  • Publication number: 20250230546
    Abstract: Various embodiments herein relate to apparatuses, systems, and methods for selective control of multi-station processing chamber components. In some embodiments, a method comprises: determining for a station of a plurality of stations, a number of deposition cycles to be performed; causing a first number of deposition cycles to be performed for each of the plurality of stations by causing a first plurality of control components associated with a first station and a second plurality of control components associated with a second station to be set to a first position; and responsive to determining that the first number of deposition cycles has been completed: causing at least one component of the first plurality of control components to be changed to a second position; and causing additional deposition cycles to be performed for the second station by causing the second plurality of control components to remain in the first position.
