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.

Both are N-type semiconductors, but what's the difference between arsenic and phosphorus doping in single-crystal silicon? In single-crystal silicon, arsenic (As) and phosphorus (P) are both commonly used N-type dopants (pentavalent elements that provide free electrons). However, due to differences in atomic structure, physical properties, and processing characteristics, their doping effects and application scenarios differ significantly.

With the rapid development of fifth-generation mobile communications (5G), the Internet of Things, and power electronics, electronic components are evolving towards miniaturization, high integration, and high frequency and speed.
