Semiconductors are considered the brains of modern electronics. Our TIGER OPTICS™ Cavity Ring-Down Spectroscopy (CRDS) gas analyzers seamlessly detect parts-per-billion (ppb) and parts-per-trillion (ppt) levels and delivers bulk gas monitoring for trace H₂, H₂O, O₂, CH₄, CO, CO₂, Kr, NH₃, and Xe, UHP ammonia for HB LED production, tool monitoring for trace H₂O and HF, and continuous AMC monitoring for ambient HCl, HF, and NH₃. 

Specialty gases of superior quality play a vital role as raw materials and process gases across various industries. From carbon dioxide in beverages to ammonia in LED manufacturing and silane in semiconductor fabrication, maintaining high purity standards for specialty gases is critical. The presence of moisture impurities, for instance, can significantly impact the efficiency of resulting LEDs. The semiconductor industry demands ultra-high purity gases, whether it’s silane or germane for epitaxy, fluorine compounds for etching processes, or cleaning gases. Process Insights offers highly sensitive, accurate, and user-friendly analysis instruments. These instruments utilize the renowned Cavity Ring-Down Spectroscopy (CRDS) technique and cater to a wide range of specialty gases and applications.
