  • Patent number: 7556718
    Abstract: This invention relates to ionized PVD processing of semiconductor wafers and provides conditions for highly uniform deposition-etch process sequence and coverage capabilities of high aspect ratio (HAR) features within a single processing chamber. A plasma is generated and maintained by an inductively coupled plasma (ICP) source. A deposition process step is performed in which metal vapor is produced from a target of a PVD source. Location and sputter efficiency at the target surface is enhanced by moving a magnet pack to create a traveling or sweeping magnetic field envelope. The target is energized from a DC power supply and pressures effective for an efficient thermalization of the sputtered atoms (30<p<100 mTorr) are maintained in the chamber during deposition. A uniform thickness of the metal on the wafer is produced within each magnet sweeping cycle.

  • Patent number: 7464662
    Abstract: An inductively coupled plasma source is provided with a compact inductive element that is configured to produce a spatially distributed plasma particularly suitable for processing large scale wafers. The element in its preferred embodiment is formed of a sheet material for compactness and ease in configuring. The element is located outside of a dielectric wall or window of a processing chamber, generally congruent to the dielectric wall or window, formed of one or more layers or loops. The conductor provides a conductive path around each loop that has a serpentine or oscillating configuration that renders the path around each loop greater than the circumference of the element. The path is so shaped by cutouts along the side edges of the element. The conductor is formed of alternating sections of large and small aspect ratio, defined as the width across the path to the thickness of the sheet. The sections are also defined by cutouts in the sheet.

  • Publication number: 20080242065
    Abstract: A manufacturing method and apparatus for IC fabrication controls the ion angular distribution at the surface of a wafer with electrodes in a wafer support that produce electric fields parallel to the wafer surface without disturbing plasma parameters beyond the wafer surface. The ion angular distribution function (IADF) at the wafer surface is controlled for better feature coverage or etching. Grid structure is built into the substrate holder within the coating at the top of the holder. The grid components are electrically biased to provide electric fields that combine with the sheath field to distribute the ion incidence angles from the plasma sheath onto the wafer. The grid can be dynamically biased or phased to control uniformity of the effects.

  • Publication number: 20080236491
    Abstract: Different gases are separately exposed to RF energy in different zones in inlets to a processing chamber. Plasma is activated in the gases in each of the zones separately and the activated gases are then introduced into the plasma processing chamber where they may undergo mutual interaction within a processing zone. Control of the active species distribution within the processing chamber is provided by control of the energizing of the gases in the separate inlet zones before they are combined in the processing zone. An ICP source energizes gas in each zone through an antenna having one or more conductors, each of which is coupled to a plurality of the zones. This allows gases to be brought together in their active states, rather than being combined and then activated, and allows the same or different parameters to be applied in different inlet zones.

  • Patent number: 7426900
    Abstract: An integrated electrostatic inductively-coupled (i-ESIC) device is provided for plasma processing that may be used as a primary or secondary source for generating a plasma to prepare substrates for, and to process substrates by applying, dielectric and conductive coatings. The i-ESIC device is practical for processing advanced semiconductor devices and integrated circuits that require uniform and dense plasma. The invention may be embodied in an apparatus that contains a substrate support, typically including an electrostatic chuck, that controls ion energy by capacitively coupling RF power to the plasma and generating voltage bias on the wafer relative to the plasma potential. An integrated inductive coupling element is provided at the perimeter of the substrate support that increases plasma density at the perimeter of the wafer, compensating for the radial loss of charged particles toward chamber walls, to produce uniform plasma density above the processed wafer.

  • Publication number: 20070068795
    Abstract: The uniformity of a plasma distribution having a tendency to peak toward the axis of a processing chamber is improved by positioning a hollow body on the chamber axis with an open end facing the processing space. The hollow body controls the distribution of the plasma away from the center and allows plasma at the center. The geometry of the hollow body can be optimized to render the plasma uniform for given conditions. In combined deposition and etch processes, such as simultaneous and sequential etch and iPVD processes, the hollow body provides for a uniform plasma for etching while allowing deposition parameters to be optimized for deposition.
