Company Profile:
As a leading SiC (Silicon Carbide) epitaxial wafer supplier, ZMSH specialize in the production, processing, and global distribution of high-quality 4H-N-type conductive and MOS-grade epitaxial wafers in 2-inch (50.8mm), 3-inch (76.2mm), 4-inch (100mm), and 6-inch (150mm) diameters, with capabilities extending up to 12-inch (300mm) for future industry demands.
Our product portfolio includes:
· 4H-N-type & 6H-N-type conductive SiC substrates (for power devices)
· High-Purity Semi-Insulating (HPSI) & SEMI-standard wafers (for RF applications)
· 4H/6H-P-type & 3C-N-type SiC wafers (for specialized semiconductor needs)
· Custom doping, thickness, and surface finishes (CMP, epi-ready, etc.)
With advanced CVD epitaxial growth technology, strict quality control (ISO 9001), and full in-house processing capabilities, we serve automotive, power electronics, 5G, and aerospace industries worldwide.

1. Q: What are the key differences between 2-inch, 4-inch and 6-inch SiC epitaxial wafers?
A: The main differences are in production scalability (6" enables higher volume) and cost-per-chip (larger wafers reduce device costs by ~30%).
2. Q: Why choose 4H-SiC over silicon for power devices?
A: 4H-SiC offers 10x higher breakdown voltage and 3x better thermal conductivity than silicon, enabling smaller, more efficient power systems.
