In the semiconductor industry, PGMEA is a commonly used solvent, primarily for the application of surface adherents such as Bis(trimethylsilyl)amine (HMDS) on silicon wafers.[7] The compound is often the most abundant airborne, molecular contamination (AMC) in semiconductor cleanrooms,[8] due to its evaporation into ambient air.
