Method and system for estimating a state of an uninitialized advanced process controller by using segregated controller data

摘要

An APC controller is configured to operate on a segregated data structure during its normal operation and to establish a control state during an initializing event for a non-initialized manufacturing context on the basis of other initialized or non-initialized manufacturing contexts. Thus, the processing of pilot substrates may be reduced or the processing of the pilot substrates may be initiated on the basis of reliably established process parameters.
