China CVD coating Manufacturers, Suppliers, Factory

As a leading upstream graphite material manufacturer in the semiconductor industry, Semicorex prioritizes the availability, usability, and durability of its materials, setting the standard for excellence in the field.

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.

AlN, as third-generation semiconductor material, is not only an important blue light and ultraviolet light material, but also an important packaging, dielectric isolation and insulation material for electronic devices and integrated circuits, especially suitable for high-temperature and high-power devices. In addition, AlN and GaN have a good thermal match and chemical compatibility, AlN used as GaN epitaxial substrate, can significantly reduce the defect density in GaN devices, improve device performance.

A SiC boat, short for silicon carbide boat, is a high-temperature-resistant accessory used in furnace tubes to carry wafers during high-temperature processing. Due to the outstanding properties of silicon carbide such as resistance to high temperatures, chemical corrosion, and excellent thermal stability, SiC boats are extensively utilized in various thermal treatment processes including diffusion, oxidation, Chemical Vapor Deposition (CVD), and annealing.

Compared with the PVT method, the liquid phase method for growing SiC has the following advantages:

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.
