Twelve years ago I was new to the industry and naive. I wondered why we couldn't have a real-time "war room" where we could punch up any of our systems around the world and get that real time information. Not beating the issue to death: One of the basics in troubleshooting would be collecting real time data; for example a "glitch" in RF tuning network might correlate to an intermittant problem Intermittant problems ARE THE WORST because everything could be ok for 25 or 50 or 100 wafers and suddenly BOOM . There is NO other way to troubleshoot this kind of problem without realtime collecting all parameters for 25, 50 or 100 wafers and than hopefully find out what was different on the wafer that "crashed". So collecting real time data was a S.O.P. Of course you need software to diggest the data; even the AutoEtch 20 years ago would have programable "tolerances" - for example gasflow or RF would not stabilize within a certain time period the tool would alarm and the abort.
