TAIPEI: Taiwanese chipmaker TSMC said on Monday it is communicating with Washington about its “guidance” for a law designed to boost US semiconductor manufacturing that has sparked concerns about subsidy criteria.

Conditions for subsidies include sharing excess profit with the US government, and industry sources have said the application process itself could expose confidential corporate strategy.

“We can confirm that we are communicating with the US government about the CHIPS ACT guidance,” TSMC, the world’s leading contract chipmaker, said in a short emailed statement.

South Korean President Yoon Suk Yeol also said last month that the criteria are worrying companies like Samsung Electronics Co Ltd and SK Hynix Inc.

Taiwan Economy Minister Wang Mei-hua told reporters on Monday that TSMC was specifically talking to the United States about the details of the subsidies.

“The Taiwan government and industry have a very close understanding (of what is going on) and hope that the details of the relevant subsidy legislation will not affect industrial cooperation between the two sides and costs for industry-related construction,” she said.

The US Commerce Department told Reuters that it will protect confidential business information and expects “upside sharing” will only happen in instances where projects significantly exceed projected cash flow.

Taiwan Semiconductor Manufacturing Co Ltd (TSMC) is investing $40 billion in a new plant in the western US state of Arizona, supporting Washington’s plans for more chip-making at home.

Details of expected subsidies for the plant have not been disclosed. The subsidies would come from a $52 billion pool of research and manufacturing funds earmarked under the CHIPS Act.
