Global – October 24, 2026 -- The semiconductor industry is projected to reach a market value of $1 trillion by 2030-2032, built on a production chain that spans several continents and thousands of precision steps.
Wafer size of 300mm dominates modern fabrication for higher chip yield
Production starts with refining sand into ultra-pure silicon, the second most abundant element in Earth's crust at about 28%. The silicon is melted, cooled into ingots, sliced into wafers and polished. Wafers come in 150mm, 200mm and 300mm diameters, and the 300mm format is the most widely used because it yields more chips per wafer. Thickness ranges from 0.7mm to 1mm, and weight from 30g to 125g depending on diameter.
EUV lithography at 13.5 nm enables nodes below 7 nm
Photolithography sets the circuit blueprint. Deep ultraviolet (DUV) systems use 193 nm light, while extreme ultraviolet (EUV) systems operate at 13.5 nm and enable advanced nodes below 7 nm. A shorter wavelength allows higher transistor density and better performance.
Etching, deposition, ion implantation, metallization and chemical mechanical polishing follow, and the sequence is repeated multiple times to build up circuit layers. Wafers are cleaned with high-purity water between steps.
Back-end testing filters defective dies before packaging
After front-end processing, electrical tests screen out defective chips. Wafers are then thinned by backlapping and diced into dies by laser or diamond-saw cutting. Dies are bonded to a substrate, connected by wire bonding or flip-chip technology, and encapsulated. Final electrical, temperature, stress and burn-in tests precede shipment.
Supply chain runs from the US and Japan to Taiwan, Malaysia and Europe
A single chip may combine components developed in the United States, front-end fabrication in Taiwan or South Korea, chemicals from Japan, and tools from the Netherlands or the US. Back-end processing is done in Malaysia, and testing in Europe. This interdependence leaves the industry increasingly exposed to geopolitical tensions.
