The company’s Naka factory in Ibaraki prefecture, northwest of Tokyo, was damaged during the magnitude 9.0 earthquake on March 11. The company needs time to filter particles from the air to restore the “clean room” environment in which chips are made. The disruption has pushed Renesas to move production of some chips to its other factories in Japan. In some cases, it has shifted production to other chip makers until the factory is up and running again. About 2,000 workers have been called in from across the company to aid in the recovery work.”]
