摘要：
Based on a newly proposed edge termination technique on silicon carbide (SiC) device named aperture density modulation (ADM), this article investigates the optimization strategy of a family of termination structures derived from it. Using both analytical modeling and numerical simulation, this article demonstrates the capability of achieving 15-kV breakdown voltage with a termination length of 160-240 mu in theory. Besides, the fabrication feasibility with profile customizability is also demonstrated in experiments while still keeping a low process cost.
