magnetic substrate through the imprinted oxygen-reactive mask, wherein the ions do not reduce the oxygen reactivity of the mask, and removing the mask by exposing the substrate to an oxygen-containing plasma. The mask may be amorphous carbon, through which carbon-containing ions are implanted into the magnetically active surface. The carbon-containing ions, which may also contain hydrogen, may be formed by activating a mixture of hydrocarbon gas and hydrogen. A ratio of the hydrogen and the hydrocarbon gas may be selected or adjusted to control the ion implantation.

    摘要: A method and apparatus for removing excess dopant from a doped substrate is provided. In one embodiment, a substrate is doped by surfaced deposition of dopant followed by formation of a capping layer and thermal diffusion drive-in. A reactive etchant mixture is provided to the process chamber, with optional plasma, to etch away the capping layer and form volatile compounds by reacting with excess dopant. In another embodiment, a substrate is doped by energetic implantation of dopant. A reactive gas mixture is provided to the process chamber, with optional plasma, to remove excess dopant adsorbed on the surface and high-concentration dopant near the surface by reacting with the dopant to form volatile compounds. The reactive gas mixture may be provided during thermal treatment, or it may be provided before or after at temperatures different from the thermal treatment temperature. The volatile compounds are removed. Substrates so treated do not form toxic compounds when stored or transported outside process equipment.

    摘要: 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.
