Remote optimization of purge flow rates in a container

Abstract

Optimizing purge flow parameters in a substrate container, includes streaming a purge working fluid into an interior of the substrate container, discharging the purge working fluid from the interior of the substrate container, and varying purge flow parameters of the purge working fluid for a predetermined period of time, detecting at least one environmental condition in the interior of the substrate container during the predetermined period of time, determining optimized purge flow parameters based on the varied purge flow parameters and the at least one detected environmental condition during the predetermined period of time, and adjusting the streaming and the discharging in accordance with the optimized purge flow parameters. The substrate container may include, for example, a front opening unified pod or a reticle pod.
