Sumitomo contends that EpiEra™ epitaxial wafer has achieved an industry-leading 99% defect-free area (DFA). The company says it was able to virtually eliminate surface defects and Basal Plane Dislocations (BPD) for improved quality, stability, and reliability. Sumitomo Electric showcased this new product at International Conference on Silicon Carbide and Related Materials (ICSCRM) 2017 in Washington D.C., on September 17-22, 2017.

SiC Epitaxial Wafer Good for Power Electronics

Such wafers are used in power electronics devices because of their ability withstand high-power operation under extreme temperatures.
