Abstract:
1. An apparatus for depositing material on substrates, comprising: a rotary actuator having a rotational axis; a first substrate support and a second substrate support each coupled to the rotary actuator; a first conveyor positioned to transfer the substrates to the first substrate support when the rotary actuator is angularly positioned in a first orientation; a second conveyor positioned to receive the substrates from the first substrate support when the rotary actuator is angularly positioned in the first orientation; a third conveyor positioned to transfer the substrates to the second substrate support when the rotary actuator is angularly positioned in the first orientation; and a fourth conveyor positioned to receive the substrates from the second substrate support when the rotary actuator is angularly positioned in the first orientation, wherein each of the conveyors comprises an upper section supporting at least one belt and configured to extend and retract with respect to a lower section of the conveyor.
