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”.

In modern electronics, optoelectronics, microelectronics, and information technology fields, semiconductor substrates and epitaxial technologies are indispensable. They provide a solid foundation for manufacturing high-performance, high-reliability semiconductor devices. As technology continues to advance, semiconductor substrates and epitaxial technologies will also progress, bringing new breakthroughs and developments to the future of the semiconductor industry.

As global acceptance of electric vehicles gradually increases, Silicon Carbide (SiC) will encounter novel growth opportunities in the forthcoming decade. It is anticipated that manufacturers of power semiconductors and operators in the automotive industry will participate more actively in the construction of this sector’s value chain.

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.

In the field of single crystal growth, the temperature distribution within the crystal growth furnace plays a critical role. This temperature distribution, commonly referred to as the thermal field, is a vital factor that influences the quality and characteristics of the crystal being grown. The thermal field can be categorized into two types: static and dynamic.

An Electrostatic Chuck (ESC) is a device used to hold semiconductor wafers in place during processes such as etching, deposition, or polishing.
