A “life cycle thinking” approach to assess differences in the energy use of SiC vs. Si power semiconductors
Wide bandgap (WBG) semiconductors have the potential to provide significant improvements in energy efficiency over conventional Silicon (Si) semiconductors. While the potential for energy efficiency gains is widely researched, the relation to the energy use during manufacturing processes remains insufficiently studied. This question is especially relevant for Silicon carbide (SiC) semiconductors, as there are some […]
