Grand Process Technology Corporation, also known as GPTC, has denied reports that its key equipment technology flowed to China. The company is a supplier linked to TSMC’s advanced packaging work, including CoWoS, which is important for high-end AI chips and other advanced semiconductors.
The denial came after media reports claimed that confidential drawings and equipment-related information may have reached China. In a material information disclosure, GPTC said it has not found any evidence that critical technical secrets related to its equipment have flowed to China. The company also called the reports unfounded speculation.
GPTC says no key technology has been found in China, but the legal case keeps the issue under close watch
The situation is not simple because GPTC is denying the leak claim while also taking legal action. The company confirmed that it has filed a lawsuit over suspected trade secret infringement involving the person mentioned in the reports. That person is former general manager Huang Fu-Yuan. GPTC said the case is now under judicial investigation, so it cannot share more details publicly.
That makes the story sensitive. On one side, the company is trying to calm fears that important semiconductor equipment secrets have already left Taiwan. On the other side, the lawsuit shows GPTC believes there is enough concern to involve legal authorities.
| What is confirmed | What is still unclear |
|---|---|
| GPTC denies finding any key equipment technology leak to China | Whether investigators will find evidence later |
| The company has filed a lawsuit over suspected trade secret infringement | The exact details of the suspected infringement |
| The case is under judicial investigation | How much customer or supplier information may be involved |
| GPTC says it will cooperate with prosecutors and investigators | Whether the case will affect its supply chain role |
GPTC also said it places high importance on protecting intellectual property, trade secrets, and customer information. It added that all employees, no matter their rank, must follow company rules. This is likely meant to reassure investors and customers that internal controls are in place.
The timing matters because advanced semiconductor packaging has become a strategic area in the global chip race. CoWoS packaging is especially important because it helps combine powerful processors with high-bandwidth memory, which is needed for AI accelerators. Any claim involving possible leaks around this supply chain will naturally attract attention.
For Taiwan’s semiconductor industry, this is also part of a wider concern. Companies connected to TSMC hold valuable knowledge, not only in chipmaking itself but also in equipment, packaging, materials, and production processes. That makes trade secret protection a major issue.
Still, it is important not to treat the leak claim as proven. GPTC’s public position is clear: it has not found evidence that key equipment-related secrets went to China. The legal case will decide what happened, and until investigators reveal more, much of the public discussion remains speculation.
For now, GPTC is trying to do two things at once: defend its reputation and protect its technology through legal channels. That may not fully end the questions around the case, but it gives the clearest official position available so far.
