Overview.

The IMP-EPD is a differentially pumped, ruggedized secondary ion mass spectrometer for the analysis of secondary ions and neutrals from the ion beam etch process. The system includes integrated software with process specific algorithms developed for optimum process control.

The IMP-EPD system is process proven for the production of high specification thin film devices, for applications including magnetic thin films, high temperature superconductors and III-V semiconductors.

During milling, ions with a mass characteristic of the material to be etched are monitored, and their rapid response to step changes in signal intensity provides for precise determination of end points and material interfaces.
