Practical Design of 4H-SiC Superjunction Devices in …

In the ideal case, superjunction (SJ) drift regions theoretically exhibit a linear relationship between specific-on resistance Ron,sp and blocking voltage VBR, but this requires perfect charge balance between the alternating n and p pillars. If any degree of ialance exists, the relationship becomes quadratic, similar to a conventional drift region, although with somewhat improved performance.
