Common thin films are mainly divided into three categories: semiconductor thin films, dielectric thin films, and metal/metal compound thin films.

Graphite products are key and indispensable components in the semiconductor manufacturing process, including isostatic graphite, porous graphite, felt, etc.

Semiconductor equipment consists of chambers and chambers, and most ceramics are used in chambers closer to the wafers. Ceramic parts, important components widely used in the cavities of core equipment, are semiconductor equipment components manufactured through precision processing using advanced ceramic materials such as alumina ceramics, aluminum nitride ceramics, and silicon carbide ceramics.

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.

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.
