Global Gallium Arsenide (GaAs) Epitaxy market is experiencing robust growth, with a valuation of USD 1.62 billion in 2025 and projected expansion to USD 2.98 billion by 2032, growing at a CAGR of 7.8%. This upward trajectory is fueled by rising demand for high-frequency semiconductors in 5G networks, photonic devices, and advanced automotive applications where GaAs outperforms traditional silicon. Gallium Arsenide Epitaxy involves depositing crystalline layers of GaAs on substrates using precision techniques like Metal-Organic Chemical Vapor Deposition (MOCVD) or Molecular Beam Epitaxy (MBE). These epitaxial structures enable superior electron mobility for critical applications ranging from smartphone RF components to satellite communications, with major foundries currently operating at 85-90% capacity utilization to meet demand.
