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.
