Specialty graphite is graphite with carbon mass fraction greater than 99.99%, also known as "three high graphite" (high strength, high density, high purity). It is characterized by high strength, high density, high purity, high chemical stability, high thermal and electrical conductivity, high temperature resistance, radiation resistance, strong lubrication and easy processing. Isostatic graphite belongs to specialty graphite.

In order to introduce the SiC coated graphite susceptor, it's important to understand its application. When manufacturing devices, further epitaxial layers are required to be built on some wafer substrates.

The Silicon Carbide (SiC) production process encompasses the preparation of substrate and epitaxy from the materials side, followed by chip design and manufacturing, device packaging, and finally, distribution to downstream application markets. Among these stages, substrate material processing is the most challenging aspect of the SiC industry. SiC substrates are both hard and brittle, making cutting, grinding, and polishing extremely difficult. This increases the likelihood of defects during processing and reduces the yield rate. Currently, major international SiC manufacturers are planning to transition from 6-inch to 8-inch SiC wafers. Overcoming the challenges associated with 8-inch substrates has become a critical benchmark for the SiC industry. This article will introduce the key parameters of SiC substrates.

This article delves into the usage and future trajectory of silicon carbide (SiC) boats in relation to quartz boats within the semiconductor industry, specifically focusing on their applications in solar cell manufacturing.

Silicon carbide (SiC) crystal growth furnaces are the cornerstone of SiC wafer production. While sharing similarities with traditional silicon crystal growth furnaces, SiC furnaces face unique challenges due to the material’s extreme growth conditions and complex defect formation mechanisms. These challenges can be broadly categorized into two areas: crystal growth and epitaxial growth.

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