Silicon wafer surface polishing is a crucial process in semiconductor manufacturing. Its primary goal is to achieve extremely high standards of surface flatness and roughness by removing micro-defects, layers of stress damage, and contamination from impurities such as metal ions.

Silicon carbide (SiC) is a compound formed by covalent bonds between silicon and carbon atoms, known for its excellent wear resistance, thermal shock resistance, corrosion resistance, and high thermal conductivity.

The three primary methods used in monocrystalline silicon manufacturing are the Czochralski (CZ) method, the Kyropoulos method, and the Float Zone (FZ) method.

The four main molding methods for graphite molding are: extrusion molding, molding, vibratory molding and isostatic molding. Most of the common carbon/graphite materials on the market are molded by hot extrusion and molding (cold or hot), and isostatic molding is a method with leading molding performance. Vibration molding is generally used to manufacture medium and coarse structural graphite, particle size between 0.5-2mm particle size, generally dominated by di-roasted graphitized products, density between 1.55-1.75kg/m³, coarser particles, rougher surface, can not be used for precision machining. It is mainly used in chemical industry and metal smelting.

​In the realms of semiconductor technology and microelectronics, the concepts of substrates and epitaxy hold significant importance. They play critical roles in the manufacturing process of semiconductor devices. This article will delve into the differences between semiconductor substrates and epitaxy, covering their definitions, functions, material structures, and application areas.

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