Publication number: 20070178678Abstract: Methods of ion implantation and ion sources used for the same are provided. The methods involve generating ions from a source feed gas that comprises multiple elements. For example, the source feed gas may comprise boron and at least two other elements (e.g., XaBbYc). The use of such source feed gases can lead to a number of advantages over certain conventional processes including enabling use of higher implant energies and beam currents when forming implanted regions having ultra-shallow junction depths. Also, in certain embodiments, the composition of the source feed gas may be selected to be thermally stable at relatively high temperatures (e.g., greater than 350° C.) which allows use of such gases in many conventional ion sources (e.g., indirectly heated cathode (IHC), Bernas) which generate such temperatures during use.Type: ApplicationFiled: January 28, 2006Publication date: August 2, 2007Applicant: Varian Semiconductor Equipment Associates, Inc.Inventors: Christopher Hatem, Jonathan England, Larry Sneddon, Russell Low, Anthony Renau, Alexander Perel, Kourosh Saadatmand

Publication number: 20070145298Abstract: Angle of incidence measurements along an axis of ion implantation are obtained by employing positive and negative slot structures. The positive slot structures have entrance openings, exit openings, and slot profiles there between that obtain portion(s) of an ion beam having a selected range of angles in a positive direction. The negative slot structures have entrance openings, exit openings, and slot profiles there between that obtain portion(s) of the ion beam having the selected range of angles in a negative direction. A first beam measurement mechanism measures beam current of the positive portion to obtain a positive angle beam current measurement. A second beam measurement mechanism measures beam current of the negative portion to obtain a negative angle beam current measurement. An analyzer component employs the positive angle beam current measurement and the negative angle beam current measurement to determine a measured angle of incidence.Type: ApplicationFiled: December 12, 2005Publication date: June 28, 2007Inventors: Brian Freer, Alexander Perel

Publication number: 20060071181Abstract: An ion beam implanter includes ion beam forming and directing apparatus and an implantation station where workpieces are implanted with ions from an ion beam. The beam travels along an evacuated path from an ion source to the implantation station. A flexible bellows couples the implantation station to the beam forming and directing apparatus permitting the implantation station to be pivoted with respect to the beam forming and directing apparatus and thereby change an implantation orientation of the workpieces with respect to the ion beam. A replaceable, flexible bellows liner is disposed within an interior region of the bellows to reduce the volume of implantation byproducts deposited on an interior surface of the bellows.Type: ApplicationFiled: October 1, 2004Publication date: April 6, 2006Inventors: Lyudmila Stone, Scott Barusso, Dale Stone, Alexander Perel

Publication number: 20050205807Abstract: The present invention is directed to in-situ detection of particles and other such features in an ion implantation system during implantation operations to avoid such additional monitoring tool steps otherwise expended before and/or after implantation, for example. One or more such systems are revealed for detecting scattered light from particles on one or more semiconductor wafers illuminated by a light source (e.g., laser beam). The system comprises an ion implanter having a laser for illumination of a spot on the wafer and a pair of detectors (e.g., PMT or photodiode) rotationally opposite from the ion implantation operations. A wafer transport holds a wafer or wafers for translational scanning under the fixed laser spot. A computer analyzes the intensity of the scattered light detected from the illuminated wafer (workpiece), and may also map the light detected to a unique position.Type: ApplicationFiled: March 18, 2004Publication date: September 22, 2005Inventors: Alexander Perel, Lyudmila Stone, William Loizides, Victor Benveniste
