U.S. President Donald Trump said Friday his administration will unveil tariffs on semiconductor imports as early as next week.

Officials in Taiwan and South Korea say they don't expect Trump's 100% tariff on foreign chips to affect TSMC or Samsung, likely due to their factory investments in the US.

President Donald Trump stunned markets Wednesday by announcing 100% tariffs on imported semiconductor chips — but major chip stocks rallied. Taiwanese chip giant TSMC's stock closed 4.9% higher. In South Korea, Samsung Electronics ended 2.5% higher while SK Hynix reversed losses of over 3% in early trade to close 1.4% up.
