Soaring semiconductor demand drove critical subsystems sales to record levels in 2021. Total critical subsystems sales surged 33% last year, closing in on the $20B mark. The fastest growing segments in 2021 were Abatement Subsystems, Mass Flow Controllers, Ozone Generating Subsystems, and Lithography Optics. Certain other segments were hobbled by supply chain issues and unable to meet demand due to production limitations.

The top 10 vendors in the critical subsystem market include ZEISS, MKS Instruments, Edwards, Horiba, Advanced Energy, VAT, Ultra Clean Technology, Ichor Systems, ASML, and EBARA. 2021 was a strong growth year for all of the top 10 vendors, with Horiba recording the fastest sales growth of over 50%. These companies design, manufacture, and support various markets including Fluid Management Subsystems, Integrated Process Diagnostics, Optical Subsystems, Power and Reactive Gas Subsystems, Thermal Management Subsystems, Vacuum Subsystems, Wafer Handling Subsystems, Integrated Subsystems, and Other Subsystems.
