Supplier Fires Former Manager While Denying Tech Leak

GPTC, a main supplier for TSMC’s CoWoS packaging, says it has not shared any key technology with China. The company issued a statement through the stock market bulletin, confirming no leaks were found after rumors spread. At the same time, GPTC has taken legal action against its ex‑General Manager, Huang Fu‑Yuan. The lawsuit accuses him of possible trade‑secret violations. The case has moved to the judicial investigation phase, so GPTC cannot reveal further details. The firm insists it is fully cooperating with prosecutors and investigators. It reminds all employees to follow internal rules strictly.The allegation that GPTC’s advanced packaging tech went to China is mainly speculation. No evidence of confidential equipment or machinery being transferred has surfaced. Earlier, TSMC employees had been involved in leaks. China faces U. S. trade bans that restrict access to high‑end chip tools, such as those from ASML. The lawsuit against the former manager raises questions about internal security. GPTC’s move signals a warning to others who might try to misuse sensitive information.
