Japan’s Renesas Electronics today said the damage from a recent fire at its chip factory was greater than previously thought. The fire damaged not 11 but 17 installations used in semiconductor production.

Recall that a fire at a factory in Naka, Japan, broke out on March 19. As a result, the production lines used for serial production of microcircuits using semiconductor wafers with a diameter of 300 mm were damaged.

On March 21, Renesas management assured that the company would make every effort to resume production within a month. At that time, damage to 11 vehicles was confirmed, but subsequent inspections showed that combustion products damaged more equipment. According to the manufacturer, it is already trying to purchase replacement equipment – both new and used. In this, he is assisted by the Ministry of Economy, Trade, and Industry of Japan. An updated estimate of the amount of damage should be published tomorrow.

According to various estimates, Renesas occupies 20-30% of the world market for microcontrollers, including those used in cars. The fire will exacerbate the chip shortage, already forcing many automakers to suspend the assembly of cars.
