6H Silicon Carbide Wafers 

6H silicon carbide (6H-SiC) wafers are wide-bandgap semiconductor substrates used in power electronics, RF devices, photonics, high-temperature sensors, Raman spectroscopy, and X-ray diffraction (XRD). Their excellent thermal conductivity, high breakdown voltage, and chemical stability make them an ideal material for advanced semiconductor research, transparent optical components, and harsh-environment applications. UniversityWafer supplies high-quality 6H-SiC wafers in multiple diameters, thicknesses, orientations, and grades to meet research and production requirements.

What Applications Require 6H Silicon Carbide Substrates?

6H silicon carbide wafers, also called 6H-SiC substrates, are used in research applications that require a wide bandgap material with high thermal stability, strong mechanical hardness, and resistance to harsh environments. Transparent 6H-SiC is especially useful for optical materials research, Raman measurements, XRD calibration, photonics, and semiconductor device development.

Why Researchers Use 6H-SiC Wafers

  • Wide bandgap material for high-temperature and high-voltage applications
  • Excellent thermal conductivity for power and RF device research
  • Strong chemical and mechanical stability in harsh environments
  • Useful for Raman, XRD, optics, and photonics experiments
  • Available as transparent silicon carbide wafers for optical research
  • Can be used for epitaxial graphene and advanced materials studies

Common 6H Silicon Carbide Applications

6H-SiC substrates are used in power electronics, MOSFET research, Schottky diodes, RF and microwave devices, high-temperature sensors, UV photodetectors, and optoelectronic components. Their durability makes them useful for demanding semiconductor, aerospace, automotive, and laboratory environments.

6H-SiC for Raman and XRD Calibration

Researchers often request 6H silicon carbide pieces, scrap, or reject wafers for Raman measurements and XRD analysis. These materials can be useful for calibration, reference testing, and comparison studies when full prime-grade wafers are not required.

6H-SiC vs. 4H-SiC

Both 6H-SiC and 4H-SiC are hexagonal silicon carbide polytypes. 4H-SiC is commonly selected for many modern high-power devices because of its electrical performance and commercial availability. 6H-SiC remains important for research, optical testing, Raman calibration, XRD studies, epitaxial graphene growth, and specialty semiconductor applications.

Available 6H-SiC Wafer Options

UniversityWafer can quote 3 inch and 4 inch 6H silicon carbide wafers, including common thicknesses such as 500 µm and 1 mm, when available. Transparent, semi-insulating, conductive, prime-grade, mechanical-grade, scrap, and reject SiC pieces may be available depending on inventory.
