Silicon Carbide (SiC) Wafer Grades for Power Device Fabrication
Silicon carbide wafer grading helps researchers and device manufacturers choose the right SiC substrate for power electronics, Schottky diodes, MOSFETs, JFETs, IGBTs, RF devices, and high-voltage semiconductor applications. Different grades balance crystal quality, defect density, wafer cost, and device performance.
Higher-grade SiC wafers may offer tighter tolerances for micropipe density (MPD), threading screw dislocation (TSD), basal plane dislocation (BPD), resistivity, bow, warp, and surface quality. These specifications are important for improving device yield and reducing manufacturing costs.
| SiC Grade | Strengths | Typical Applications |
|---|---|---|
| Prime Standard | Balanced performance and cost with controlled micropipe density for low-to-medium current devices. | Schottky diodes and junction barrier Schottky devices. |
| Prime Select | More stringent MPD and TSD tolerances for improved device reliability and mid-range current ratings. | PIN diodes, switches, and power devices. |
| Prime Ultra | Very low MPD, TSD, and BPD tolerances with tighter wafer resistivity control for high-current devices. | High-current MOSFETs, JFETs, IGBTs, BJTs, and large-area PIN diodes. |
