Si1-xGex brings about new metrology challenges with respect to process control, like mapping of the Ge homogeneity of deposited films. X-ray fluorescence spectrometry provides a fast and non-destructive solution in this respect, yielding high precision results.
The PANalytical 2830 ZT determines layer composition, thickness, dopant levels and surface uniformity for a wide range of process films and stacks.
