The material of silicon carbide epitaxial layer is silicon carbide, which is usually used to manufacture high-power electronic devices and LEDs. It is widely used in the semiconductor industry due to its excellent thermal stability, mechanical strength and high electrical conductivity.

This article introduces the latest developments in the newly designed PE1O8 hot-wall CVD reactor of the Italian company LPE and its ability to perform uniform 4H-SiC epitaxy on 200mm SiC.

Silicon carbide substrates have many defects and cannot be processed directly. A specific single crystal thin film needs to be grown on them through an epitaxial process to make chip wafers. This thin film is the epitaxial layer. Almost all silicon carbide devices are realized on epitaxial materials. High-quality silicon carbide homogeneous epitaxial materials are the basis for the development of silicon carbide devices. The performance of epitaxial materials directly determines the realization of the performance of silicon carbide devices.

Silicon carbide (SiC) is a high-precision semiconductor material known for its excellent properties like high temperature resistance, corrosion resistance, and high mechanical strength. It has over 200 crystal structures, with 3C-SiC being the only cubic type, offering superior natural sphericity and densification compared to other types. 3C-SiC stands out for its high electron mobility, making it ideal for MOSFETs in power electronics. Additionally, it shows great potential in nanoelectronics, blue LEDs, and sensors.

Electron beam evaporation is a highly efficient and widely used coating method compared to resistance heating, which heats the evaporation material with an electron beam, causing it to vaporize and condense into a thin film.

CVD TAC coating is a process for forming a dense and durable coating on a substrate (graphite). This method involves depositing TaC onto the substrate surface at high temperatures, resulting in a tantalum carbide (TaC) coating with excellent thermal stability and chemical resistance.
