Taiwanese chipmaker TSMC, a crucial partner of Apple, has dismissed several employees suspected of attempting to acquire confidential information related to its 2 nm manufacturing process, which is intended for the future A20 chips of the iPhone 18. Legal and criminal proceedings are underway.

Critical Secrets of the 2 nm Etching Process
TSMC, the global leader in semiconductor manufacturing, has confirmed the detection of unauthorized activities
that led to the discovery of a potential industrial secret leak concerning its 2 nanometer etching process. This advanced method is central to the upcoming SoC A20 expected to power the entire iPhone 18 lineup slated for release in 2026.
As reported by Nikkei Asia, several former employees are suspected of trying to access confidential data on the development and production of this cutting-edge technology before leaving the company.
Anomalies Detected through Internal Monitoring
It was during routine checks that TSMC reportedly identified unusual access patterns within its internal systems, enabling the identification of the involved employees. These individuals were immediately terminated, and legal proceedings were initiated by the company.
The Taiwanese judiciary is taking the matter very seriously. Prosecutors have launched a criminal investigation, even suggesting potential implications for national security. Indeed, the Taipei government considers the protection of sensitive technologies developed domestically strategic in competing internationally.
Stakes Extend Beyond Apple
Currently, no details have emerged about the potentially compromised information. It appears that the alleged theft involves the entire 2 nm etching process, not specifically Apple’s A20 chip. However, the special relationship between Apple and TSMC, which typically grants early access to the most advanced etching nodes, naturally puts Cupertino in the spotlight.
Analyst Ming-Chi Kuo recently suggested that all iPhone 18 models—not just the Pro versions—might feature this new generation 2 nm chip, heralding significant improvements in performance and energy efficiency.
TSMC states it is fully cooperating with authorities and is committed to ensuring the individuals involved are prosecuted. Amid rising tensions over technological sovereignty and industrial espionage, this incident highlights the growing geopolitical stakes associated with the latest generation of semiconductors.
