  • Patent number: 12278134
    Abstract: A lift apparatus includes a lift assembly and a servo-control system. The lift assembly includes at least one pneumatic actuator including a movable member to provide a load to transfer a substrate between a support and a transfer plane. The lift assembly further includes at least one proportional pneumatic valve to control fluid flow between the actuator and a pressurized fluid supply or a vent, a plurality of pressure sensors each to measure pressure in a respective supply line to the actuator, and at least one position sensor to measure a position of the movable member. The servo-control system includes a controller to determine an output force based on a commanded force and an estimated force, generate a control signal based on the output force, and apply the control signal to the proportional valve to move the movable member.

  • Publication number: 20240021458
    Abstract: A calibration object is transferred from a processing chamber to an aligner station by one or more robot arms. The calibration object has a first processing chamber orientation in the processing chamber and a second orientation at the aligner station. A first characteristic error value associated with a transfer path between the processing chamber and the aligner is determined based on the first processing chamber orientation and the second orientation of the calibration object at the aligner station. In response to detecting an object at the aligner station to be transferred to the processing chamber along the transfer path, the object is aligned by the aligner station to be placed in the processing chamber according to a target processing chamber orientation based on a target aligner orientation as adjusted by the first characteristic error value determined for the transfer path between the processing chamber and the aligner station.

  • Patent number: 11823937
    Abstract: A calibration object is retrieved, by a first robot arm of a transfer chamber, from a processing chamber connected to the transfer chamber and placed in a load lock connected to the transfer chamber. The calibration object is retrieved from the load lock by a second robot arm of a factory interface connected to the load lock and placed at an aligner station housed in or connected to the factory interface. The calibration object has a first orientation at the aligner station. A difference is determined between the first orientation and an initial target orientation at the aligner station. A first characteristic error value associated with the processing chamber is determined based on the determined difference. The first characteristic error value is recorded in a storage medium. The aligner station is to use the first characteristic error value for alignment of objects to be placed in the processing chamber.

The calibration is retrieved from the load lock by a second robot arm of a factory interface connected to the load lock. The calibration object is placed, by the second robot arm, at an aligner station housed in or connected to the factory interface. The calibration object has a first orientation at the aligner station. A difference is determined between the first orientation at the aligner station and an initial target orientation at the aligner station. The initial target orientation at the aligner station is associated with the target orientation in the processing chamber.

  • Patent number: 10837119
    Abstract: In a processing system for electroplating semiconductor wafers and similar substrates, the contact ring of the electroplating processor is removed from the rotor of the processor and replaced with a previously deplated contact ring. This allows the contact ring to be deplated in ring service module of the system, while the processor continues to operate. Wafer throughput is improved. The contact ring may be attached to a chuck for moving the contact ring between the processors and the ring service module, with the chuck quickly attachable and releasable to the rotor.
