SiC MOSFETs are transistors that offer high power density, improved efficiency, and low failure rates at high temperatures. These advantages of SiC MOSFETs bring numerous benefits to electric vehicles (EVs), including longer driving range, faster charging, and potentially lower cost battery electric vehicles (BEVs). Over the past five years, SiC MOSFETs have been widely used in the power electronics of EVs in vehicles from OEMs such as Tesla and Hyundai. In fact, SiC inverters accounted for 28% of the BEV market in 2023.

The surface of the gas distribution plate features hundreds or even thousands of tiny, precisely arranged holes, resembling a finely woven neural network.

A Dummy Wafer is a specialized wafer utilized primarily to fill machine equipment during the wafer manufacturing process.

Within the silicon carbide (SiC) industry chain, substrate suppliers hold significant leverage, primarily due to value distribution. SiC substrates account for 47% of the total value, followed by epitaxial layers at 23%, while device design and manufacturing constitute the remaining 30%. This inverted value chain stems from the high technological barriers inherent to substrate and epitaxial layer production. Three major challenges plague SiC substrate growth: stringent growth conditions, slow growth rates, and demanding crystallographic requirements. These complexities contribute to increased processing difficulty, ultimately resulting in low product yields and high costs. Furthermore, the epitaxial layer’s thickness and doping concentration are critical parameters directly impacting the final device performance.

Heat treatment is one of the essential and important processes in the semiconductor process. Thermal process is the process of applying thermal energy to a wafer by placing it in an environment filled with a specific gas, including oxidation/diffusion/annealing, etc.
