TFT-LCD Manufacture

Innovating the TFT-LCD flat panel market with a full portfolio of high-purity gases and chemicals, flanked by a global presence and value-added technologies

We deliver a wide range of value-added technologies to help you meet your specific cost and environmental challenges.


On-site fluorine generation
We pioneered the use of molecular fluorine (F2) to replace gases with a high global warming potential such as nitrogen trifluoride (NF3) and sulphur hexafluoride (SF6). These are currently used to clean chemical vapour deposition (CVD) chambers in the manufacture of flat panel displays. Our Generation-F® On-Site fluorine generators deliver the most effective cleaning gas available, reducing cleaning time by over 50%, reducing tool downtime and improving line throughput by up to 10%.

Nitrogen generation
Our SPECTRA-N™ nitrogen generators are the most cost-effective and reliable way of supplying ultra-pure nitrogen in the large quantities needed by TFT-LCD manufacturers. With gas impurity levels below 1ppb, the SPECTRA-N consumes less power than conventional generators and also provides excellent turndown capabilities to meet facility ramp-up requirements.

Full spectrum
We offer the full range of gas and chemical products to support all TFT-LCD flat panel manufacturing processes:

  • Ultra-pure bulk gases 

  • On-site gas generators 

  • Electronic special gases in cylinder and bulk supply 

  • Special and wet process chemicals.
