The 6H Silicon Carbide (SiC) Square Substrate is manufactured from high-purity 6H-SiC single crystal material and precisely processed into a square shape for advanced semiconductor and electronic applications. As a representative material of the third-generation wide bandgap semiconductors, 6H-SiC offers outstanding performance under high temperature, high voltage, high frequency, and high power working conditions.
With excellent thermal conductivity, mechanical strength, chemical stability, and electrical properties, 6H SiC square substrates are widely used in power devices, RF devices, optoelectronics, laser systems, and R&D laboratories. The substrates can be supplied in polished, semi-polished, or unpolished surface conditions with customized sizes and thicknesses.
Ultra-high hardness (Mohs hardness ≈ 9.2)
High thermal conductivity (~490 W/m·K) for efficient heat dissipation
Wide bandgap (3.0 eV), suitable for extreme environments
High breakdown electric field strength
Excellent chemical resistance and oxidation resistance
High electron mobility for high-frequency performance
Stable crystal structure and long service life

Q1: What is the difference between 6H-SiC and 4H-SiC?
A: 4H-SiC is more commonly used in commercial power devices today due to higher electron mobility, while 6H-SiC is preferred in certain RF, microwave, and special optoelectronic applications.
Q2: Can you supply unpolished 6H-SiC square substrates?
A: Yes, we offer polished, lapped, and unpolished surfaces based on customer requirements.
Q3: Do you support small-size square substrates?
A: Yes, square sizes down to 2×2 mm can be customized.
Q4: Are inspection and test reports available?
A: Yes, we can provide dimensional inspection reports, resistivity test data, and surface roughness reports.
