Wow-sounds like the facilities guys at Yokkaichi have some 'splainin' to do! Modern fabs have protection against power sags like this, redundant power feeds, and generators that snap on quickly enough for long power down periods. They "should" protect against this. I'm not sure if Mie Prefecture is on the 50 or 60 hz side of Japan, but if it's 60Hz, it would be only a voltage drop for 4 cycles (rounding 4/60) for a 0.07s voltage drop. I worked at a fab that had voltage dropouts like this maybe 5-10 times a year. You'd know it was happening when the lighting dimmed slightly (office area was not power conditioned). Our critical tools were on an internal UPS circuit. Often the ones that weren't would power down, and we'd have to bring those tools back up. We rarely lost product because of this. This must have taken down some key tools, I can't see this taking out the air and water systems, unless it took down some high voltage fab systems. At that point recovery would take quite a while. 20% indicates a major FUBAR.
