In semiconductor high-temperature processes, the handling, supporting, and thermal treatment of wafers rely on a special supporting component—the wafer boat. As process temperatures rise and cleanliness and particle control requirements increase, traditional quartz wafer boats gradually reveal issues such as short service life, high deformation rates, and poor corrosion resistance.

In PECVD production, many coating and deposition problems do not start with plasma power or gas chemistry. They start with the carrier that holds the wafers.

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.

The core material of PECVD graphite boat is high-purity isotropic graphite material (purity is usually ≥99.999%), which has excellent electrical conductivity, thermal conductivity and density. Compared with ordinary graphite boats, PECVD graphite boats have many physical and chemical property advantages and are mainly used in the semiconductor and photovoltaic industries, especially in PECVD and CVD processes.

The main difference between epitaxy and atomic layer deposition (ALD) lies in their film growth mechanisms and operating conditions. Epitaxy refers to the process of growing a crystalline thin film on a crystalline substrate with a specific orientation relationship, maintaining the same or similar crystal structure. In contrast, ALD is a deposition technique that involves exposing a substrate to different chemical precursors in sequence to form a thin film one atomic layer at a time.
