Un sistema UHV di analisi superficiale per la caratterizzazione dei film sottili

Misura la composizione superficiale dei primi pochi nanometri e/o micron di campioni solidi

La Workstation SIMS permette SIMS statico e dinamico ad alte prestazioni per una dettagliata analisi della composizione superficiale e per il profiling in profondità.

Overview

The SNMS facility complements the SIMS technique, providing quantification for thin film composition measurements.

Hiden’s new SIMS-on-a-Flange provides a complete SIMS facility on a single UHV conflat type flange.
