Taiwan considers TSMC export ban that would prevent manufacturing its newest chip nodes in U.S. — limit exports to two generations behind leading-edge nodes, could slow down U.S. expansion

Being concerned that TSMC’s expansion into the United States could dilute Taiwan’s semiconductor leadership, Taiwanese authorities are mulling setting a new export rule that would only let the world’s number-one foundry export technologies that are two generations behind its leading-edge production node, reports CNA. If this happens, this could slow down TSMC’s expansion in the U.S., as it currently relies on aggressive building of advanced fabs there.

The core of this new export policy is the…
