    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 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 for implanting ions in a surface layer of a workpiece includes placing the workpiece on a workpiece support in a chamber with the surface layer being in facing relationship with a ceiling of the chamber, thereby defining a processing zone between the workpiece and the ceiling, and introducing into the chamber a process gas which includes the species to be implanted in the surface layer of the workpiece. The method further includes generating from the process gas a plasma by inductively coupling RF source power into the processing zone from an RF source power generator through an inductively coupled RF power applicator, and applying an RF bias from an RF bias generator to the workpiece support.
