A former Samsung engineer has been accused of providing detailed 10nm DRAM manufacturing process data to China's CXMT, allegedly accelerating China's advancement in memory technology. Handwritten notes containing over 600 manufacturing steps, including critical parameters like gas flow ratios and photoresist settings, were reportedly used to share sensitive information. The engineer faces charges under the Unfair Competition Prevention Act for sharing Samsung's sub-10nm DRAM process data with CXMT, potentially leading to significant financial losses for Samsung and South Korea. Despite heavy investments in digital security, handwritten notes remain a challenge to monitor, allowing for the exploitation of trade secrets. This incident highlights the ongoing risks of industrial espionage and the importance of safeguarding sensitive technological information.

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.
