China High Purity SiC wafer boat Manufacturer, Supplier, Factory

VETEK's new semiconductor manufacturing facility has entered the semiconductor-grade cleanroom construction stage. The new site will support the production of CVD SiC coated graphite components, TaC coatings, PyC coatings, Solid SiC parts, and high-purity graphite materials for semiconductor applications.

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.

Silicon carbide (SiC) is a high-precision semiconductor material known for its excellent properties like high temperature resistance, corrosion resistance, and high mechanical strength. It has over 200 crystal structures, with 3C-SiC being the only cubic type, offering superior natural sphericity and densification compared to other types. 3C-SiC stands out for its high electron mobility, making it ideal for MOSFETs in power electronics. Additionally, it shows great potential in nanoelectronics, blue LEDs, and sensors.

On September 5, 2025, a customer from Poland visited a factory under VETEK to learn about our advanced technologies and innovative processes in the production of carbon fiber products.

With the development of the solar photovoltaic industry, diffusion furnaces and LPCVD furnaces are the main equipment for the production of solar cells, which directly affect the efficient performance of solar cells. Based on the comprehensive product performance and usage cost, silicon carbide ceramic materials have more advantages in the field of solar cells than quartz materials. The application of silicon carbide ceramic materials in the photovoltaic industry can greatly help photovoltaic enterprises reduce auxiliary material investment costs, improve product quality and competitiveness. The future trend of silicon carbide ceramic materials in the photovoltaic field is mainly towards higher purity, stronger load-bearing capacity, higher loading capacity, and lower cost.
