[Analysis Case] Evaluation of SiC Power MOSFET Dopants by SIMS

Imaging SIMS enables the evaluation of localized elements.

We disassembled a commercially available SiC power MOSFET and conducted imaging SIMS measurements to evaluate the concentration distribution of the dopant elements Al, N, and P in a 20 µm square area to a depth of 0.5 µm. We will present a case where we extracted the depth profile concentration distribution of Al, N, and P localized within the sample surface from the data processing after the imaging SIMS measurements.
