North Carolina’s Silicon Mines: Leverage for the US?

While the quartz from this mine can be used to make semiconductor-grade silicon and the ultra-pure crucibles needed to grow silicon crystals, this isn’t the kind of leverage that’s going to have everyone else bending the knee. The US is already a leader in this space, but given the complexity of semiconductor supply chains, no single country controls a majority.

The US and allies dominate the high-end stuff, but none of this works without all 30,000 inputs and 100,000 steps. So, does it give the US some leverage? Sure. But that doesn’t change the fact that we still depend on a fragile, global supply chain for semiconductors. We’d need about $20 trillion and 40 years if we wanted to do it on our own…
