(TECH SPOT) – Ultra-high-purity quartz is an essential component to semiconductor chips, and the only places in the world that can meet this need are two mines in a small North Carolina town. The mines’ owner, Sibelco, is investing $700 million to expand capacity, but is that enough to keep up with AI-fueled chip demand?
Spruce Pine is a small town about two hours drive northwest of Charlotte, NC. You can get to the general area via a number of ways, depending on your point of origin, but for the last stretch of the trip, you need to travel down Fish Hatchery Rd. It’s a two-lane rural highway, as depicted in Google Maps, set amid a pleasant scenic backdrop.
It’s on this road that the modern economy rests, according to Wharton associate professor Ethan Mollick, who teaches innovation and entrepreneurship and also examines the effects of artificial intelligence on work and education. That’s because the road runs to the two mines that are the sole supplier of the quartz required to make the crucibles needed to refine silicon wafers.
