Performance limiting micropipe defects in silicon carbide …
Abstract: Reports on the characteristics of a major defect in mass-produced silicon carbide wafers which severely limits the performance of silicon carbide power devices. Micropipe defects originating in 4H- and 6H-SiC substrates were found to cause pre-avalanche reverse-bias point failures in most epitaxially-grown pn junction devices of 1 mm/sup 2/ or larger in area.
Recrystallized silicon carbide tubes, beams, batts and …
RSIC uses highly pure silicon carbide materials. They are produced by evaporation- coagulation and fired under high-temperature 2400℃ to get a highly pure ceramic with porous network structure. This material has an open porosity of approximately 11% to 15%, the grain size of approximately 100 pm, shrinkage behaviour at firing (no shrinkage occurs), and appliions (kiln construction).
