Former Samsung engineer accused of giving 10nm DRAM data to China's CXMT, handwritten notes detailed over 600 process steps — gas flow ratios, photoresist settings and more critical stages detailed

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.
