TSMC’s key supplier has stated that no technology was leaked to China, but it also filed a lawsuit against its former General Manager.
TSMC Supplier Denies That Key Technology Was Leaked To China, But Files A Lawsuit Against Its Former General Manager
GPTC (Grand Process Technology Corporation), which is a key supplier for TSMC’s Advanced Packaging solutions such as CoWoS, has denied recent reports that key TSMC technology was leaked to China. In a recent press release, the company confirmed that no technology leaks were observed after recent rumors emerged.

However, at the same time, the company has filed a lawsuit against its former General Manager, Huang Fu-Yuan. The lawsuit claims that Huang was involved in “suspected” infringement of trade secrets. It is stated that the case has entered the Judicial Investigation stage, and as per the law, GPTC is not allowed to disclose any details regarding the case.
Advanced packaging process equipment manufacturer GPTC (3131) is a CoWoS supplier of TSMC (2330). Today (23), it was rumored that GPTC’s key technology was leaked to China. However, the company issued a press release through the stock market observation station, stating that no key technology has been found to have flowed to China.
The company has also said that it is fully cooperating with prosecutors and investigators of the case to protect the rights and interests of GPTC. The company put out a statement that all of its employees must abide by the company’s relevant regulations.
As per the initial reports, no transfer of key confidential technologies, such as equipment or machinery, has been found in relation to China. So most of the media chatter is based on speculation, but to start an investigation against its former GM does raise some questions. TSMC’s own employees have previously leaked key information in the past.
China has been hit with a series of trade bans by the US Government. The company has been trying to poach TSMC employees to gain access to their advanced fabrication and packaging expertise. More recently, China was banned from acquiring ASML’s bleeding-edge machinery and tools to advance its chip production.
