TSMC's $20 Billion U.S. Expansion Approved by Taiwan Authorities
Miles Bennett
Taiwan's investment review body approved TSMC's $20 billion capital injection into its Arizona subsidiary for wafer and packaging plants — the sixth such approval, bringing cumulative authorized U.S. investment to $44 billion.
What exactly will the $20 billion fund?
The capital goes to TSMC Arizona for a 12-inch wafer fab and an advanced packaging plant.
This is the sixth approval from Taiwan's Investment Commission. Cumulative authorized investment rises from $24 billion to $44 billion.
This means → TSMC's U.S. capacity build has moved well past a single pilot fab into a sustained, near-doubling expansion.
Is Trump's "50% market share" target realistic?
Trump recently said Taiwan would double the scale of fabs under construction and that U.S. chip market share would reach 50% before his term ends.
In plain terms = the vast majority of advanced chip manufacturing is in Asia today. Closing a gap that large in a few years is an enormous undertaking.
Whether TSMC Arizona can hit production timelines and yield targets is the first real proof point for that goal.
Which other Taiwanese firms were approved to invest in the U.S.?
Quanta Computer (廣達電腦): $600 million into a U.S. subsidiary for PC and peripheral assembly.
Lite-On Technology (光寶科技): $919 million into a U.S. subsidiary for optoelectronic products and server power-supply manufacturing.
This reflects a broader shift — not just chip fabrication but assembly and power-supply links in the supply chain are also moving stateside.
What do the Formosa Plastics Group moves actually mean?
Nan Ya Plastics (南亞塑膠) injected $1 billion into an offshore subsidiary, but mainly for USD time deposits and hedging costs — not direct capacity expansion.
Formosa Plastics (台塑) used its existing U.S. subsidiary equity (about $292 million) to subscribe for new shares — an internal restructuring.
In plain terms = the Formosa Plastics money is largely a treasury operation, quite different from the "build a factory" investments by TSMC and Quanta.
What does the full approval batch look like?
The Commission approved 9 major investment cases: 7 outbound totaling roughly $23.05 billion, and 2 inbound totaling roughly $2.114 billion.
TSMC's single $20 billion case accounts for 87% of total outbound investment — the dominant item by far.
The two non-U.S. outbound cases: Taiwan Union Technology (聯合科技) invested about $48 million in a Thai subsidiary for copper-clad laminate production; Fubon Life (富邦人壽) invested about $190 million in a Jersey subsidiary for real-estate leasing.
