TSMC employees arrested for Apple iPhone chip leak

Suspects tied to internal data breach

The investigation began when TSMC’s internal systems detected irregular activity. Following an internal probe, the company reported its findings to Taiwan’s authorities. Between 25 July and 28 July, Taiwanese prosecutors searched homes and questioned several suspects. Of the six detained, two have been released on bail and one has been freed without charge.

New law targets tech espionage

This marks the first major investigation under Taiwan’s revised national security law, which now includes advanced technology as a critical asset. The law allows for prison sentences of up to 12 years and fines exceeding € 2.7 million for those found guilty of leaking key technology, such as semiconductor designs.

TSMC acts fast to contain damage

TSMC has dismissed the employees involved and launched legal proceedings. It stressed that the breach was identified early and that protective action has been taken. While the full extent of any data leakage remains under investigation, there are concerns about whether any information reached rival firms.

Global chip race adds pressure

The case emerges during a high-stakes battle for chip supremacy. TSMC and Samsung are investing more than € 27 billion each in annual capital expenditures, as companies like Meta and DeepSeek fuel demand for powerful AI processors. Meanwhile, China’s chipmakers still lag several generations behind, with Huawei stuck at 7nm production.

A crucial link in Apple’s supply chain

TSMC produces chips not only for Apple iPhones but also for Nvidia's AI accelerators. The security of its designs is vital to the global tech ecosystem. As 2nm chips enter mass production later this year, this case underlines the strategic and economic importance of chip IP protection.
