Taiwan's government says it will work to ensure that the most advanced technology developed by Taiwan Semiconductor Manufacturing Co (TSMC) stays inside Taiwan, even as the chipmaker expands its footprint abroad.

According to the Taipei Times, the Cabinet made the statement after TSMC announced plans for an additional investment. Focus Taiwan similarly reported the Cabinet's position that TSMC's most advanced technology will remain in Taiwan.

TSMC is the world's largest contract chipmaker, producing the cutting-edge processors that power everything from smartphones to artificial-intelligence systems. Its most advanced manufacturing is often described as a cornerstone of Taiwan's economic and strategic importance — sometimes called the island's "silicon shield."

The Cabinet's assurance appears aimed at addressing concerns that expanding overseas production could gradually move Taiwan's crown-jewel capabilities beyond its borders. By pledging that the newest technology stays home, officials are signaling that overseas plants will not receive Taiwan's leading-edge processes, at least for now.

The sources do not specify the size of TSMC's new investment or which overseas locations are involved, and they do not detail how the government intends to enforce the commitment.

Why it matters: TSMC's most advanced chips underpin the global technology economy, so where that technology is made carries weight far beyond Taiwan — shaping national security, supply-chain resilience, and the balance of power in the semiconductor industry.
