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.
