Although it was put out soon, Renesas has decided to temporarily stop the production of the 12 inch line, and there is no plan to resume production. < / P > < p > it's a real leak. Recently, many auto chip manufacturers have stopped production due to force majeure, which has strained the chip supply of major auto companies all over the world, and many of them have to stop production temporarily. The production of Renesas's 12 inch line will inevitably worsen the problem of car core shortage. < p > < p > at the beginning of this year, the earthquake in Japan shut down the chip factory of Renesas for nearly half a month. In the middle and late February, extreme cold weather occurred in Texas, resulting in the local water and power cut, resulting in the shutdown of two factories of NXP, the world's largest automobile chip factory, and the local production bases of Samsung Electronics and Infineon, the world's second largest chip factory. < / P > < p > according to the situation reported by Renesas, a fire broke out on the first floor of N3 floor of Naka factory in Ibaraki Prefecture at 2:47 a.m. local time on Friday. At 8:12, the fire was confirmed to have been put out and some supporting public facilities were damaged. Lisa is currently assessing the extent of the damage, but no one was injured. The 8-inch line of Naka factory located in N2 building was not affected by the fire. < / P > < p > < p > as of 11:00 p.m. on Friday, Renesas has not been able to confirm whether the ignition point affects the safety of the clean room (the main production site of chips), nor can it enter the clean room to determine the cause of the fire. At 9 a.m. on Saturday, the scene will be investigated by police and fire departments. Reza pointed out that once the cause and impact of the fire are determined, the company will issue an announcement. < / P > < p > Renesas did not disclose what kind of chips the damaged production line mainly produces, but half of its revenue comes from the automobile market, producing various chips used in automobiles, such as chips used in sensors and power plants. < / P > < p > with < a target = "_ blank" href=" https://news.163.com/news/search?keyword=%E5%8D%8A%E5%AF%BC%E4%BD%93 "> with the rapid development of semiconductor < / a > process technology, the chip line width has entered the nanometer level, and the corresponding products have higher and higher requirements for the production environment of semiconductor products. Therefore, the operation status of the clean room system of semiconductor purification project plays an important role in the quality and pass rate of silicon chip. The smoke and dust caused by the fire will cause great damage to the chip production environment.
