The semiconductor industry worldwide depends on a single quartz factory located in Spruce Pine, North Carolina.
The world’s semiconductor industry relies on a single quartz factory in Spruce Pine, North Carolina, notes Wharton School professor Ethan Mollick. This bold statement underscores the prominence of the seemingly ordinary plant operated by Sibelco North America Inc. in the global technology industry.
The he mined here ultra-pure quartz is vital to the production of crucibles for refining the silicon wafers that form the basis of semiconductor chips. Despite many companies supporting the semiconductor industry, such as Intel, TSMC and Samsung, as well as renowned technology areas such as Silicon Valley and Hsinchu Science Park, Spruce Pine’s uniqueness stands out strongly.
Its importance is also emphasized by the fact that any adverse event at this site could have global consequences and potentially jeopardize the entire chip manufacturing industry. The geological origin of Spruce Pine dates back to about 380 million years ago, when very high purity minerals were formed under the earth’s surface during the collision of Africa and North America. These minerals, which were formed under unique conditions, without the influence of water that threatens purity, have been utilized for centuries. The Spruce Pine mine provided not only quartz, but other minerals such as feldspar, which are used in many places.
Its historical importance is also shown by the fact that Thomas Edison used the minerals from the Spruce Pine mine in 1879 for his first electronic experiments. Today, the quartz extracted from this mine has unprecedented optical, mechanical and thermal properties that are essential for semiconductors, solar cells and optical fibers.
Mollick warns that while synthetic techniques exist to produce quartz, the sudden closure of the mine could cause serious disruption to the semiconductor industry. This can result in high costs and delays in the production of electronic devices vital to the modern economy.
In summary, Spruce Pine plays a crucial role in the global semiconductor ecosystem, demonstrating that even a single factory can have a significant impact on the global economy. Its importance highlights the need to diversify supply sources and invest in new technologies to ensure the resilience of the technology industry.
