It has become an irreversible trend to incorporate third-generation semiconductor materials such as silicon carbide (SiC) into power devices and modules for electric vehicles (EV). And Taiwan III-V semiconductor suppliers can leverage the manufacturing prowess of system device makers to deepen related applications, but will face three stages of challenges in this regard, according to an expert at Electronic and Optoelectronic System Research Laboratories (EOSRL) under the government-funded Industrial Technology Research Institute (ITRI).
