China Silicon Carbide Robot Arm For Wafer Handling Manufacturers, Suppliers, Factory

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

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.

The silicon carbide industry involves a chain of processes that include substrate creation, epitaxial growth, device design, device manufacturing, packaging, and testing. In general, silicon carbide is created as ingots, which are then sliced, ground, and polished to produce a silicon carbide substrate.

At first glance, quartz (SiO2) material looks very similar to glass, but what is special is that ordinary glass is composed of many components (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.), while quartz only contains SiO2, and its microstructure is a simple network composed of silicon dioxide tetrahedral structural units.

In November 2023, Semicorex released 850V GaN-on-Si epitaxial products for high-voltage, high-current HEMT power device applications. Compared to other substrates for HMET power devices, GaN-on-Si enables larger wafer sizes and more diversified applications, and it can also be quickly introduced into the mainstream silicon chip process in fabs, which is a unique advantage for improving the yield of power devices.

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.
