Every country is aware of the importance of chips and is now accelerating the construction of its own chip manufacturing supply chain ecosystem to prevent another chip shortage problem. But the advanced foundries without next-gen chip designers would be the same as “Fabs without Chips”.

Chemical Vapor Deposition (CVD) is a versatile technique for producing high-quality coatings with various applications in industries such as aerospace, electronics, and materials science. CVD-SiC coatings are known for their exceptional properties, including high temperature resistance, mechanical strength, and excellent corrosion resistance.

Chemical Vapor Deposition (CVD) refers to a process technology where multiple gaseous reactants at varied partial pressures undergo a chemical reaction under specific temperature and pressure conditions. The resulting solid substance deposits on the surface of the substrate material, thereby obtaining the desired thin film. In traditional integrated circuit manufacturing processes, the obtained thin film materials are generally compounds such as oxides, nitrides, carbides, or materials like polycrystalline silicon, amorphous silicon, etc.

Currently, many semiconductor devices employ mesa device structures, which are predominantly created through two types of etching: wet etching and dry etching. While the simple and rapid wet etching plays a significant role in semiconductor device fabrication, it has inherent drawbacks such as isotropic etching and poor uniformity, which result in limited control when transferring small-sized patterns. Dry etching, however, with its high anisotropy, good uniformity, and repeatability, has become prominent in semiconductor device fabrication processes. The term “dry etching” broadly refers to any non-wet etching technology used for removing surface materials and transferring micro and nano patterns, including laser etching, plasma etching, and chemical vapor etching. The dry etching discussed in this text specifically pertains to the narrow application of processes using plasma discharge—either physical or chemical—to modify material surfaces.

This paper provides a comprehensive overview of the various manufacturing techniques employed to produce dense SiC ceramics, highlighting their unique characteristics and applications.

Silicon carbide (SiC), as an important high-end ceramic material, has excellent properties such as high-temperature resistance, corrosion resistance, wear resistance, high-temperature mechanical strength, and oxidation resistance. These properties make it highly promising for applications in high-tech fields such as semiconductors, nuclear energy, defense, and space technology.
