Abstract (en)

[origin: WO9909598A1] The invention concerns a semiconductor structure (HS) comprising at least an alpha silicon carbide zone (3, 10, 11) and an electrical insulation zone (13a), consisting for example of an oxide coating, between which is located an interface (20). The selection of an alpha silicon carbide polytype, whereof the forbidden band is smaller than that of H6 silicon carbide polytype, for at least one zone close to the interface, results in high mobility of charge carriers in said zone.
