The Sensors
All INFICON Quartz crystal sensors utilize plane-convex 6 MHz crystals. Their high quality guarantees
smooth and reproducible operation of the INFICON instruments. Frequent feedback from our customers
indicates that this is not necessarily the case for the Quartz crystals offered by other vendors.
Besides the standard sensor a compact sensor for systems with only limited space is offered.
For UHV applications INFICON offer a sensor which can be baked up to 450°C. Furthermore, a
sensor for sputter processes is available incorporating a magnetic field to repel energetic
electrons.
In some very sensitive applications a single sensor would impose a process risk because of its
limited lifetime or the always present chance of failure. For those cases INFICON offer two
multiple crystal sensors, the dual sensor head and the CrystalSix®. These sensors ensure
process safety. In deposition processes with more than one deposition source they may also be
used to monitor and control each source with a dedicated sensor crystal.
