Method, system, and non-transitory computer readable storage medium of input / output (IO) handling during update process for manufacturing system controller

Abstract

Methods and systems for input / output (IO) handling during an update process for a manufacturing system controller are provided. First notifications are transmitted by an IO driver of a system controller between components of a process chamber and a substrate process IO handler of the system controller. The substrate process IO handler executes substrate process control instructions corresponding to a process recipe. The first notifications correspond to operations associated with substrate process control instructions. A determination is made that substrate process control instructions are to be updated. A detection is made that the substrate process is terminated. Second notifications are transmitted between the components of the process chamber and a system IO handler. The system update IO handler executes system update control instructions including commands configured to cause the components of the process chamber to maintain an environment of the process chamber at a target condition while the substrate process control instructions are updated.
