    摘要: A process for conformally doping through the vertical and horizontal surfaces of a 3-dimensional vertical transistor in a semiconductor-on-insulator structure employs an RF oscillating torroidal plasma current to perform either conformal ion implantation, or conformal deposition of a dopant-containing film which can then be heated to drive the dopants into the transistor. Some embodiments employ both conformal ion implantation and conformal deposition of dopant containing films, and in those embodiments in which the dopant containing film is a pure dopant, the ion implantation and film deposition can be performed simultaneously.

    摘要: A system for processing a workpiece includes a plasma immersion ion implantation reactor with an enclosure having a side wall and a ceiling and defining a chamber, and a workpiece support pedestal within the chamber having a workpiece support surface facing the ceiling and defining a process region extending generally across the wafer support pedestal and confined laterally by the side wall and axially between the workpiece support pedestal and the ceiling. The enclosure has at least a first pair of openings at generally opposite sides of the process region, and a first hollow conduit outside the chamber having first and second ends connected to respective ones of the first pair of openings, so as to provide a first reentrant path extending through the conduit and across the process region. The reactor further includes a gas distribution apparatus on or near an interior surface of the reactor for introducing a process gas containing a first species to be ion implanted into a surface layer of the workpiece, and a first RF plasma source power applicator for generating a plasma in the chamber. The system further includes a second wafer processing apparatus and a wafer transfer apparatus for transferring the workpiece between the plasma immersion implantation rector and the second wafer processing apparatus.

    摘要: A lift pin assembly for use in a reactor for processing a workpiece includes plural lift pins extending generally parallel with a lift direction, each of the plural lift pins having a top end for supporting a workpiece and a bottom end. A lift table faces the bottom ends of the pins and is translatable in a direction generally parallel with the lift direction. A small force detector senses a force exerted by the lift pins that is sufficiently large to indicate a chucked wafer and sufficiently small to avoid dechucking a wafer. A large force detector senses a force exerted by the lift pins in a range sufficient to de-chuck the wafer.

    摘要: A method of processing a thin film structure on a semiconductor substrate using an optically writable mask, the method includes placing the substrate in a reactor chamber, the substrate having on its surface a target layer to be exposed to a light source in accordance with a predetermined pattern, depositing an optically writable carbon-containing mask layer on the substrate by (a) introducing a carbon-containing process gas into the chamber, (b) generating a reentrant toroidal RF plasma current in a reentrant path that includes a process zone overlying the workpiece by coupling plasma RF source power to an external portion of the reentrant path, (c) coupling RF plasma bias power or bias voltage to the workpiece. The method further includes optically writing on the carbon-containing mask layer in accordance with the predetermined pattern with writing light of a characteristic suitable for transforming the transparency or opacity of the optically writable mask layer and exposing through the mask layer the target layer with reading light of a characteristic different from that of the writing light.
