Oxidation induced stacking fault
WebJan 4, 2024 · Stacking faults (SFs) generated by thermal oxidation of a 4H-SiC epilayer were investigated using photoluminescence (PL) imaging/mapping and transmission electron … Webon bipolar transistors has been studied. Through the analysis of process flow, oxidation induced stacking faults were indicated as a possible root cause of the yield loss. The identification of the oxidation induced stacking fault mechanism and understanding of its process dependency are very critical to improve the yield and obtain fast ramp-up.
