SK hynix is investing $3.9 billion in building its first U.S. packaging plant for HBM in Indiana, aiming to address the bottleneck in high-end GPU production and meet the increasing demand for AI silicon. The facility, partially funded by CHIPS Act grants, will produce turnkey HBM modules for AI accelerators by 2028, challenging TSMC's dominance in HBM packaging. By vertically integrating its supply chain, SK hynix aims to offer a complete solution to customers, potentially reshaping the AI supply chain landscape. The move aligns with the U.S. government's focus on advanced packaging as a national security priority, with SK hynix poised to become a key player in the evolving AI supply chain.

US stops exports of tools to China’s number two chip maker — Hua Hong and Huali Microelectronics reportedly on the cusp of starting a 7-nm fab in Shanghai

The US Department of Commerce has instructed toolmakers to cease exports to Hua Hong, China's second-largest chipmaker, which is gearing up to establish a 7-nm production line in Shanghai. This move is part of the US strategy to impede China's semiconductor self-sufficiency efforts. Companies like TSMC and ASML have also faced restrictions in providing advanced services to Chinese tech firms. The ban on exports could strain US-China relations, impacting both Chinese companies' progress and potential losses for American toolmakers.
