  • Publication number: 20150206701
    Abstract: An adjustable mass-resolving slit assembly includes an aperture portion and an actuation portion. The aperture portion includes first and second shield members that define an aperture therebetween for receiving an ion beam during semiconductor processing operations. The actuation portion is coupled to the aperture portion and selectively and independently adjusts the position of the first and second shield members along first and second non-parallel axes. Adjusting the position of the first and second shield members along the first axis adjusts a width of the aperture. Adjusting the position of the first and second shield members along the second axis adjusts a region of the first and second shield members impinged by the ion beam. Methods for using the adjustable mass-resolving slit assembly are also disclosed.

  • Publication number: 20150125240
    Abstract: An apparatus for dynamically adjusting the pitch between substrates in a substrate stack comprises first and second lift portions. The first lift portion supports a first group of the plurality of substrates, and the second lift portion supports a second group of the plurality of substrates. The first and second lift portions are operable to move the first and second groups of substrates in a first direction independently from each other. This independent movement enables the pitch, or spacing, between adjacent substrates to be dynamically adjusted so that an end effector of a robot can be positioned between such adjacent substrates to pick one of the substrates without inadvertently engaging another substrate that is not being picked. Other embodiments are disclosed.

  • Publication number: 20140271050
    Abstract: A wafer handling system may include upper and lower linked robot arms that may move a wafer along a nonlinear trajectory between chambers of a semiconductor processing system. These features may result in a smaller footprint in which the semiconductor processing system may operate, smaller transfer chambers, smaller openings in process chambers, and smaller slit valves, while maintaining high wafer throughput. In some embodiments, simultaneous fast wafer swaps between two separate chambers, such as load locks and ALD (atomic layer deposition) carousels, may be provided. Methods of wafer handling are also provided, as are other aspects.

  • Publication number: 20140225007
    Abstract: A system for loading workpieces into a process chamber for processing in a matrix configuration includes a conveyor configured to transport multiple workpieces in a linear fashion. A workpiece hotel is configured to receive the multiple workpieces from the conveyor. The workpiece hotel comprises a matrix of cells arranged in N columns and M floors. A pick blade is configured to insert into the hotel and retract from the hotel in order to unload a plurality of substrates from a first floor into a single row of the pick blade, and to repeat the unloading operation to form a matrix comprising a plurality of rows of substrates disposed on the pick blade. In one example, the workpiece hotel has a staggered configuration that provides individual accessibility of each hotel cell.

  • Publication number: 20140165906
    Abstract: An ion implant apparatus configured to measure the temperature or monitor the degradation of components in the apparatus is provided. The ion implant apparatus may include a platen configured to move in a first direction, a mask frame to hold one or more masks disposed on the platen, a first optical sensor configured to project an optical beam to a second optical sensor, and a measurement bar disposed on the mask frame, the measurement bar raised above the surface of the mask frame to interrupt the optical beam when the platen moves in the first direction.
