Patent number: 7556718Abstract: 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.Type: GrantFiled: June 22, 2004Date of Patent: July 7, 2009Assignee: Tokyo Electron LimitedInventor: Jozef Brcka

Patent number: 7464662Abstract: 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.Type: GrantFiled: January 28, 2004Date of Patent: December 16, 2008Assignee: Tokyo Electron LimitedInventor: Jozef Brcka

Publication number: 20080242065Abstract: 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.Type: ApplicationFiled: March 29, 2007Publication date: October 2, 2008Applicant: Tokyo Electron LimitedInventor: Jozef Brcka

Publication number: 20080236491Abstract: 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.Type: ApplicationFiled: March 30, 2007Publication date: October 2, 2008Applicant: TOKYO ELECTRON LIMITEDInventor: Jozef Brcka
