Abstract:
A method for manufacturing a plasma processing system having a chamber, said chamber being configured for processing a substrate, comprising:providing a first sensor within said chamber, said first sensor being configured for monitoring a first parameter within said chamber during a testing step and for outputting first data, said testing step being part of a manufacturing process of said plasma processing system and being performed without striking a plasma within said chamber; and providing logic for analyzing said first data obtained from said sensor, said analyzing including performing a stepwise statistical analysis of said first data during said testing step in view of a reference baseline database; if said first data indicates a fault during said testing step, outputting a first signal responsive to said analyzing to enable a control module of said plasma processing system to terminate said testing step earlier than a scheduled termination time, said scheduled termination time representing a termination time that would have occurred if said first data had indicated no fault.
