  • Patent number: 11145496
    Abstract: A fastening system for attaching two components with a spring force is disclosed. The fastening system utilizes O-rings to provide the spring force, eliminating the need for any metal components. The O-ring may be disposed in an O-ring holder that has a plurality of spokes. When compressed, indentations are created in the O-ring by the spokes. The number of spokes and their size and shape determine the spring force of the fastening system. In another embodiment, vertically oriented O-rings are utilized. The fastening system may be used to fasten various components of an ion source.

  • Patent number: 10062544
    Abstract: An apparatus for improving the uniformity of an ion beam is disclosed. The apparatus includes a heating element to heat an edge of the suppression electrode that is located furthest from the suppression aperture. In operation, the edge of the suppression electrode nearest to the suppression electrode may be heated by the ion beam. This heat may cause the suppression electrode to distort, affecting the uniformity of the ion beam. By heating the distal edge of the suppression electrode, the thermal distortion of the suppression electrode can be controlled. In other embodiments, the distal edge of the suppression electrode is heated to create a more uniform ion beam. By monitoring the uniformity of the ion beam downstream from the suppression electrode, such as by use of a beam uniformity profiler, a controller can adjust the heat applied to the distal edge to achieve the desired ion beam uniformity.

  • Patent number: 9484183
    Abstract: An ion implantation apparatus including an enclosure defining a process chamber, a carriage slidably mounted on a shaft within the process chamber and coupled to a drive mechanism adapted to selectively move the carriage along the shaft. A platen assembly can be coupled to the carriage, and a linkage conduit can extend between a side wall of the enclosure and the carriage. The linkage conduit can include a plurality of pivotably interconnected linkage members that define a contiguous internal volume that is sealed from the process chamber. The contiguous volume can be held at a desired vacuum pressure separate from the vacuum environment of the process chamber.

  • Patent number: 9337076
    Abstract: A workpiece adjustment assembly is disclosed. The assembly can include a shaft, a spherical bearing, and a wafer support. A spherical housing receives the spherical bearing and allows the bearing to rotate therein. The housing and bearing may form an air bearing. A seal may be formed in the housing to prevent gas from the air bearing and the ambient atmosphere from migrating to a process chamber side of the housing. A set of spherical air pads may be positioned on an ambient side of the bearing to press the bearing against the housing when the process chamber is not under vacuum conditions. The seal can include a set of differentially pumped grooves. The spherical bearing enables the wafer manipulation end, and a wafer attached thereto, to be moved with four degrees of freedom. The arrangement facilitates isocentric scanning of a workpiece. Methods for using the assembly are also disclosed.
