In the process of growing silicon carbide (SiC) crystals via the Physical Vapor Transport (PVT) method, the extreme high temperature of 2000–2500 °C is a “double-edged sword” — while it drives the sublimation and transport of source materials, it also dramatically intensifies impurity release from all materials within the thermal field system, especially trace metallic elements contained in conventional graphite hot-zone components. Once these impurities enter the growth interface, they will directly damage the core quality of the crystal. This is the fundamental reason why tantalum carbide (TaC) coatings have become a “mandatory option” rather than an “optional choice” for PVT crystal growth.

This article describes the physical parameters and product characteristics of VeTek Semiconductor's Porous Graphite, as well as its specific applications in semiconductor processing.

This article introduces the product characteristics of TaC coating, the specific process of preparing TaC coating products using CVD technology, introduces Veteksemicon's most popular TaC coating, and briefly analyzes the reasons for choosing Veteksemicon.

As the 8-inch silicon carbide (SiC) process matures, manufacturers are accelerating the shift from 6-inch to 8-inch. Recently, ON Semiconductor and Resonac announced updates on 8-inch SiC production.

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.
