WASHINGTON (REUTERS) - Democratic lawmakers on Tuesday (May 19) urged the Trump administration to answer "serious questions" about Taiwan Semiconductor Manufacturing Co Ltd's (TSMC) plans to build a US-based US$12 billion (S$17 billion) plant, flagging national security concerns and potentially undisclosed subsidies.
TSMC, the world's biggest contract chipmaker and supplier to US tech giants such as Apple Inc, announced the project last week, in a move trumpeted by Commerce Secretary Wilbur Ross as signalling a "renaissance in American manufacturing" fueled by President Donald Trump.
In a letter addressed Tuesday to Mr Ross and Defence Secretary Mark Esper, top Senate Democrat Chuck Schumer and two colleagues said they "strongly support" efforts by the administration to"on-shore" semiconductor plants in the United States.
But Mr Schumer, along with Mr Patrick Leahy and Mr Jack Reed, urged more transparency and asked the government to consider"companies that already have built a significant presence in the US", citing Micron, GlobalFoundries and Cree.
"We have serious questions as to how this project takes into consideration national security requirements and how it aligns with a broader strategy for building a diverse US semiconductor manufacturing supply chain," the men wrote of the TSMC plan.
"We ask that you cease any such negotiations or discussions until you have briefed the relevant authorisation and appropriations committees with your plans, including any commitments you have made to funding, tax breaks, licensures, or other incentives," they added.
Commerce, the Pentagon and TSMC did not immediately respond to requests for comment.
TSMC, which is a key supplier to Chinese telecoms giant Huawei, has found itself in the cross fire of a global technology battle between Washington and Beijing.
The Taiwanese firm will likely be hit by a new US rule aimed at curbing global chip supplies to Huawei, which it placed on a black list last year on national security grounds. But the US government also negotiated with TSMC for years to open a US-based plant, Reuters reported, as it seeks to bring more chip manufacturing onshore.
