Patent number: 6423976Abstract: An ion implanter employs two three gap rf accelerator stages to boost the implant energy after mass selection. The electrodes of the accelerator stages have slit-shaped apertures that accommodate high beam current, when the accelerator is in drift mode. By particular choice of the parameters of the accelerator, each stage of the accelerator produces accelerated ions having a relatively small energy spread, even though the acceptance range of the accelerator stage extends over a substantial phase angle of the applied rf voltage. The resulting accelerator is flexible, permitting a wide variation of output energies with good beam dynamics. Ion bunches from the first three gap stage are caused to have the correct flight time to reach the second stage for acceleration by adjusting the speed of the ions while maintaining the rf phase of the fields in the two stages locked to fixed values.Type: GrantFiled: May 28, 1999Date of Patent: July 23, 2002Assignee: Applied Materials, Inc.Inventors: Hilton F.

Patent number: 5907158Abstract: Ion implanter having at least two independent ion generating systems coupled to a single scanning end station. In a preferred embodiment one of the ion generating systems generates ions approximately in the 3-80 keV range and the other system generates ions approximately in the 80-3,000 keV range. The scanning end station may be employ magnetic, electrostatic, or mechanical scanning. This invention has particular relevance for the controlled doping of semiconducting materials and flat panel displays units in which doping may be needed for the production of micro-electronic devices, the sub-circuit crystal damage that is useful for gettering unwanted impurity atoms and for the development of etch pits in flat panel displays. The disclosed apparatus makes possible a variety of chained implants at different energies using the same mask.Type: GrantFiled: May 14, 1997Date of Patent: May 25, 1999Assignee: Ebara CorporationInventors: Mehran Nasser-Ghodsi, Andrew Wittkower, Hilton F.

Patent number: 5504341Abstract: An ion beam accelerator and an ion implantation system including a plurality of spaced apart electrodes, including at least one active electrode, and a pair of oppositely wound coils disposed within the shield, the coils being in parallel, having respective terminating ends electrically coupled together in pairs, the end regions of the two coils being positioned relative to each other for flow of flux between the coils so that, when the coils are energized, magnetic fields produced by the coils are reinforced within the coils and are reduced outside of the coils; wherein, when the coils are energized, the coils produce at the active electrode a time-varying oscillatory electric potential of a selected resonant frequency to establish between electrodes a time-varying oscillatory electric field in the vicinity of the beam path to accelerate ions. A general purpose resonant system based on the above-mentioned oppositely wound coil structure is also disclosed.Type: GrantFiled: February 17, 1995Date of Patent: April 2, 1996Assignee: Zimec Consulting, Inc.Inventor: Hilton F.

Patent number: 5483077Abstract: Deflection apparatus is shown for high perveance ion beams, operating at 20 Hz fundamental and substantially higher order harmonics, having a magnetic structure formed of laminations with thickness in range between 0.2 and 1 millimeter. Additionally, a compensator is shown with similar laminated structures with resonant excitation circuit, operating at 20 Hz or higher, in phase locked relationship with the frequency of the previously deflected beam. Furthermore, features are shown which have broader applicability to producing strong magnetic field in magnetic gap. Among the numerous important features shown are special laminated magnetic structures, including different sets of crosswise laminations in which the field in one lamination of one set is distributed into multiplicity of laminations of the other set of coil-form structures, field detection means and feedback control system, cooling plate attached in thermal contact with number of lamination layers.Type: GrantFiled: February 3, 1995Date of Patent: January 9, 1996Assignee: Nissin Electric Co., Ltd.Inventor: Hilton F.
