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

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.

Silicon carbide has a large number of applications in emerging industries and traditional industries. At present, the global semiconductor market has exceeded 100 billion yuan. It is expected that by 2025, the global sales of semiconductor manufacturing materials will reach 39.5 billion US dollars, of which the silicon carbide semiconductor market is expected to reach a market size of 2.5 billion US dollars in 2025. At the same time, silicon carbide is still the material with the best application performance in traditional ceramics, refractory, high temperature, grinding and other fields.

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.

Tantalum carbide coating is an important high-strength, corrosion-resistant and chemically stable high-temperature structural material with a melting point of up to 4273 °C, one of the several compounds with the highest temperature resistance. It has excellent high-temperature mechanical properties, resistance to high-speed airflow scouring, ablation resistance, and good chemical and mechanical compatibility with graphite and carbon/carbon composites. Therefore, in the epitaxial process of GaN LEDs and SiC power devices such as MOCVD, TaC coating has excellent acid and alkali resistance to H2, HCl, NH3, which can completely protect the graphite substrate material and purify the growth environment.

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.
