Applications
Applications of Molecular Pumps in Various Industries
Molecular pumps are high-vacuum pumps widely used in industries requiring clean, oil-free high-vacuum or ultra-high-vacuum environments. Their main application areas include:
-
Semiconductor and Integrated Circuit Manufacturing
-
Used in chip fabrication processes like lithography, etching, ion implantation, and thin-film deposition (CVD, PVD)
-
Ensures oil-free operation to prevent wafer contamination
-
Key equipment: Electron beam lithography systems, plasma etchers, MBE systems
