A mass and energy analyser for plasma diagnostics

Hiden plasma probes measure some of the key plasma parameters and provide detailed information relating to plasma reaction chemistry.

PSM mass and energy analyser for plasma diagnostics


A wide range of industrial processes use electrical plasmas, and new applications are developing rapidly. In the microelectronics industry the demands of higher yields and shrinking device geometries mean that process reproducibility and understanding is vital.

Detailed understanding of the reaction kinetics of plasma ions and neutral species plays a key role in the development of advanced surface engineering processes such as HIPIMS.
