The coated parts in semiconductor silicon single crystal hot field are generally coated by CVD method, including pyrolytic carbon coating, Silicon Carbide coating and Tantalum Carbide coating, each with different characteristics.

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.

SiC MOSFETs are transistors that offer high power density, improved efficiency, and low failure rates at high temperatures. These advantages of SiC MOSFETs bring numerous benefits to electric vehicles (EVs), including longer driving range, faster charging, and potentially lower cost battery electric vehicles (BEVs). Over the past five years, SiC MOSFETs have been widely used in the power electronics of EVs in vehicles from OEMs such as Tesla and Hyundai. In fact, SiC inverters accounted for 28% of the BEV market in 2023.

When producing large-sized GaN single crystal substrates, HVPE is currently the best choice for commercialization. However, the back carrier concentration of the grown GaN cannot be precisely controlled.

The ultra-high synthesis temperature and the difficulty of achieving dense sintering of SiC ceramics have limited their development. The sintering process is crucial for SiC ceramics.

Semiconductor materials are the materials with electrical conductivity between conductors and insulators at room temperature, which are widely used in fields like integrated circuits, communications, energy and optoelectronics. With development of technology, semiconductor materials have evolved from the first generation to the fourth generation.
