China RTA SiC coating Manufacturers, Suppliers, Factory

The Silicon Carbide (SiC) production process encompasses the preparation of substrate and epitaxy from the materials side, followed by chip design and manufacturing, device packaging, and finally, distribution to downstream application markets. Among these stages, substrate material processing is the most challenging aspect of the SiC industry. SiC substrates are both hard and brittle, making cutting, grinding, and polishing extremely difficult. This increases the likelihood of defects during processing and reduces the yield rate. Currently, major international SiC manufacturers are planning to transition from 6-inch to 8-inch SiC wafers. Overcoming the challenges associated with 8-inch substrates has become a critical benchmark for the SiC industry. This article will introduce the key parameters of SiC substrates.

Wafers are essential raw materials for integrated circuits, power devices, and semiconductor discrete devices. Over 90% of integrated circuits are manufactured using high-purity, high-quality wafers. The quality and supply capacity of these wafers within the industry are directly linked to the overall performance and competitiveness of integrated circuits. In this discussion, we will introduce the wafer manufacturing process in detail.

Etching is a critical step in chip manufacturing, used to create minute circuit structures on silicon wafers.

The tray (base) that supports SiC wafers, also known as a "susceptor," is a core component of semiconductor manufacturing equipment. And what exactly is this susceptor that carries the wafers?

High-purity quartz possesses remarkable physical and chemical properties. Its inherent crystal structure, shape, and lattice variations contribute to exceptional characteristics such as high-temperature resistance, corrosion resistance, abrasion resistance, low thermal expansion coefficient, high insulation, piezoelectric effects, resonant effects, and unique optical properties. These attributes make it an irreplaceable foundational material for the development of strategic and pillar industries.

Silicon carbide (SiC) is a compound formed by covalent bonds between silicon and carbon atoms, known for its excellent wear resistance, thermal shock resistance, corrosion resistance, and high thermal conductivity.
