Metrology for trace water in ultra-pure process gases

Project: EU project

Project Details

Description

Reliable humidity measurements for high-purity manufacturing

Water vapour is the single largest contaminant in high-purity processing of products such as microelectronics, OLEDs and MEMS devices. Currently, measurements of trace water in ultra-pure process gases lack traceability.

Project will develop improved methods for trace water measurement relevant to the production and use of pure process gases and demonstrate the relevant metrology practices in the industry supply.

VTT MIKES improves its thermodynamic saturation-based trace water standard to extend the lower limit of frost-point temperature to –100 °C and at pressure up to 0.11 MPa. This makes possible
the generation of nitrogen and air with trace levels of water vapour.
