    摘要: Embodiments described herein relate to a substrate support assembly. The substrate support assembly includes an ESC base assembly having a base channel disposed therein, a facility plate, the facility plate coupled to the ESC base assembly with a vacuum region therebetween, and a seal assembly. The seal assembly includes an upper flange coupled to the base channel of the ESC base assembly, the upper flange disposed in the facility plate, a lower flange coupled to the upper flange, the lower flange disposed in the facility plate, a gasket disposed between the upper flange and the lower flange, and an insulator tube coupled to the lower flange. A passage is connected to the base channel, the passage is defined by connected openings of the upper flange, the gasket, the lower flange, the insulator tube, and the base assembly.

    摘要: A method for calibrating an aligner station of an electronics processing system is provided. A calibration is retrieved, by a first robot arm of a transfer chamber, from a processing chamber connected to the transfer chamber. The calibration object has a target orientation in the processing chamber. The calibration is placed, by the first robot art, in a load lock connected to the transfer 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. A first characteristic error value associated with the processing chamber is determined based on the difference between the first orientation and the initial target orientation. 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.
