MOCVD is a new vapor phase epitaxial growth technology developed on the basis of vapor phase epitaxial growth (VPE).

Silicon carbide ceramics offer numerous advantages in the optical fiber industry, including high-temperature stability, low thermal expansion coefficient, low loss and damage threshold, mechanical strength, corrosion resistance, good thermal conductivity, and low dielectric constant. These properties make SiC ceramics an ideal material for fiber optic sensors, lasers, and high-power optical fiber applications. As demand in the optical fiber field increases, the application prospects for silicon carbide ceramics will become increasingly prominent.

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.

Gallium Nitride (GaN) epitaxial wafer growth is a complex process, often utilizing a two-step method. This method involves several critical stages, including high-temperature baking, buffer layer growth, recrystallization, and annealing. By meticulously controlling the temperature throughout these stages, the two-step growth method effectively prevents wafer warping caused by lattice mismatch or stress, making it the predominant fabrication method for GaN epitaxial wafers globally.

Silicon carbide (SiC), as an important high-end ceramic material, has excellent properties such as high-temperature resistance, corrosion resistance, wear resistance, high-temperature mechanical strength, and oxidation resistance. These properties make it highly promising for applications in high-tech fields such as semiconductors, nuclear energy, defense, and space technology.

In the semiconductor manufacturing process, wafers form the foundation of chip production. Among these, a special type of wafer, referred to as the Dummy Wafer, plays a pivotal role in ensuring equipment stability and controlling production costs.
