Vacuum Pump Spares for Semiconductor
Vacuum pump spares for semiconductor fabs and equipment OEMs — Edwards iXM/iXH/iXL primary pumps, Pfeiffer HiPace and Edwards STP turbomolecular, Ebara A-Series, Kashiyama, plus mechanical boosters. SEMI-aware change-control documentation, fab-stock partnerships, next-day UK delivery.
Vacuum pumps are used in semiconductor manufacturing for wafer processing — including etch, CVD, PVD, ALD, ion implantation, EPI, EUV/photolithography, and load-lock and transfer-chamber evacuation.
Where vacuum is used in Semiconductor
We supply spare parts to support every vacuum-based process in this sector — from frontline production equipment to laboratory and quality-assurance instrumentation.
Plasma and reactive-ion etch (RIE)
Corrosive halogen chemistries (Cl₂, HBr, F₂) on metal and dielectric etch chambers.
LPCVD, PECVD, HDP-CVD, SACVD, ALD deposition
High powder load, condensable byproducts, requiring purge nitrogen and heated-pump configurations.
PVD / sputtering
Metallisation and barrier layer deposition for interconnects.
Ion implantation
Source vacuum and end-station vacuum on ion implanters.
EUV lithography scanner vacuum
Hydrogen and Sn debris management on extreme ultraviolet lithography tools.
Wafer load-locks, transfer modules, vacuum robotics
Cluster-tool transfer chambers cycling between atmosphere and process vacuum.
MOCVD for compound semiconductors
GaN, GaAs, SiC epitaxial deposition for power electronics and RF devices.
EPI reactors and rapid thermal processing (RTP)
Silicon and silicon-germanium epitaxial growth with vacuum-controlled atmospheres.
Which pump types are used and why
Different applications in semiconductor drive different pump-technology choices. We support the full breadth of pump types installed in this sector.
Brand Affinities
- •Edwards is the dominant primary-pump brand in fabs globally — iXH Mk2 launched at SEMICON for ultra-harsh processes
- •Ebara and Kashiyama are strong in Asian fab footprints
- •Pfeiffer and Edwards lead on turbomolecular
- •Shimadzu has share on tool OEM platforms (TEL, AMAT, LAM) where pump models are specified in the BOM
Dry primary pumps
Edwards iXM (clean to light-harsh), iXH (harsh chemistry, powder), iXL (light duty); Ebara A-Series; Kashiyama. Hydrocarbon-free operation is mandatory to prevent wafer contamination.
Turbomolecular pumps
Edwards STP, Pfeiffer HiPace, Shimadzu, Leybold MAG on etch, PVD, and load-locks for high vacuum.
Mechanical boosters (Roots blowers) in series
Boosting throughput on high-throughput etch and CVD chambers.
The cost of vacuum downtime in semiconductor
A leading-edge fab running 60,000 wafer starts/month can lose $1M–$5M per hour of unplanned downtime, with scrapped in-process lots and tool re-qualification on top. Industry analyst data indicates fab managers spend 40–70% of time firefighting unplanned equipment failures. Pumps are typically swap-out modules with on-site spares pools — refurbishment partners and rapid spares supply are critical.
Powder accumulation in pumping mechanism on CVD/etch (WF₆, TEOS, SiH₄ residues)
Mechanism overhaul kits, purge orifices, exchange units
Corrosion of internal coatings under HCl, HBr, F₂ chemistries
Tip seals, shaft seals, internal coating refurb
Booster bearing wear under continuous duty
Bearing kits and gear sets
Turbo crash damage from particle ingress on chamber vents
Full rotor replacement / pump exchange
Purge nitrogen flow failure causing condensation
Purge orifices, flow regulators, controller boards
