    摘要: In a plasma enhanced physical vapor deposition of a material onto workpiece, a metal target faces the workpiece across a target-to-workpiece gap less than a diameter of the workpiece. A carrier gas is introduced into the chamber and gas pressure in the chamber is maintained above a threshold pressure at which mean free path is less than 5% of the gap. RF plasma source power from a VHF generator is applied to the target to generate a capacitively coupled plasma at the target, the VHF generator having a frequency exceeding 30 MHz. The plasma is extended across the gap to the workpiece by providing through the workpiece a first VHF ground return path at the frequency of the VHF generator.

    摘要: A method of performing physical vapor deposition of copper onto an integrated circuit in a vacuum chamber of a plasma reactor includes providing a copper target near a ceiling of the chamber, placing an integrated circuit wafer on a wafer support pedestal facing the target near a floor of the chamber, introducing a carrier gas into the vacuum chamber having an atomic weight substantially less than the atomic weight of copper, maintaining a target-sputtering plasma at the target to produce a stream comprising at least one of copper atoms and copper ions flowing from the target toward the wafer support pedestal for vapor deposition, maintaining a wafer-sputtering plasma near the wafer support pedestal by capacitively coupling plasma RF source power to the wafer-sputtering plasma, and accelerating copper ions of the wafer sputtering plasma in a direction normal to a surface of the wafer support pedestal.

    摘要: A method of fabricating multilayer interconnect structures on a semiconductor wafer begins by roughening the interior surface of a metal lid to a surface roughness in excess of SA 2000 with a reentrant surface profile, and installing the metal lid as the ceiling of a plasma clean reactor chamber having a wafer pedestal facing the interior surface of the ceiling. Conductive vias are formed in a dielectric layer of the semiconductor wafer, which are then covered with an overlying dielectric layer. High aspect ratio openings are etched through the overlying dielectric layer to the conductive via to expose a face of the conductive via. This step is followed by a preclean step for removing residue from the exposed face of each conductive via while capturing at least a portion of the residue on the roughened interior surface of the lid. This preclean step consists of: (1) placing the wafer on the wafer pedestal of the plasma clean reactor chamber and introducing an inert gas into the preclean reactor chamber; (2) coupling VHF plasma source power of 60 MHz or greater to the wafer pedestal with sufficient power to establish an etch rate on the order of 200-500 Å/min; and (3) coupling LF or HF plasma bias power of 13.56 MHz or less with sufficient power to realize the etch rate at the bottom surfaces of the high aspect ratio openings, and removing the wafer from the plasma clean reactor chamber.

    摘要: Physical vapor deposition and re-sputtering of a barrier layer in an integrated circuit is performed by providing a metal target near a ceiling of the chamber and a wafer support pedestal facing the target near a floor of the chamber. A process gas is introduced into said vacuum chamber. A target-sputtering plasma is maintained at the target to produce a stream of principally neutral atoms flowing from the target toward the wafer for vapor deposition. A wafer-sputtering plasma is maintained near the wafer support pedestal to produce a stream of sputtering ions toward the wafer support pedestal for re-sputtering. The sputtering ions are accelerated across a plasma sheath at the wafer in a direction normal to a surface of the wafer to render the sputter etching highly selective for horizontal surfaces.

    摘要: An ignition cable having a resistance wire helically wound around a strength member to form a conductive core. A very thin adhesive layer is applied over the conductive core and is overlaid with a semi-conductive layer of a cross-linked thermosetting material. The cross-linked thermosetting material is extruded over the adhesive layer to form a smooth surface. A layer of insulating material and a protective jacket are applied over the insulating layer. A braid may be added intermediate the insulating layer and the jacket to increase the mechanical strength of the ignition cable.
