Introducing CO₂ into the dicing water during wafer cutting is an effective process measure to suppress static charge buildup and lower contamination risk, thereby improving dicing yield and long-term chip reliability.

Semiconductor materials can be classified into three generations in chronological order. The first generation consists of common elemental materials such as germanium and silicon, which are characterized by convenient switching and are generally used in integrated circuits. The second-generation compound semiconductors such as gallium arsenide and indium phosphide are mainly used in luminescent and communication materials.

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.

Silicon carbide (SiC) crystal growth furnaces play a vital role in producing high-performance Sic wafers for next-generation semiconductor devices. However, the process of growing high-quality SiC crystals presents significant challenges. From managing extreme thermal gradients to reducing crystal defects, ensuring uniform growth, and controlling production costs, each step requires advanced engineering solutions. This article will analyze the technical challenges of SIC crystal growth furnaces from multiple perspectives.

In the preparation of high-quality and high-yield silicon carbide substrates, the core requires precise control of production temperature by good thermal field materials. Currently, the thermal field crucible kits mainly used are high-purity graphite structural components, whose functions are to heat molten carbon powder and silicon powder as well as to maintain heat.

Silicon wafer CMP (Chemical Mechanical Planarization) polishing slurry is a critical component in the semiconductor manufacturing process. It plays a pivotal role in ensuring that silicon wafers—used to create integrated circuits (ICs) and microchips—are polished to the exact level of smoothness required for the next stages of production
