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.

SiC ceramic is a ceramic material produced by the reaction of silicon (Si) and carbon (C) elements, featuring extremely high hardness, heat resistance and chemical stability

The article analyzes the material properties of semiconductor substrate wafers such as silicon, GaAs, SiC and GaN

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.

Wafer CMP polishing slurry is a specially formulated liquid material used in the CMP process of semiconductor manufacturing. It consists of water, chemical etchants, abrasives, and surfactants, enabling both chemical etching and mechanical polishing.

When you see the third-generation semiconductors, you will surely wonder what the first and second generations were. The "generation" here is classified based on the materials used in semiconductor manufacturing.
