Silicon carbide (SiC) ceramic is a type of advanced ceramic material known for its exceptional properties and wide range of applications. It is composed of silicon (Si) and carbon (C) atoms arranged in a crystal lattice structure, resulting in a hard and strong material with excellent thermal and electrical conductivity.

Chemical Vapor Deposition (CVD) refers to a process technology where multiple gaseous reactants at varied partial pressures undergo a chemical reaction under specific temperature and pressure conditions. The resulting solid substance deposits on the surface of the substrate material, thereby obtaining the desired thin film. In traditional integrated circuit manufacturing processes, the obtained thin film materials are generally compounds such as oxides, nitrides, carbides, or materials like polycrystalline silicon, amorphous silicon, etc.

Silicon material is a solid material with certain semiconductor electrical properties and physical stability, and provides substrate support for the subsequent integrated circuit manufacturing process. It is a key material for silicon-based integrated circuits. More than 95% of semiconductor devices and more than 90% of integrated circuits in the world are made on silicon wafers.

Semiconductor technology has been the backbone of modern civilization, fundamentally transforming the way we live, work, and interact with the world. It has enabled unprecedented advancements in various fields including information technology, energy, telecommunications, and healthcare. From the microprocessors that power our smartphones and computers, to the sensors in medical devices, and the power electronics in renewable energy systems, semiconductors are at the core of nearly every technological innovation of the past century.

Graphite is vital in producing Silicon Carbide (SiC) semiconductors, known for their exceptional thermal and electrical properties. This makes SiC ideal for high-power, high-temperature, and high-frequency applications. In SiC semiconductor manufacturing, graphite is commonly used for crucibles, heaters, and other high-temperature processing components due to its excellent thermal conductivity, chemical stability, and resistance to thermal shock.

According to reports from German media, U.S. chip manufacturer Wolfspeed is pausing its plans to build a semiconductor plant in Germany.
