CRDS High Purity Resources

中文文档和资源 – CN Resources

Based upon our Cavity Ring-Down Spectroscopy (CRDS) gas analyzer performance, the SEMI F-112 standard calls out CRDS as the technology of choice in determining moisture dry-down characteristics of high-purity gas systems. To check incoming or point-of-use quality, Our CRDS analyzers monitor for O₂, H₂O, CH₄, CO, CO₂ and more down to parts-per-billion (ppb) and even parts-per-trillion (ppt) levels. A special low-pressure version, the HALO LP monitors for impurities in hydrides, including arsine, phosphine and ammonia. If low-ppb moisture measurement in pure ammonia is required, the ALOHA+ H₂O specializes in this application.

The high potential for atmospheric leaks during cylinder and truck fill, as well as in gas delivery, storage and distribution systems, drives the requirement for continuous on-site production monitoring at the world’s leading semiconductor fabs. Typically, H₂, N₂, Ar, He and O₂ are monitored for trace H₂O, O₂ and CH₄ contamination. Other contaminants that may be monitored are CO, CO₂, and acid gases.

The recent addition of air and CDA to the measurement list addresses the latest Lithography requirements. For qualifying new gas lines and welds, dry Ar and N₂ are typically used. To ensure gas quality throughout the fab, monitoring is also performed at gas cylinders, in addition to the lines following a cylinder exchange and at purifiers to verify their functionality.
