Micron pauses $4.5 billion Taiwan chip plant amid union dispute

Micron Technology has hit pause on its planned $4.5 billion memory chip plant in Taiwan amid a labor fight that has escalated faster than most of the industry expected.

The suspension, reported on November 5, 2026, covers Fab 11E in Taoyuan. That facility was meant to help Micron keep pace with the AI boom, which needs memory almost as badly as it needs electricity.

What happened at Fab 11E

Micron cited growing uncertainty around its labor negotiations as the reason for halting construction. The company says it has briefed Taiwanese officials and its suppliers on the situation.

The trigger was a warning strike by the Taoyuan union on October 22. That walkout marked the first strike in Taiwan’s semiconductor sector.

The union represents between 2,300 and 3,000 workers. The Taoyuan site itself employs about 3,000 people, so the union speaks for most of the local workforce.

Its demands are ambitious. The union wants a one-time bonus worth 83 months’ salary, or nearly seven years of pay delivered in a single check.

It also wants a profit-sharing mechanism that would hand workers 15% of quarterly operating profits. Micron put counter-offers on the table, and the union judged them inadequate.

A tale of two unions

Not every Micron site in Taiwan is in conflict. The larger Taichung union reached a labor-management agreement with the company on October 21, one day before the Taoyuan warning strike.

Micron has reaffirmed that operations at its other Taiwanese sites will continue as normal.

Why Fab 11E mattered

Fab 11E was designed to use extreme ultraviolet lithography to produce advanced DRAM. DRAM is the fast, short-term memory that computers and servers use while they work. AI systems consume huge quantities of it, which is why memory makers have been racing to add capacity.

The plant’s budget has been reported in a range of $3 billion to $4.5 billion. Some sources note total spending could reach $4.5 billion once equipment from ASML, the Dutch lithography toolmaker, is included.

The goal was to expand Micron’s output as AI-related memory supply pressure builds. In that race, Micron competes directly with Samsung and SK Hynix.

Taiwan’s outsized role in Micron’s business

Taiwan accounts for 50% to 60% of Micron’s total output. Micron employs approximately 15,000 workers there. Its cumulative investment in Taiwan exceeds NT$1.6 trillion, or around $50 billion, making it the largest foreign investor in the region.

The Taoyuan site employs about 3,000 of those workers, and more than half of what the company produces comes from the island.

What this means for Micron and the memory market

The pause could limit Micron’s ability to respond to AI-driven memory demand. If delays drag on, it could contribute to supply tightness and weigh on Micron’s position relative to Samsung and SK Hynix.

The Taichung agreement offers a possible template. If Micron and the Taoyuan union find terms somewhere between the current offers and the 83-month bonus request, construction could resume. If not, further strikes remain on the table.

Taiwan’s chip sector has now seen its first strike, and that precedent does not disappear once one deal is signed.
