Gas
As the demand for dry processing steps has increased, so has the importance of contamination control for CVD, Etch, Epitaxial, Ion Implant, and PVD gases used during the manufacture of semiconductor devices.
While material suppliers provide ultra high purity gases, the end user must be able to maintain that purity level while eliminating any contamination from the gas delivery system. Proper filtration for bulk, point-at-distribution, and point-of-use applications is absolutely critical in maintaining an ultra high purity gas system.
