Summary: | This SiC single crystal seed includes: a main surface having an offset angle of 2-20º with respect to the {0001} surface; and at least one sub growth surface. The sub growth surface includes an initial facet forming surface which is on the offset upstream side from the main surface, and for which the inclination angle θ with respect to the {0001} surface is, by absolute value, less than 2º in any direction. The initial facet forming surface includes a screw dislocation generation point of origin.
L'invention concerne un germe de monocristal de SiC comprenant : une surface principale ayant un angle de décalage de 2 à 20° par rapport à la surface {1}; et au moins une sous surface de croissance. La sous surface de croissance comprend une surface de formation de facette initiale qui est sur le côté amont de décalage par rapport à la surface principale, et pour laquelle l'angle d'inclinaison θ par rapport à la surface {1} est, en valeur absolue, inférieur à 2º dans une direction quelconque. La surface de formation de facette initiale comprend un point d'origine de génération de dislocation vis.
