[Analysis Case] SiC by SIMS

Imaging SIMS allows for the evaluation of localized elements.

We disassembled a commercially available SiC Schottky diode and conducted imaging SIMS measurements to evaluate the concentration distribution of the dopant element Al in a 40μm square area to a depth of 0.5μm. From the data processing after the imaging SIMS measurements, we extracted the depth-wise concentration distribution of Al localized within the sample surface and present a case study comparing the concentration distributions for each pattern.
