Silicon carbide (SiC) ingot is basically made up of layers of silicon and carbon atoms stacked in different patterns. This stacking variety leads to more than 200 possible crystal structures. That means you can pick the exact type of SiC that fits your specific needs.Now, among all these options, 4H-SiC really stands out. It hits a sweet spot by combining a wide bandgap, high electron mobility, strong breakdown field strength, and excellent heat dissipation. Because it balances these key properties so well, 4H-SiC has become the go-to material for making tough semiconductor devices that need to handle high voltage, high power, high frequencies, and extreme temperatures.
