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

Isostatic graphite is a type of graphite with an ultra-fine grain. It is used for applications where the mechanical properties of other fine-grained graphites are inadequate.

SiC substrates are the most crucial component in the silicon carbide industry, accounting for nearly 50% of its value. Without SiC substrates, it is impossible to manufacture SiC devices, making them the essential material foundation.

Silicon material is a solid material with certain semiconductor electrical properties and physical stability, and provides substrate support for the subsequent integrated circuit manufacturing process. It is a key material for silicon-based integrated circuits. More than 95% of semiconductor devices and more than 90% of integrated circuits in the world are made on silicon wafers.

Wide bandgap (WBG) semiconductors such as Silicon Carbide (SiC) and Gallium Nitride (GaN) are expected to play an increasingly important role in power electronic devices. They offer several advantages over traditional Silicon (Si) devices, including higher efficiency, power density, and switching frequency. Ion implantation is the primary method for achieving selective doping in Si devices. However, there are some challenges when applying it to wide bandgap devices. In this article, we will focus on some of these challenges and summarize their potential applications in GaN power devices.

Semiconductors are materials that guide electrical properties between conductors and insulators, with equal probability of loss and gain of electrons in the outermost layer of the atomic nucleus, and are easily made into PN junctions. Such as "silicon (Si)", "germanium (Ge)" and other materials.
