Silicon is the second most abundant element on Earth after oxygen. Most silicon is found in soil, rocks, natural water, trees, and plants.

The third-generation wide bandgap semiconductor materials, such as Gallium Nitride (GaN) and Silicon Carbide (SiC), are renowned for their exceptional optoelectronic conversion and microwave signal transmission capabilities. These materials meet the demanding requirements of high-frequency, high-temperature, high-power, and radiation-resistant electronic devices. Therefore, they have vast application prospects in new-generation mobile communications, new energy vehicles, smart grids, and LED technologies. The comprehensive development of the third-generation semiconductor industry urgently requires breakthroughs in key core technologies, continual advancement in device design and innovation, and a resolution to import dependencies.

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.

Gallium Nitride (GaN) is an important material in semiconductor technology, known for its exceptional electronic and optical properties. GaN, as a wide-bandgap semiconductor, has a bandgap energy of approximately 3.4 eV, making it ideal for high-power and high-frequency applications.

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