摘要： In a plasma reactor having an RF plasma source power applicator at its ceiling, an integrally formed grid liner includes a radially extending plasma confinement ring and an axially extending side wall liner. The plasma confinement ring extends radially outwardly near the plane of a workpiece support surface from a pedestal side wall, and includes an annular array of radial slots, each of the slots having a narrow width corresponding to an ion collision mean free path length of a plasma in the chamber. The side wall liner covers an interior surface of the chamber side wall and extends axially from a height near a height of said workpiece support surface to the chamber ceiling.

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 method for processing a workpiece in a plasma reactor chamber includes coupling RF power at a first VHF frequency f1 to a plasma via one of the electrodes of the chamber, and providing a center ground return path for RF current passing directly between the ceiling electrode and the workpiece support electrode for the frequency f1. The method further includes providing a variable height edge ground annular element and providing a ground return path through the edge ground annular element for the frequency f1. The method controls the uniformity of plasma ion density distribution by controlling the distance between the variable height edge ground annular element and one of: (a) height of ceiling electrode or (b) height of workpiece support electrode.

摘要： A reactor is provided for removing polymer from a backside of a workpiece. The reactor includes a vacuum chamber having a ceiling, a floor and a cylindrical side wall. A workpiece support apparatus within the chamber is configured to support a workpiece thereon, so that the workpiece has its front side facing the ceiling. The support apparatus leaves at least an annular periphery of the backside of the workpiece exposed. A confinement member defines a narrow gap with the outer edge of the workpiece, the narrow gap being on the order of about 1% of workpiece diameter, the narrow gap corresponding to a boundary dividing the chamber between an upper process zone and a lower process zone. A vacuum pump is coupled to the lower process zone. A lower external plasma-generating chamber introduces a plasma by-product into the lower process zone and a supply of a polymer etch precursor gas coupled to the lower external plasma-generating chamber. An upper external plasma-generating chamber is coupled to introduce a plasma by-product into the upper process zone and a supply of a scavenger species precursor gas coupled to the upper external plasma-generating chamber.
