Publication number: 20100312503Abstract: The invention relates to a method for determining the filling time for filling at least one material separator (1) provided with a fill level sensor (12) and a requirement sensor (11) in delivery systems made of at least one reservoir (4) with bulk material. In the beginning, with empty lines (3, 6) and an empty material separator (1), the bulk material is delivered out of the reservoir (4) from the time the requirement sensor (11) is triggered until the fill level sensor (12) is triggered, and said delivery time (TREF1) is measured and stored. If the requirement sensor (11) is triggered again, the delivery is carried out again until the fill level sensor (12) is triggered, and said delivery time (TREF2), which corresponds to the delivery time for filling the material separator (1), is measured and stored, whereby bulk material is present in the lines (3, 6) from the first delivery.Type: ApplicationFiled: December 16, 2008Publication date: December 9, 2010Applicant: WITTMANN KUNSTSTOFFGERAETE GMBHInventors: Erhard Fux, Michael Graf

Patent number: 7750320Abstract: A workpiece or semiconductor wafer is tilted as a ribbon beam is swept up and/or down the workpiece. In so doing, the implant angle or the angle of the ion beam relative to the workpiece remains substantially constant across the wafer. This allows devices to be formed substantially consistently on the wafer. Resolving plates move with the beam as the beam is scanned up and/or down. This allows desired ions to impinge on the wafer, but blocks undesirable contaminants.Type: GrantFiled: December 22, 2006Date of Patent: July 6, 2010Assignee: Axcelis Technologies, Inc.Inventors: Joseph Ferrara, Bo H. Vanderberg, Michael A. Graf

Publication number: 20100065761Abstract: A deflection component suitable for use in an ion implantation system comprises multiple electrodes that can be selectively biased to cause an ion beam passing therethrough to bend, deflect, focus, converge, diverge, accelerate, decelerate, and/or decontaminate. Since the electrodes can be selectively biased, and thus one or more of them can remain unbiased or off, the effective length of the beam path can be selectively adjusted as desired (e.g., based upon beam properties, such as energy, dose, species, etc.).Type: ApplicationFiled: September 17, 2008Publication date: March 18, 2010Applicant: Axcelis Technologies, Inc.Inventors: Michael A.
