The only fab I am aware of that is still not running at all is the Freescale fab in Sendai. That fab was supposed to close at the end of this year, anyway. It was also the closest chip fab to the epicenter, something like 65 miles away, and was heavily damaged. The company announced a few months ago that that fab won't reopen and that it was transitioning manufacturing to other sites.
As for the other fabs (TI, Renesas) that are still ramping up, it takes some time from the cold start of a wafer fab (especially one where equipment has been repaired or replaced) to ramp up to full production. They are going through that now.
I wonder what the backlog is for those fabs still not operation at full capacity (or running at all)? I look forward to the fabs all being back online and Japan cleanup efforts completed. Thanks for the update!
This is good news for a lot of companies which depend on chips. Let's see that is pretty much most of the companies out there in the market. Now that they will go to pre-Faukashima days, this will hopefully bring down the prices.
