    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 measuring ion dose in a plasma immersion ion implantation reactor during ion implantation of a selected species into a workpiece includes placing the workpiece on a pedestal in the reactor and feeding into the reactor a process gas comprising a species to be implanted into the workpiece, and then coupling RF plasma source power to a plasma in the reactor. It further includes coupling RF bias power to the workpiece by an RF bias power generator that is coupled to the workpiece through a bias feedpoint of the reactor and measuring RF current at the feedpoint to generate a current-related value, and then integrating the current-related over time to produce an ion implantation dose-related value.

    摘要: A valve system having high maximum gas flow rate and fine control of gas flow rate, includes a valve housing for blocking gas flow through a gas flow path, a large area opening through said housing having a first arcuate side wall and a small area opening through said housing having a second arcuate side wall, and respective large area and small area rotatable valve flaps in said large area and small area openings, respectively, and having arcuate edges congruent with said first and second arcuate side walls, respectively and defining therebetween respective first and second valve gaps. The first and second valve gaps are sufficiently small to block flow of a gas on one side of said valve housing up to a predetermined pressure limit, thereby obviating any need for O-rings.
