Vertex RFEA System
The Vertex Retarding Field Energy Analyser (RFEA) system measures the Ion flux and Ion energy distribution function (IEDF) incident on a surface in real time using an imitation substrate with replaceable, integrated sensors. The Vertex system can also measure these parameters for a range of configurable Aspect Ratios (ARs) ranging from 0.5 to 20, with a resolution of 0.5, to understand their influence on deep trench etching.
