Renesas says it will take at least a month to restart fire-damaged chip line
TOKYO (Reuters) - Japan’s Renesas Electronics, a key automotive semiconductor supplier, said on Sunday that production at a fire-damaged plant will take at least a month to restart, potentially worsening a chip shortage that is disrupting car production.
About two-thirds of production on the advanced 300mm wafer line affected by Friday’s fire is automotive chips, CEO Hidetoshi Shibata told an online briefing.
“It comes at a time when there isn’t excess production capacity,” he said.
Carmakers are already struggling with a global chip shortage caused by a COVID-19-driven boom in consumer electronics and an unexpected strong rebound in auto sales. Makers such as Ford Motor Co , Honda Motor Co and Nissan Motor Co have had to trim production plans as a result.
Carmakers will start to feel a supply pinch in about a month, according to Renesas.
A Toyota Motor Corp spokeswoman said the world’s largest carmaker is currently assessing the situation.
The fire at the Naka chip plant in northeast Japan destroyed 11 machines, or 2% of the manufacturing equipment, and sent smoke billowing through the clean room where even small particles of dust can damage wafers during the sensitive fabrication process.
Renesas may not be able to replace all the destroyed equipment within a month, Shibata said, meaning that a return to full production could take longer.
The latest disruption at the Naka plants comes after production stopped for a few days last month after an earthquake cut power and back up generators failed to start.
In 2011, Renesas had to close the facility for three months following the deadly earthquake that devastated Japan’s northeast coast.
