Samsung and SK Hynix test Chinese chip tools amid US restrictions

Samsung and SK Hynix are testing chip-making equipment from Chinese suppliers as a hedge against potential US restrictions, according to an exclusive report. The move comes as the US considers a ban on certain Chinese technology imports, which has already caused shares of Chinese optical module makers to slump. By diversifying their supply chains, the South Korean chip giants aim to reduce their dependence on US and other foreign equipment. This strategy reflects growing uncertainty in the global semiconductor industry amid escalating US-China trade tensions.
