| مستخلص: |
The combination of the high-brightness He+/Ne+ atomic level ion source with secondary ion mass spectrometry detection capabilities opens up the prospect of obtaining chemical information with high lateral resolution and high sensitivity on the Zeiss ORION helium ion microscope (HIM). The analytical performance in terms of lateral resolution and sensitivity was investigated. The effect of the secondary ion extraction field on the probe size of the HIM and the transmission of the extraction system were studied using SIMION. Probe sizes <10nm and sensitivities in the ppm range are possible using a set of extraction electrodes consistent with the geometry of the ORION instrument. [ABSTRACT FROM AUTHOR] |
