There are six classifications for semiconductors, which are classified by product standard, processing signal type, manufacturing process, usage function, application field, and design method.

Epitaxial wafer process is a critical technique used in semiconductor manufacturing. It involves the growth of a thin layer of crystal material on top of a substrate, which has the same crystal structure and orientation as the substrate. This process creates a high-quality interface between the two materials, allowing for the development of advanced electronic devices.

The history of silicon carbide (SiC) dates back to 1891, when Edward Goodrich Acheson accidentally discovered it while attempting to synthesize artificial diamonds. Acheson heated a mixture of clay (aluminosilicate) and powdered coke (carbon) in an electric furnace. Instead of the expected diamonds, he obtained a bright green crystal adhering to the carbon. This crystal had a hardness second only to diamond, and was thus named carborundum. In 1904, French-Jewish chemist Henri Moissan discovered rare natural silicon carbide minerals while studying meteorite samples from the Diablo Canyon in Arizona, USA. He named these minerals moissanite, and his discovery earned him the 1906 Nobel Prize in Chemistry.

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 single crystal growth furnace is composed of six key systems that work in harmony to ensure efficient and high-quality crystal growth.
