Technical Data Sheet

Description

Silicon is a metalloid and carries the typical properties of both metals and nonmetals. It is extremely inert and insoluble in water and acids. However, it can be dissolved into silicates by hot alkaline lyes. Pure silicon forms dark gray, metallic, shiny crystals. Silicon also has excellent thermal conductivity, which – in pure silicon – is accompanied by extremely low electrical conductivity. When alloyed with aluminium, it enhances strength and reduces weight.

High purity evaporation materials play a huge role in deposition processes to ensure high quality deposited film. Stanford Advanced Materials (SAM) specializes in producing up to 99.999% purity silicon evaporation materials using quality assurance processes to guarantee product reliability.

Applications

1. Solar Cell Manufacturing: N-type Silicon Evaporation Materials are frequently used in the production of solar cells, particularly in thin-film solar cells. They allow for the deposition of thin, uniform layers of silicon on substrates, which convert sunlight into electricity. Using N-type silicon in solar cells can enhance their efficiency and performance.

2. Semiconductor Manufacturing: Silicon is the fundamental material in the semiconductor industry. N-type Silicon Evaporation Materials are used to deposit silicon layers on wafers during the manufacturing process of transistors, integrated circuits, and other semiconductor devices. These materials enable precise control over the thickness and uniformity of the silicon layers, crucial for the performance of the final devices.

3. Optical Coatings: Silicon evaporation materials can also be used to deposit thin films on optical components, such as mirrors, lenses, and filters. These coatings can enhance the reflectivity, transmittance, or absorption properties of the optical components, improving their performance in various applications, including lasers, spectroscopy, and imaging systems.

4. Thin-Film Transistors (TFTs): N-type Silicon Evaporation Materials are essential in producing thin-film transistors, which are used in flat-panel displays such as LCDs and OLEDs. The silicon layers deposited using these materials serve as the semiconducting channel in the transistors, controlling the flow of electric current and enabling the display of images.

5. Microelectronics and Nanoelectronics: In the field of microelectronics and nanoelectronics, N-type Silicon Evaporation Materials are used to create nanoscale structures and devices. These materials enable the precise deposition of silicon on substrates, enabling the development of miniaturized electronic components and systems with improved performance.
