TSMC has been reported to have a leak of its 2nm process trade secrets, prompting judicial investigators to launch an investigation under suspicion of violating the National Security Act. A senior government official stated that the National Science and Technology Council (NSTC) has already begun enlisting experts to determine whether the information leaked by a TSMC engineer involves serious national core critical technologies. However, the official also noted that TSMC’s key production parameters and trade secrets are stored in segmented parts; if the leaker only obtained a portion, other companies would be unable to use it even if acquired.

VisEra Technologies, a TSMC-affiliated optical component supplier, anticipates third-quarter growth driven by rising demand for CMOS image sensors (CIS), as high-end smartphone camera adoption expands and automotive sensing features reach lower-tier vehicle models. Meanwhile, shipments of micro-optics elements (MOE) are seeing short-term weakness due to dispersed customer product lines, with recovery expected no earlier than 2026.

Everlight Chemical posted NT$6.216 billion (approx. US$208 million) in consolidated revenue for July 2025, a decrease of NT$72.27 million (approx. US$2.4 million) or 10.4% year-on-year from the NT$6.939 billion (approx. US$232 million) in July 2024.
