The United States is making it more difficult for chipmakers Samsung and SK Hynix to produce chips in China by revoking authorizations that allowed the companies to receive American semiconductor manufacturing equipment there, according to the Federal Register. The U.S. Commerce Department had given the companies exemptions to sweeping restrictions created in 2022 on the sale of U.S. semiconductor equipment to China. The companies will now need to obtain licenses to buy the equipment for China. The federal filing also included Intel among the companies who lost their authorization for China, but Intel sold its Dalian China unit in a deal that was finalized earlier this year. The Commerce Department and the three companies did not immediately respond to requests for comment. The licensing change will likely reduce sales to China by U.S. equipment makers KLA Corp, Lam Research and Applied Materials.
