MOCVD is a new vapor phase epitaxial growth technology developed on the basis of vapor phase epitaxial growth (VPE).

The push for higher power density and efficiency has become a primary driver of innovation across multiple industries, including data centers, renewable energy, consumer electronics, electric vehicles, and autonomous driving technologies. In the realm of wide bandgap (WBG) materials, Gallium Nitride (GaN) and Silicon Carbide (SiC) are currently the two core platforms, viewed as pivotal tools leading power semiconductor innovation. These materials are profoundly transforming the power electronics industry to address the ever-increasing demand for power.

Silicon carbide (SiC) is a material that possesses exceptional thermal, physical and chemical stability, exhibiting properties that go beyond those of conventional materials. Its thermal conductivity is an astonishing 84W/(m·K), which is not only higher than copper but also three times that of silicon. This demonstrates its enormous potential for use in thermal management applications.

When producing large-sized GaN single crystal substrates, HVPE is currently the best choice for commercialization. However, the back carrier concentration of the grown GaN cannot be precisely controlled.

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.
