  • Publication number: 20240051144
    Abstract: One or more first signals are obtained. The first signals indicate a current shape of an object placed on an end effector. The one or more first signals are compared to one or more second signals that each indicate a predefined shape for a process component on the end effector. A determination is made of whether a current placement of the object on the end effector satisfies a target placement criterion based on the comparison.

  • Patent number: 11813757
    Abstract: A method for finding a center of a process kit and/or a process kit ring is provided. An object placed on an end effector is moved past a sensor of a manufacturing system. A first signal indicating a current shape of object is received from the sensor of the manufacturing system. A determination is made whether the first signal corresponds to a second signal indicating a predefined shape for a process kit and/or a process kit carrier. In response to a determination that the first signal corresponds to the second signal, a coordinate correspondence is determined between coordinates of a center of the object and coordinates of a center of the end effector. The determined coordinate correspondence indicates whether a current placement of the object on the end effector satisfies a target placement criterion.

  • Publication number: 20210172728
    Abstract: Implementations disclosed describe an inspection device capable of being transferred by a robot blade into a processing chamber of a manufacturing machine, the inspection device comprising an optical sensor to detect light reflected from a target located within the processing chamber, wherein the optical sensor is to output, to a processing device, a signal representative of a state of a region of a surface of the target.

  • Patent number: 11031262
    Abstract: Implementations disclosed herein describe a bevel etch apparatus within a loadlock bevel etch chamber and methods of using the same. The bevel etch apparatus has a mask assembly within the loadlock bevel etch chamber. During an etch process, the mask assembly delivers a gas flow to control bevel etch without the use of a shadow frame. As such, the edge exclusion at the bevel edge can be reduced, thus increasing product yield.

  • Patent number: 10916451
    Abstract: An electronic device manufacturing system includes a motion control system for calibrating a gap between surfaces of process chamber or loadlock components by moving those component surfaces into direct contact with each other. The component surfaces may include a surface of a substrate and/or a substrate support and a surface of process delivery apparatus, which may be, e.g., a pattern mask and/or a plasma or gas distribution assembly. The motion control system may include a motion controller, a software program executable by the motion controller, a network, one or more actuator drivers, a software program executable by the one or more actuator drivers, one or more actuators, and one or more feedback devices. Methods of calibrating a gap via direct contact of process chamber or loadlock component surfaces are also provided, as are other aspects.
