Supplier Fires Former Manager While Denying Tech Leak

GPTC, a major supplier for TSMC’s CoWoS packaging, has denied any transfer of key technology to China. In a statement released through the stock market bulletin, the company confirmed that no leaks were discovered following widespread rumors.

Legal Action Against Former General Manager

The firm has initiated a lawsuit against its ex‑General Manager, Huang Fu‑Yuan, alleging possible trade‑secret violations. The case has progressed to the judicial investigation phase, preventing GPTC from disclosing further details.

“We are fully cooperating with prosecutors and investigators,” the company added, urging all employees to adhere strictly to internal rules.

The Speculation vs. Reality

Claims that GPTC’s advanced packaging technology reached China remain speculative, with no evidence of confidential equipment or machinery transfers surfacing. Earlier incidents involving TSMC employees had led to leaks, but China’s U.S. trade bans restrict access to high‑end chip tools such as those from ASML.

Implications for Internal Security

The lawsuit against the former manager underscores concerns about internal security. GPTC’s decisive action serves as a warning to anyone considering misusing sensitive information.
