Introduction
Wet etchants, liquid-phase chemical solutions used in microfabrication, are critical for selectively removing materials from semiconductor wafers, flat panel displays (FPDs), and solar cells during manufacturing. As one of the earliest developed etching techniques, wet etching remains widely utilized in semiconductor production due to its cost-effectiveness, compatibility with various substrates, and ability to achieve isotropic and anisotropic etching. Common wet etchants include hydrofluoric acid-based mixtures for silicon and silicon dioxide, phosphoric acid for silicon nitride, and acid blends (e.g., phosphoric, nitric, and acetic acids) for metals like aluminum. The market is driven by the global surge in semiconductor demand, fueled by technologies like 5G, artificial intelligence, and electric vehicles, alongside growth in FPDs and solar energy. Key players like GREENDA, advancing a 10,000-ton electronic materials project with 15,000 tons of buffered oxide etchant (BOE) capacity, and Runma Chemical, with 29,780 tons of high-performance etchant capacity, highlight the industry’s scale. Challenges include stringent environmental regulations, raw material price volatility, and competition from dry etching, while trends such as eco-friendly etchants, high-purity formulations, and advanced 12-inch wafer technologies shape the market’s future. Asia Pacific dominates production and consumption, driven by semiconductor foundries like TSMC and UMC.Market Size and Growth Forecast
The global wet etchant market is projected to reach USD 2.5-3.0 billion by 2025, with an estimated compound annual growth rate (CAGR) of 6%-8% through 2030. This growth is propelled by rising demand for semiconductors, FPDs, and solar cells, supported by technological advancements in 12-inch wafer fabrication and increasing investments in electronics manufacturing.Regional Analysis
