China SiC Cantilever Wafer Handling Manufacturer, Supplier, Factory

This article first introduces the molecular structure and physical properties of TaC, and focuses on the differences and applications of sintered tantalum carbide and CVD tantalum carbide, as well as VeTek Semiconductor's popular TaC coating products.

The four most powerful graphite manufacturers in the world: SGL, Toyo Tanso, Tokai Carbon, Mersen and their corresponding typical graphite and application areas.

Silicon carbide substrates have many defects and cannot be processed directly. A specific single crystal thin film needs to be grown on them through an epitaxial process to make chip wafers. This thin film is the epitaxial layer. Almost all silicon carbide devices are realized on epitaxial materials. High-quality silicon carbide homogeneous epitaxial materials are the basis for the development of silicon carbide devices. The performance of epitaxial materials directly determines the realization of the performance of silicon carbide devices.

In the growth of SiC and AlN single crystals using the physical vapor transport (PVT) method, crucial components such as the crucible, seed holder, and guide ring play a vital role. As depicted in Figure 2 [1], during the PVT process, the seed crystal is positioned in the lower temperature region, while the SiC raw material is exposed to higher temperatures (above 2400 ℃).

Solid silicon carbide has excellent properties such as high temperature stability, high hardness, good abrasion resistance, and good chemical stability, so it has a wide range of applications. The following are some applications of solid silicon carbide:

Electron beam evaporation is a highly efficient and widely used coating method compared to resistance heating, which heats the evaporation material with an electron beam, causing it to vaporize and condense into a thin film.
