TSMC, the world's largest contract chipmaker, is looking at factory equipment that can run without rare-earth components, according to a Reuters report on Thursday. The move is part of an effort to reduce the company's exposure to potential Chinese export restrictions on these critical minerals.
Rare earths are a group of 17 metals used in high-performance magnets, which are found in electric motors across industrial automation. These motors are essential for the automated machinery inside TSMC's semiconductor fabrication plants, or fabs. By asking suppliers about rare-earth-free motors, TSMC is aiming to remove a small but important supply-chain chokepoint.
Why rare earths matter in chipmaking
While most attention in the chip industry focuses on lithography machines and advanced manufacturing nodes, the factory equipment that moves wafers, handles materials, and controls environments also relies on precision motors. Many of these motors use rare-earth magnets because they offer high power in a compact size. If those magnets become hard to source, the impact could be felt far beyond the chip itself.
The idea is less about changing the chips TSMC makes and more about protecting fab "uptime" — keeping production lines running. A missing motor or spare part can idle an entire tool until a replacement is sourced, installed, and certified. In a highly automated fab, even a single component failure can cause costly delays.
The talks are still early and not widely adopted, but they fit a broader shift: governments and manufacturers are mapping dependencies deeper into the supply stack, especially where China dominates processing and exports. China is the world's largest producer and exporter of rare earths, and it has previously used export controls as a geopolitical tool.
Parallel efforts to diversify critical minerals
Reuters also noted parallel efforts in Taiwan and the US to diversify critical-mineral sourcing, which could support these kinds of redesigns over time. Taiwan, where TSMC is based, has been working to secure supplies of rare earths and other strategic materials. The US has also taken steps to boost domestic production of critical minerals, including rare earths, as part of broader supply-chain resilience efforts.
These efforts are not just about TSMC. Other chipmakers and industrial companies are likely watching closely. If rare-earth-free motors become viable, they could reduce a single-point-of-failure input across the entire semiconductor supply chain.
What it means for investors
For investors watching the chip supply chain, the key point is that resilience isn't only about lithography machines and advanced nodes. If export controls tighten, rare-earth-based motors and replacement parts inside factory automation could become harder to get, raising the risk of unplanned downtime and delayed shipments.
By exploring alternatives now, TSMC is trying to reduce a single-point-of-failure input in its equipment stack, which can make its delivery timelines — and the downstream supply of chips to customers — less sensitive to a geopolitical squeeze, even before any broad rollout.
This is part of a wider trend in the semiconductor industry. Companies are increasingly looking at ways to secure their supply chains, from Nvidia's $1.1 billion prepayment to lock in chipmaking capacity to ASML's warning that chipmaking tool shortages could stretch to 2028. The industry is also dealing with rising costs, as seen in ASML's plan to raise chipmaking part prices by 10% in South Korea.
For everyday investors, this story underscores that the chip industry's health depends on more than just demand for smartphones and data centers. It also depends on a complex web of materials and components, some of which are concentrated in a few countries. Any disruption in that web can ripple through the entire market.
While TSMC's exploration of rare-earth-free motors is still in its early stages, it signals that the company is thinking ahead about geopolitical risks. That kind of foresight can be a positive sign for investors, as it suggests management is proactive about protecting long-term production capacity.
However, it's important to note that this is not a quick fix. Developing and certifying new motors for use in advanced fabs takes time. And even if TSMC successfully adopts rare-earth-free motors, other parts of the supply chain may still rely on rare earths. Still, the move is a step toward greater resilience.
For those interested in the broader rare-earth market, the news also highlights the strategic importance of these minerals. Saga Metals' rare earth project and Shenghe's sale of control of four rare earth units to a state group are examples of how the sector is evolving. As companies and governments seek to diversify supply, such projects could gain more attention.
In the meantime, investors should watch for any signs of tightening export controls and how TSMC and other chipmakers respond. The ability to adapt to supply-chain challenges will be a key factor in determining which companies thrive in the coming years.
