Silicon carbide nanomaterials (SiC) are materials with at least one dimension at the nanometer scale (1-100nm). These materials can be zero-, one-, two-, or three-dimensional and have diverse applications.

Silicon carbide ceramics, commonly known as SiC ceramics, are a versatile material with unique properties and a wide range of applications in various industries. The following is a detailed discussion of its material composition, physical properties, specific applications and advantages in semiconductor coating processes, and common problems encountered during processing.

This blog takes "What is the epitaxial process?" as its theme, and provides a detailed analysis from the dimensions of Overview of Epitaxial Processes, Types of Epitaxy, Factors Influencing the Epi Process, Epitaxial Growth Techniques, EPI Growth Modes, and Epitaxy Growth’s Importance.

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.

Etching technology in semiconductor manufacturing often encounters problems such as loading effect, micro-groove effect and charging effect, which affect product quality. Improvement solutions include optimizing plasma density, adjusting reaction gas composition, improving vacuum system efficiency, designing reasonable lithography layout, and selecting appropriate etching mask materials and process conditions.
