  • Publication number: 20240145270
    Abstract: A system for transferring semiconductor workpieces from a load lock to an orientation station and on to a platen is disclosed. The system comprises two load locks, two robots, and one orientation station. Each robot is associated with a respective load lock and follows a fixed sequence. The robot returns a processed workpiece to the load lock and also removes an unprocessed workpiece. The robot then moved to the orientation station, where it removes an aligned workpiece from the orientation station and deposits the unprocessed workpiece on the orientation station. Next, the robot moves to the platen, where it removes a processed workpiece and deposits the aligned workpiece. The robot then returns to the load lock and repeats this sequence.

  • Publication number: 20230187166
    Abstract: A system comprising a spinning disk is disclosed. The system comprises a semiconductor processing system, such as a high energy implantation system. The semiconductor processing system produces a spot ion beam, which is directed to a plurality of workpieces, which are disposed on the spinning disk. The spinning disk comprises a rotating central hub with a plurality of platens. The plurality of platens may extend outward from the central hub and workpieces are electrostatically clamped to the platens. The plurality of platens may also be capable of rotation. The central hub also controls the rotation of each of the platens about an axis orthogonal to the rotation axis of the central hub. In this way, variable angle implants may be performed. Additionally, this allows the workpieces to be mounted while in a horizontal orientation.

  • Patent number: 10443934
    Abstract: A system for heating substrates while being transported between the load lock and the platen is disclosed. The system comprises an array of light emitting diodes (LEDs) disposed above the alignment station. The LEDs may be GaN or GaP LEDs, which emit light at a wavelength which is readily absorbed by silicon, thus efficiently and quickly heating the substrate. The LEDs may be arranged so that the rotation of the substrate during alignment results in a uniform temperature profile of the substrate. Further, heating during alignment may also increase throughput and eliminate preheating stations that are currently associated with the processing chamber.
