Does All Semiconductor Manufacturing Depend on Spruce Pine Quartz? (2024)
Here’s an idea you see spreading across the internet every so often: that all semiconductor and solar PV manufacturing depends on extremely pure quartz from the town of Spruce Pine, North Carolina. This quartz is used to make the crucibles which hold the molten silicon as it gets turned into silicon ingots, which are then cut into wafers and made into chips. The quartz needs to be very pure to prevent impurities from seeping into the silicon, and Spruce Pine is where this very pure quartz comes
