According to an embodiment of the present invention, a material processing
systeme (1) including a process tool (10) and a process performance
control system (100). The process performance control system (100)
includes a process performance controller (55) coupled to the process
tool (10), where the process performance controller (55) includes a
process performance prediction model (110), a process recipe correction
filter (120), a process controller (130), and process performance model
correction algorithm (150). The process performance prediction model
(110) is configured to receive tool data from a plurality of sensors
coupled to process tool (10) and to predict process performance data. The
process recipe correction filter (120) is coupled to the process
performance prediction model (110) and configured to receive predicted
process performance data and generate a process recipe correction for
run-to-run process control. The process controller (130) is coupled to
the process recipe correction filter (120) and is configured to update a
process recipe according to the process recipe correction.
