Kioxia, a major semiconductor manufacturer, announced that it has stopped producing storage semiconductors used in smartphones and other devices since late January due to a problem in a part of the manufacturing process at its factories in Mie and Iwate prefectures.
This means that there will be no impact on shipments for the time being as the product is in stock.
Kioxia manufactures storage semiconductors used in smartphones and other devices called "3D flash memory" at its factories in Yokkaichi City, Mie Prefecture and Kitakami City, Iwate Prefecture.
According to the announcement, defects were found one after another in the pre-shipment product inspections conducted at these two factories in late January.
As a result of the investigation, there was a problem that impurities were mixed in the parts used in a part of the manufacturing process, so the production of the main storage semiconductor was stopped.
According to the company, the product is in stock, so there will be no impact on shipping for the time being.
Since there is no problem with the production line itself, the company is aiming to procure parts for which impurities are found again and resume operations as soon as possible, but if procurement takes time, shipping may be affected. It is said that.
Kioxia says, "We will strive to reduce the impact on our customers."
