CXMT ex-CEO allegedly pressured Korean engineers for Samsung DRAM technology

The testimony highlights how direct pressure from CXMT's former CEO, David Wang, allegedly aimed to secure Samsung's advanced 18-nanometer DRAM technology. This alleged pressure included threats and a code name, "Yellow Mountain," for Samsung Electronics, indicating a deliberate and covert effort to obtain proprietary information. The 18-nanometer process was a significant breakthrough for Samsung in 2016, representing substantial investment and miniaturization achievement.

The former Samsung employee, surnamed Jeon, who provided the testimony, was subsequently indicted and sentenced for illegally leaking and using the technology. Jeon's account suggests that CXMT's pursuit of this technology was driven by intense pressure from the Chinese government, which allegedly conditioned investment in CXMT on the company's ability to achieve 18-nanometer production. This implies that CXMT may not have planned to independently develop the technology.

The alleged demands for specific manufacturing details, such as the 600-step process recipe plan, underscore the value placed on detailed, proven production methodologies in advanced semiconductor manufacturing. The prosecutor's view, that the CEO's threats indicated knowledge of illegal activity, points to the perceived sensitivity and proprietary nature of the information sought. This incident reveals the high stakes and competitive pressures within the global semiconductor industry, particularly concerning advanced memory technology.
