Silicon Carbide (SiC) has emerged as a key material in the field of semiconductor technology, offering exceptional properties that make it highly desirable for various electronic and optoelectronic applications. The production of high-quality SiC single crystals is crucial for advancing the capabilities of devices such as power electronics, LEDs, and high-frequency devices. In this article, we delve into the significance of porous graphite in the Physical Vapor Transport (PVT) method for 4H-SiC single crystal growth.

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.

Recently, the semiconductor industry has continued to pay increasing attention to Gallium Nitride (GaN) technology. Due to its excellent electronic properties, Gallium Nitride devices have important applications in many high-tech fields:

In the semiconductor industry, epitaxial layers play a crucial role by forming specific single-crystal thin films atop a wafer substrate, collectively known as epitaxial wafers. Particularly, silicon carbide (SiC) epitaxial layers grown on conductive SiC substrates produce homogenous SiC epitaxial wafers, which are instrumental in the fabrication of power devices such as Schottky diodes, MOSFETs, and IGBTs, with 4H-SiC substrates being the most widely utilized.

The history of silicon carbide (SiC) dates back to 1891, when Edward Goodrich Acheson accidentally discovered it while attempting to synthesize artificial diamonds. Acheson heated a mixture of clay (aluminosilicate) and powdered coke (carbon) in an electric furnace. Instead of the expected diamonds, he obtained a bright green crystal adhering to the carbon. This crystal had a hardness second only to diamond, and was thus named carborundum. In 1904, French-Jewish chemist Henri Moissan discovered rare natural silicon carbide minerals while studying meteorite samples from the Diablo Canyon in Arizona, USA. He named these minerals moissanite, and his discovery earned him the 1906 Nobel Prize in Chemistry.
