Semiconductor Wafer Processing: Ultra-Clean FFKM Seals for Plasma Environments
Semiconductor plasma etching and deposition processes demand seals that survive aggressive fluorine chemistry without contaminating wafers. This article examines FFKM perfluoroelastomer seal selection for etch chambers, CVD tools, and wafer handling — comparing FFKM grades for plasma resistance, particle generation, and outgassing.
