FIB polishing of CdTe
Cadmium Telluride composite material was milled by a focused ion beam (FIB) using different ion doses. Using the LiteScope inside the SEM chamber, we could easily localise to the region of interest and in-situ investigate each area separately, resulting in a roughness-ion dose relation.
This surface analysis was done in-situ right after the FIB milling without chamber evacuation. As a result, it became possible to find the optimal parameters of polishing CdTe material and to do a surface quality control to keep desired surface roughness.
Measurement modes: Topography
- fast and easy ROI identification
- in-situ conditions: combined AFM and SEM analysis of sensitive sample
- depth and height profiling with sub-nm precision
