Global 8-inch Wafer market was valued at USD 4,104.80 million in 2023 and is projected to reach USD 5.18 billion by 2034, expanding at a CAGR of 2.1% during the forecast period 2026–2034. The market is exhibiting stable growth supported by sustained demand for mature-node semiconductor production and cost-efficient fabrication platforms.

An 8-inch wafer, also known as a 200mm silicon wafer, is a circular semiconductor substrate used in the fabrication of integrated circuits (ICs), discrete devices, and sensors. These wafers are manufactured from high-purity monocrystalline silicon and serve as the foundational platform for photolithography, doping, etching, and thin-film deposition processes.
