TSMC, Apple's main chip manufacturer, is currently facing a serious security issue. Several former employees allegedly attempted to steal trade secrets related to the upcoming 2-nanometer chip process, which is central to the A20 chip expected to be used in the iPhone 18 series.

The iPhone 18 is scheduled to launch next year with one of the most advanced smartphone chips. Apple plans to use TSMC's 2nm process for the first time. But this very technology shift is now the target of an internal security scandal that could have significant repercussions not only for TSMC but also for Apple. The incident highlights the importance of technological advances and how sensitive information in this area has become.

Security vulnerability discovered at TSMC

According to a report by Nikkei Asia, TSMC has confirmed that former employees attempted to obtain classified information related to the development and production of the new 2-nanometer chip process. The incident was discovered due to an employee's "unusual access patterns" that were detected during a routine internal audit. In an official statement, TSMC referred to "unauthorized activities" that indicate a possible data leak. The individuals affected have been dismissed. The company has also initiated legal action. The Taiwanese prosecutor's office is already investigating. Since this involves key technology that is considered strategically important for the country, the potential impact is also being considered from a national security perspective.

Focus on the 2nm process for the iPhone 18

The 2-nanometer process in question represents the next major technological leap in chip manufacturing. TSMC is considered a global pioneer in this field. The technology is scheduled to be deployed on a large scale for the first time in 2026 – and Apple is expected to be the first customer to have access to it. Specifically, the new A20 chip for the iPhone 18 is planned to be based on this manufacturing technology. According to well-known Apple analyst Ming-Chi Kuo, the A20 chip will be installed not only in the Pro models, but in all iPhone 18 models.

No details about the stolen information

TSMC has not yet provided any specific details about which information is affected. However, according to the Nikkei Asia report, it is likely that the incident relates to general technical aspects of 2nm production—not directly to the A20 chip itself or specific iPhone 18 components. However, the information affected could still be sensitive enough to cause potential damage if it falls into the hands of competitors.

National importance of chip development

In Taiwan, the security of advanced technology is taken very seriously. The government views the semiconductor industry, in particular, as crucial to the country's economic and geopolitical stability. Accordingly, potential violations of secrecy and security regulations are strictly prosecuted. TSMC has announced that it will fully cooperate with the investigating authorities.

No impact on the iPhone 18 expected

Despite the incident, there is currently no indication that iPhone 18 development is specifically affected or could be delayed. Apple is expected to gain access to 2nm production as planned. However, whether the security incident will have long-term effects on the trust between Apple and TSMC remains to be seen.

iPhone 18 as a strategic milestone for Apple

The iPhone 18 series represents an important step for Apple toward even more powerful and energy-efficient smartphones. The planned A20 chip based on the 2nm process plays a central role in this. The attempt to steal classified information from TSMC demonstrates how critical this development step is – not only for the companies involved, but also in a geopolitical context. The investigations are ongoing, TSMC has taken action, and Apple should still be able to stick to its schedule for the iPhone 18. (Image: Shutterstock / Panuwatccn)
