Silicon Carbide (SiC) Wafer Grading

Our grading structure allows power device designers to more
confidently pinpoint the Silicon Carbide wafers that optimizes the performance and cost of their next generation device design. This SiC substrate grading structure sets a higher standard for specifying tolerances. At the highest quality tier, materials feature defect densities as low as MPD ≤ 0.1 cm-2,
TSD ≤ 500 cm-2 and BPD ≤ 1,000 cm-2.

Grades Strengths Applications
Prime Standard Guaranteed MPD tolerances. Balances performance and cost for electronic components with low to medium current ratings. Schottky and junction barrier
Schottky diodes
Prime Select More stringent tolerances for MPD current ratings and TSD.
Allows for manufacturing with mid-range current ratings.
Pin Diodes and Switches
Prime Ultra Extremely low MPD, TSD and BPD tolerances and tightened
wafer resistivity. Ensures product quality and improves cost
efficiency in manufacturing high current devices.
High current and voltage
and pin diodes with large die
