Introduction
Building a semiconductor fabrication plant (fab) is one of the most complex, expensive, and time-consuming engineering feats in modern industry. With the global demand for semiconductors surging due to advancements in artificial intelligence, electric vehicles, and consumer electronics, companies like Intel, TSMC, and Samsung are investing heavily in new fabs.
A state-of-the-art CMOS (Complementary Metal-Oxide-Semiconductor) fab can cost between $10 billion and $20 billion, take three to four years to complete, and require thousands of workers and highly specialized equipment.
This article dives into the staggering scale, cost, and effort involved in constructing these cutting-edge facilities.
Key Facts About Semiconductor Fab Construction
Massive Investment – Building an advanced fab can cost over $20 billion, making it one of the most expensive industrial projects.
Time-Intensive Process – It takes around three to four years to construct and operationalize a new semiconductor fab.
Extensive Workforce – Up to 7,000 construction workers are needed to build the facility.
Heavy-Duty Equipment – Fabs house over 1,200 high-tech tools and 1,500 utility equipment pieces to support operations.
Enormous Infrastructure – The materials used in construction exceed those used for iconic structures like the Burj Khalifa and the Eiffel Tower.
Breaking Down the Semiconductor Fab Construction Process
Cost and Investment
A modern semiconductor fab requires a huge financial commitment. The price tag has surged in recent years, with the most advanced fabs surpassing $20 billion.
This massive investment covers:
- Land acquisition and site preparation
- Advanced cleanroom facilities
- High-precision semiconductor manufacturing equipment
- Utility and support infrastructure
Intel, TSMC, and Samsung are leading the charge, with multi-billion-dollar fabs under construction in the U.S., Europe, and Asia.
Intel’s upcoming Ohio fab alone is expected to cost $20 billion, while TSMC’s Arizona project will exceed $40 billion with future expansions.
Workforce and Labor Hours
The sheer manpower required to build a semiconductor fab is staggering. It takes about 7,000 construction workers and engineers to complete a fab.
The total labor hours can exceed 15 million, which is equivalent to 1,700 calendar years of work.
Specialized tradespeople: Electrical engineers, cleanroom specialists, and industrial construction workers are in high demand.
On-Site workforce: Thousands of people work together to assemble intricate tools, lay down precision wiring, and construct the vast cleanroom spaces.
Equipment and Heavy Machinery
Fabs require some of the most advanced and expensive manufacturing tools in the world. These tools are essential for producing chips at nanoscale precision.
- 1,200+ fabrication tools: These include photolithography machines, etching systems, and deposition tools.
- 1,500+ utility equipment pieces: These support the cleanroom environment, power systems, and chemical processing.
- ASML’s EUV Lithography Machines: The most advanced chipmaking machines, which cost over $200 million per unit.
The heaviest pieces of equipment are chillers, weighing 55 tons each—equal to 12 adult African elephants.

Infrastructure and Materials
The construction of a semiconductor fab requires an enormous amount of material, often surpassing that used in some of the world’s most iconic structures.
- 2 million cubic yards of soil and rock are excavated—enough to fill The Ohio State University football stadium.
- 500,000 cubic meters of concrete are poured, more than twice the amount used for the Burj Khalifa.
- 100,000 tons of steel reinforcement are installed.
- 58,000 tons of structural steel—8X the weight of the Eiffel Tower—are used.
Additionally, over 23 million feet of cables are laid—equal to the length of 166 full marathons.
Cleanroom Facilities and Precision Engineering
Semiconductor fabs operate in highly controlled cleanroom environments where even a microscopic particle can ruin a chip.
- Each fab includes a 250,000+ square-foot cleanroom, big enough to fit four American football fields.
- Cleanrooms must maintain strict air purity levels, often 1,000 times cleaner than a hospital operating room.
- Temperature and humidity are tightly controlled to prevent material expansion or contamination.
These cleanrooms house multi-million-dollar lithography machines that enable chipmakers to etch circuits at 3-nanometer and beyond scales.
