PC100 Series

PC100 Series Metal Sealed Pressure Controllers

Accuracy under pressure. Precision under control.

Models PC115 / PC125

The PC100 Series pressure controllers and meters combine a host of high-performance technology features to deliver a new level of pressure control accuracy and reliability to demanding semiconductor, vapor deposition and other ultra-precise manufacturing processes.

Built on the proven Brooks GF100 mass flow controller technology, the PC100 Series features a high-purity all-metal flow path, enhanced sensor technology engineered specifically to eliminate sensor drift and a user interface and device diagnostics capability that makes it much easier to conduct device evaluation and troubleshooting, resulting in limited service interruption and reduced downtime.

  • DeviceNet™ protocol
  • High-performance components enable fast response and setting time for improved pressure control
  • Reduced diverted gas consumption and associated abatement costs
  • All metal, corrosion resistant SEMI F20 compliant wetted flow path with overall reduced surface area and un-swept volumes ensures faster dry-down during purge steps
  • Long-term thermal or pressure sensor device stability maximizes yield and throughput
  • User-programmable start-up function for processes requiring a slow-ramped pressure control
  • Semiconductor advanced etch tools
  • Thin-film chemical vapor deposition systems (CVD, MOCVD, PECVD, ALD)
  • Physical vapor deposition (PVD) systems
