As of this writing, much of the outstanding theoretical promise of SiC electronics highlighted in the
previous section has largely gone unrealized. A brief historical examination quickly shows that serious
shortcomings in SiC semiconductor material manufacturability and quality have greatly hindered the
development of SiC semiconductor electronics. From a simple-minded point of view, SiC electronics
development has very much the general rule of thumb that a solid-state electronic device can
only be as good as the semiconductor material from which it is made.
