Description of 3C-N SiC

The 4-inch 3C-N type silicon carbide (SiC) wafer is characterized by its cubic crystal structure, differing from the hexagonal structure typically seen in 4H-SiC wafers.

In 3C-SiC, silicon and carbon atoms are arranged in a cubic lattice, similar to the diamond structure, giving it unique properties that stand out in certain applications.

One of the major advantages of 3C-SiC is its higher electron mobility and saturation velocity.

Compared to 4H-SiC, 3C-SiC allows for faster electron movement and higher power handling capability, which makes it a promising material for power electronic devices.

This property, combined with the relative ease of manufacturing and lower cost, positions 3C-SiC as a more cost-effective solution in large-scale production.

Moreover, 3C-SiC wafers are particularly suitable for high-efficiency power electronic devices.

The material’s excellent thermal conductivity and stability enable it to perform well in harsh conditions involving high temperatures, pressure, and frequencies.

As a result, 3C-SiC is ideal for use in electric vehicles, solar inverters, and energy management systems, where high efficiency and reliability are critical.

Currently, 3C-SiC devices are primarily built on silicon substrates, though challenges remain due to lattice and thermal expansion coefficient mismatches, which affect performance.

However, the development of bulk 3C-SiC wafers is a growing trend, expected to drive significant advancements in the power electronics industry, particularly for devices in the 600V-1200V voltage range.
