Alumina ceramics are the "workhorse" for manufacturing ceramic components. They exhibit excellent mechanical properties, ultra-high melting points and hardness, corrosion resistance, strong chemical stability, high resistivity, and superior electrical insulation. They are commonly used to fabricate polishing plates, vacuum chucks, ceramic arms, and similar parts.

With the development of the solar photovoltaic industry, diffusion furnaces and LPCVD furnaces are the main equipment for the production of solar cells, which directly affect the efficient performance of solar cells. Based on the comprehensive product performance and usage cost, silicon carbide ceramic materials have more advantages in the field of solar cells than quartz materials. The application of silicon carbide ceramic materials in the photovoltaic industry can greatly help photovoltaic enterprises reduce auxiliary material investment costs, improve product quality and competitiveness. The future trend of silicon carbide ceramic materials in the photovoltaic field is mainly towards higher purity, stronger load-bearing capacity, higher loading capacity, and lower cost.

Diamond, a potential fourth-generation "ultimate semiconductor," is gaining attention in semiconductor substrates due to its exceptional hardness, thermal conductivity, and electrical properties. While its high cost and production challenges limit its use, CVD is the preferred method. Despite doping and large-area crystal challenges, diamond holds promise.

Thin film deposition is vital in chip manufacturing, creating micro devices by depositing films under 1 micron thick via CVD, ALD, or PVD. These processes build semiconductor components through alternating conductive and insulating films.

When you see the third-generation semiconductors, you will surely wonder what the first and second generations were. The "generation" here is classified based on the materials used in semiconductor manufacturing.

The article explains the temperature gradient in a single-crystal furnace. It covers the static and dynamic heat fields during crystal growth, the solid-liquid interface, and the temperature gradient's role in solidification.
