Patent number: 12041203Abstract: Various examples are directed to systems and methods for detecting potentially fraudulent voice calls to a financial services institution. A computing system may receive an indication of a voice call placed by a voice caller to an operator. The computing system may generate a network address indicator describing a network location. The network address indicator may be provided to the voice caller. The computing system may receive an indication of a financial services account indicated by the voice caller. The computing system may also receive an indication of an access to the network location by a remote device. The computing system may determine, using the indication of the access to the network location, a first location associated with the remote device and determine that the first location does not match a second location associated with the financial services account. The computing system may generate an alert indicating that the voice call is potentially fraudulent.Type: GrantFiled: April 20, 2023Date of Patent: July 16, 2024Assignee: Wells Fargo Bank, N.A.Inventors: John Talbert Jackson, Gene C. Baker, Jr., Jon T. Graff, Chad Otto Breunig, Kevin W. Bell, Darrell Lee Suen

Patent number: 10825653Abstract: A method for improving the ion beam quality in an ion implanter is disclosed. In some ion implantation systems, contaminants from the ion source are extracted with the desired ions, introducing contaminants to the workpiece. These contaminants may be impurities in the ion source chamber. This problem is exacerbated when mass analysis of the extracted ion beam is not performed, and is further exaggerated when the desired feedgas includes a halogen. The introduction of a diluent gas in the ion chamber may reduce the deleterious effects of the halogen on the inner surfaces of the chamber, reducing contaminants in the extracted ion beam. In some embodiments, the diluent gas may be germane or silane.Type: GrantFiled: September 21, 2018Date of Patent: November 3, 2020Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: John W. Graff, Bon-Woong Koo, John A. Frontiero, Nicholas P. T. Bateman, Timothy J. Miller, Vikram M. Bholse

Patent number: 9034743Abstract: A method of processing a workpiece is disclosed, where the ion chamber is first coated with the desired dopant species and another species. Following this conditioning process, a feedgas, which comprises fluorine and the desired dopant, is introduced to the chamber and ionized. Ions are then extracted from the chamber and accelerated toward the workpiece, where they are implanted without being first mass analyzed. The other species used during the conditioning process may be a Group 3, 4 or 5 element. The desired dopant species may be boron.Type: GrantFiled: November 26, 2013Date of Patent: May 19, 2015Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: Peter F.

Patent number: 8895325Abstract: A system and method are disclosed for aligning substrates during successive process steps, such as ion implantation steps, is disclosed. Implanted regions are created on a substrate. After implantation, an image is obtained of the implanted regions, and a fiducial is provided on the substrate in known relation to at least one of the implanted regions. A thermal anneal process is performed on the substrate such that the implanted regions are no longer visible but the fiducial remains visible. The position of the fiducial may be used in downstream process steps to properly align pattern masks over the implanted regions. The fiducial also may be applied to the substrate before any ion implanting of the substrate is performed. The position of the fiducial with respect to an edge or a corner of the substrate may be used for aligning during downstream process steps. Other embodiments are described and claimed.Type: GrantFiled: April 27, 2012Date of Patent: November 25, 2014Assignee: Varian Semiconductor Equipment Associates, Inc.Inventors: John W. Graff, Benjamin B. Riordon, Nicholas P. T. Bateman

Publication number: 20140224310Abstract: One method of implanting a workpiece involves implanting the workpiece with an n-type dopant in a first region with center and a periphery. The workpiece also is implanted with a p-type dopant in a second region complementary to the first region. This second region also has a center and a periphery. The periphery of the first region and the periphery of the second region at least partially overlap. A dose at the periphery of the first region or second region is less than a dose at the center of the first region or second region. The region of overlap may function as a junction where charge carriers cannot pass.Type: ApplicationFiled: April 15, 2014Publication date: August 14, 2014Inventors: Nicholas P.T. Bateman, Peter F.
