alt Hacker NewsIt didn’t happen, but the facilities team at the fab where I worked was seriously considering installing a flywheel to cover power bumps. What I don’t get about this story is how this actually happened. All our process gasses were out in a tank farm and we knew how much pressure we had. We would have stopped the line if there wasn’t enough to proceed. Were they separating air onsite or something?

Yes, Linde has an onsite plant and is building two more.
For some processes, stopping will botch the wafer. In the event of a gas shortage, do plants plan which lines to take down first, and which lines should complete a process step?

I was very impressed by the modest little fab I worked at having thousands of lead acid batteries for momentary takeover, and 8 five-megawatt locomotive engines for longer term redundancy. Apparently their steady state usage was 25MW, which allowed still having a hot spare and concurrent downtime for two of the locomotive generator units.
