Due to the need to improve the performance and the cost limits, new materials, platforms and designs are continually being investigated in the semiconductor industry. In the previous decade, some compound semiconductors, such as gallium arsenide (GaAs) for radio frequency (RF) and silicon carbide (SiC) for power electronics, have succeeded in competing with silicon and have entered the mass market...
