Renesas today announced a final update on the impact of the earthquake that hit the coast of Fukushima Prefecture and the surrounding areas on March 16 at 11:36 p.m. JST on Renesas Group operation. 

Renesas operates three factories close to the epicenter: Naka Factory (Hitachinaka, Ibaraki Prefecture), Takasaki Factory (Takasaki, Gunma Prefecture) and Yonezawa Factory (Yonezawa, Yamagata Prefecture). Production of Takasaki and Yonezawa factories has already fully resumed, and the status of Naka Factory is as follows:

  • Naka Factory, Renesas Semiconductor Manufacturing Co., Ltd.
    • We have reached full pre-earthquake production capacity (wafer input base) on March 26 JST, as we had previously announced.
    • Some damage was made to the work-in-process at the time of the earthquake. Losses due to ruined work-in-process and reduced production account for approximately 2 weeks’ worth of production for the 200-mm (8-inch) wafer fabrication line, and approximately 3 weeks for the 300-mm (12-inch) line. We are moving forward to recover these shortfalls.
