As a third-generation semiconductor material, Gallium Nitride is often compared with Silicon Carbide. Gallium Nitride still demonstrates its superiority with its large bandgap, high breakdown voltage, high thermal conductivity, high saturated electron drift velocity and strong radiation resistance. But it is undeniable that, like Silicon Carbide, Gallium Nitride also has various technical difficulties.

In semiconductor manufacturing, the precision and stability of the etching process are paramount. One critical factor in achieving high-quality etching is ensuring that wafers are perfectly flat on the tray during the process. Any deviation can lead to uneven ion bombardment, causing undesirable angles and variations in etching rates. To address these challenges, engineers have developed Electrostatic Chucks (ESCs), which have significantly improved etching quality and stability. This article delves into the design and functionality of ESCs, focusing on one key aspect: the electrostatic principles behind wafer adhesion.

Silicon carbide (SiC) is a compound formed by covalent bonds between silicon and carbon atoms, known for its excellent wear resistance, thermal shock resistance, corrosion resistance, and high thermal conductivity.

Silicon carbide (SiC) is an inorganic substance. The amount of naturally occurring silicon carbide is very small. It is a rare mineral and is called moissanite. Silicon carbide used in industrial production is mostly artificially synthesized.

Chemical Vapor Deposition (CVD) is a versatile technique for producing high-quality coatings with various applications in industries such as aerospace, electronics, and materials science. CVD-SiC coatings are known for their exceptional properties, including high temperature resistance, mechanical strength, and excellent corrosion resistance.

In the process of silicon wafer manufacturing, after the crystal rod is cut into silicon wafers, it will need to be polished and cleaned to obtain a single crystal silicon wafer like a mirror.
