Estimating Hydrochloric Acid and Ammonium Hydroxide Loss
Calculations suggest break-through from semiconductor bulk chemical distribution systems occurs in a matter of days and steady state permeation accounts for several milliliters of chemical loss each day.
Estimating Drying Times, Break-through Times, Permeation Rates, and Post-Purge Outgassing For Microenvironments
In the future, microenvironments will be required to maintain low oxygen and relative humidity levels to facilitate newer technology nodes.
