  • Patent number: 11976369
    Abstract: In one aspect, a highly scalable diffusion-couple apparatus includes a transfer chamber configured to load a wafer into a process chamber. The process chamber is configured to receive the wafer substrate from the transfer chamber. The process chamber comprises a chamber for growth of a diffusion material on the wafer. A heatable bottom substrate disk includes a first heating mechanism. The heatable bottom substrate disk is fixed and heatable to a specified temperature. The wafer is placed on the heatable bottom substrate disk. A heatable top substrate disk comprising a second heating mechanism. The heatable top substrate disk is configured to move up and down along an x axis and an x prime axis to apply a mechanical pressure to the wafer on the heatable bottom substrate disk. While the heatable top substrate disk applies the mechanical pressure a chamber pressure is maintained at a specified low value.

    Abstract: Described herein is a method and apparatus for performing calibrations on robotic components. In one embodiment, a method for performing robotic calibrations includes moving the calibrating device across a target (e.g., a wafer chuck). Next, the method includes measuring distances between light spots from the sensors and a perimeter of the target using the sensors located on the calibrating device. Next, the method includes determining a displacement of the calibrating device relative to a center of the target. Then, the method includes determining a rotation angle of the calibrating device relative to a system of coordinates of the target. Next, the method includes calibrating a robot position of the robot based on the displacement and rotation angle of the calibrating device with respect to the target.

    Abstract: Described herein is a method and system for performing calibrations on robotic components. In one embodiment, a method for performing robotic calibrations includes manually calibrating a center of a robot blade aligned with respect to a target. The method further includes recording a first positional value of the center of the robot blade aligned with respect to a camera. The method further includes automatically determining a second positional value of the center of the robot blade aligned with respect to the camera.

  • Patent number: 7997851
    Abstract: A new apparatus for processing substrates is disclosed. A multi-level load lock chamber having four environmentally isolated chambers interfaces with a transfer chamber that has a robotic assembly. The robotic assembly has two arms that each can move horizontally as the robotic assembly rotates about its axis. The arms can reach into the isolated chambers of the load lock to receive substrates from the bottom isolated chambers, transport the substrates to process chambers, and then place the substrates in the upper chambers. The isolated chambers in the load lock chamber may have a pivotably attached lid that may be opened to access the inside of the isolated chambers.

  • Patent number: 7813832
    Abstract: A method and apparatus for positioning a substrate in a substrate processing chamber. The method includes placing the substrate on a substrate transfer blade, moving the substrate transfer blade to a first position located in a transfer chamber, and capturing at least one image that includes at least a portion of the substrate transfer blade and at least a portion of the substrate. The method also includes processing the image to determine a position of a predetermined portion of the substrate transfer blade and a position of predetermined portion of the substrate. The method further includes determining an offset between the position of the predetermined portion of the substrate transfer blade and the position of the predetermined portion of the substrate, and moving the substrate transfer blade to a second position located in the substrate processing chamber, wherein the second position is adjusted to account for the offset.
