Silicon carbide (SiC) power devices are semiconductor devices made of silicon carbide materials, mainly used in high-frequency, high-temperature, high-voltage and high-power electronic applications. Compared with traditional silicon (Si)-based power devices, silicon carbide power devices have higher bandgap width, higher critical breakdown electric field, higher thermal conductivity and higher saturated electron drift velocity, which makes them have great development potential and application value in the field of power electronics.

The current third-generation semiconductors are primarily based on Silicon Carbide, with substrates accounting for 47% of device costs, and epitaxy accounting for 23%, totaling approximately 70% and forming the most crucial part of the SiC device manufacturing industry.

The growth of GaN epitaxy on GaN substrate presents a unique challenge, despite the material’s superior properties when compared to silicon. GaN epitaxy offers significant advantages in terms of band gap width, thermal conductivity, and breakdown electric field over silicon-based materials. This makes the adoption of GaN as the backbone for the third generation of semiconductors, which provide enhanced cooling, lower conduction loss, and improved performance under high temperatures and frequencies, a promising and crucial advancement for the photonic and micro-electronic industries.

When cleaning wafers, ultrasonic cleaning and megasonic cleaning are commonly used to remove particles from the wafer surface.

High-Purity Silicon Carbide Powder features exceptional wide bandgap characteristics, which make it an ideal material for manufacturing high-frequency, high-power electronic devices.

In the semiconductor manufacturing process, wafers form the foundation of chip production. Among these, a special type of wafer, referred to as the Dummy Wafer, plays a pivotal role in ensuring equipment stability and controlling production costs.
