With the rapid advancement of semiconductor chip and MEMS sensor industries, high‑end smart manufacturing sets rigorous standards for production‑site cleanliness and waste‑gas emission compliance.
Core production workflows including semiconductor etching, wafer cleaning, chip packaging & testing, and sensor R&D continuously generate mixed acid‑alkali waste gas and VOCs. Improper abatement not only impairs precision equipment performance and product yield, but also brings substantial environmental compliance risks. For semiconductor manufacturers, a stable, high‑efficiency and custom‑engineered waste‑gas treatment system is therefore a critical foundation for safe, clean and environmentally‑responsible operations.
For years, CADAIR has specialized in developing and deploying waste‑gas abatement solutions tailored to high‑end semiconductor manufacturing. Backed by proprietary technologies, proven solutions and full‑cycle support services, CADAIR delivers reliable environmental protection for a broad portfolio of semiconductor and sensor manufacturers.
Recently, a batch of CADAIR VOCs and waste‑gas treatment projects across Beijing, Shanghai and Zhejiang have passed final acceptance and entered official operation. These projects serve multiple high‑end semiconductor segments, covering scientific instrumentation & equipment, image‑sensor packaging‑and‑testing, and MEMS sensor manufacturing.
