摘要：A semiconductor device comprises a semiconductor layer of SiC and aninsulating layer thereon for insulating the SiC layer with respect to a metal plateconstituting a gate and connectable to a voltage for creating a conducting surfacechannel at a SiC layer-insulating layer interface, wherein at least a portion of theinsulating layer closest to the interface is made of a crystalline material which is
substantially lattice-matched to SiC and has substantially the same coefficient of thermalexpansion as SiC; and wherein the material has AlN as the only component or as a majorcomponent of an alloy with insulating properties.
