As the global semiconductor manufacturing process advances below 2nm, wafer fabs are demanding increasingly stringent cleanroom environments. This has rapidly boosted demand for airborne molecular contamination (AMC) solutions from major suppliers such as Greenfiltec, Yesiang, and Sweden’s Camfil. Driven primarily by TSMC’s aggressive capacity expansion and rapid progress in advanced nodes, these companies have recently faced rare supply tightness, sparking a new wave of price increases.
