6inch SiC Epitaxial Wafer Diameter 150mm N type P type for 5G Communication
As a core material for silicon carbide (SiC) power device manufacturing, the 6-inch 4H-SiC epitaxial wafer is based on a 4H-N-type SiC substrate, grown using chemical vapor deposition (CVD) to achieve high uniformity, low defect density, and exceptional electrical performance. Its technical advantages include:
· Crystal Structure: (0001) silicon-face orientation with a 4° offcut to optimize lattice matching and minimize micropipe/stacking fault defects.
· Electrical Performance: N-type doping concentration precisely controlled between 2×10¹⁴–2×10¹⁹ cm⁻³ (±14% tolerance), achieving resistivity adjustable from 0.015–0.15 Ω·cm via in-situ doping technology.
· Defect Control: Surface defect density <25 cm⁻² (TSD/TED), triangular defect density <0.5 cm⁻², ensured by magnetic-field-assisted growth and real-time monitoring.
Leveraging domestically developed CVD equipment clusters, ZMSH achieves full-process control from substrate processing to epitaxial growth, supporting rapid small-batch trials (minimum 50 wafers) and customized solutions for applications in new energy vehicles, photovoltaic inverters, and 5G base stations.
