China SiN Substrates Manufacturer, Supplier, Factory

Spatial ALD, spatially isolated atomic layer deposition. The wafer moves between different positions and is exposed to different precursors at each position. The figure below is a comparison between traditional ALD and spatially isolated ALD.

As a leading manufacturer in the SiC industry, Sanan Optoelectronics' related dynamics have received widespread attention in the industry. Recently, Sanan Optoelectronics disclosed a series of latest developments, involving 8-inch transformation, new substrate factory production, establishment of new companies, government subsidies and other aspects.

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.

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.

Vacuum coating includes film material vaporization, vacuum transportation and thin film growth. According to the different film material vaporization methods and transportation processes, vacuum coating can be divided into two categories: PVD and CVD.

With the growing demand for SiC materials in power electronics, optoelectronics and other fields, the development of SiC single crystal growth technology will become a key area of ​​scientific and technological innovation. As the core of SiC single crystal growth equipment, thermal field design will continue to receive extensive attention and in-depth research.
