China Epi Susceptor Manufacturers, Suppliers, Factory

Recently, our company announced that the company has successfully developed a 6-inch Gallium Oxide single crystal using the casting method, becoming the first domestic industrialized company to master the 6-inch Gallium Oxide single crystal substrate preparation technology.

An Electrostatic Chuck (ESC) is a device used to hold semiconductor wafers in place during processes such as etching, deposition, or polishing.

Silicon carbide ceramic membranes have significant advantages in the fields of water treatment and industrial separation, and their application scenarios are wide-ranging.

The wafer boats, loaded with a batch of wafers to be processed, are positioned on long cantilevered paddles.

Within the silicon carbide (SiC) industry chain, substrate suppliers hold significant leverage, primarily due to value distribution. SiC substrates account for 47% of the total value, followed by epitaxial layers at 23%, while device design and manufacturing constitute the remaining 30%. This inverted value chain stems from the high technological barriers inherent to substrate and epitaxial layer production. Three major challenges plague SiC substrate growth: stringent growth conditions, slow growth rates, and demanding crystallographic requirements. These complexities contribute to increased processing difficulty, ultimately resulting in low product yields and high costs. Furthermore, the epitaxial layer’s thickness and doping concentration are critical parameters directly impacting the final device performance.
