A 1.4-kV mesa-type 6H-SiC p+-n diode with an ideal avalanche breakdown and without forward degradation was fabricated. The 6H-SiC substrates were grown on Lely crystals with no micropipes and only minimal defects. The 1.4-kV breakdown voltage, consistent with the ideal breakdown voltage calculated from the thickness and doping concentration of the drift layer was obtained.
