Got low DC bias alarms during seasoning and actual run- was able to continue the process without any problems. Carefully checked for signs of arcing but didn't find anything. I was running process 3 - etching SiO2 on wafers with very high resist coverage. Pumped down to 0.2mT base pressure (instead of standard 0.8mT.)
