[Analysis Case] Composite Evaluation of the Active Layer of SiC Power MOSFETs

Evaluate the shape of the active layer and the dopant.

We will introduce a case study evaluating the distribution of the diffusion layer in commercially available SiC power MOSFET devices. In the SiC MOSFET manufacturing process, the channel is formed through ion implantation, activation heat treatment, and epitaxial layer formation. During the active layer formation process, we understood the device structure through TEM observation and evaluated the diffusion layer distribution of the p-type/n-type cross-section and the epitaxial layer from SCM measurements, as well as the depth concentration distribution of dopant elements (N, Al, P) from SIMS measurements. Measurement methods: SIMS, SCM, TEM Product field: Power devices Analysis purpose: Trace concentration evaluation, shape evaluation, product investigation For more details, please download the materials or contact us.
