Silane is an indispensable gas for new semiconductor materials
Another application of silanes is amorphous semiconductors, amorphous silicon. Compared to monocrystalline semiconductor materials, amorphous silicon tends to form very thin (about 10nm thick) large devices. The base can be glass, stainless steel or even plastic, and the surface can be flat or curved, so it can be made into a variety of devices with excellent performance.
Silane has become the main special gas used in semiconductor microelectronic processes, and is used to prepare a variety of microelectronic films such as single crystal thin films, microcrystals, polycrystals, silicon oxides, silicon nitrides, metal silicides, etc. The microelectronic applications of silanes are still being developed: cryogenic elongation, selective elongation, and heterogeneous elongation. It is used not only in silicon devices and silicon integrated circuits, but also in compound semiconductor devices (arsenic, silicon carbide, etc.). It is also used in the preparation of superlattice quantum trap materials. It can be said that silane is the production line of almost all modern advanced integrated circuits. The purity of silane is closely related to the performance and yield of the equipment, and more advanced equipment requires c.
The application of silanes as silica gel films and coatings has expanded from the traditional microelectronics industry to the steel, mechanical, chemical, and optical fields. Silicone coating can increase the high-temperature oxidation resistance of ordinary steel to more than 100,000 times, and can also greatly improve the high-temperature chemical stability of other metals, significantly improve the corrosion resistance of internal combustion engine blades, greatly improve the bonding strength between various materials and parts, prolong the service life of automobile engine parts, and change the reflection and transmittance of glass, so as to achieve significant energy-saving decorative effects. In the production process of float glass, the surface of the glass is only coated with silane, which has strong adhesion and fades under long-term sunlightLarge-area polycrystalline silicon cells are coated with silicon nitride. (BSNSSC) has reached 157% high efficiency. With silane vapor deposition technology, the application of various silicon-containing films in high-tech is still increasing.
Another potential application of silanes is the manufacture of high-performance ceramic engine components, especially silane silicides (Si3N444), SiCs, etc. Micronized technology is getting more and more attention. The United States, Japan, and other countries are spending hundreds of millions of dollars to develop high-temperature, high-strength, and chemically stable silicon, silicon nitride, and silicon carbide powders to make ceramics. The micropowder prepared by silane gas reaction has the highest purity and fine and uniform particle size, which can greatly improve the performance of ceramic parts. It is widely used in the practicality of automotive engine valves and turbocharger rotors, and the commercialization of high-speed bearings and high-performance tools. The internal combustion engine can make the operating temperature reach 1400 °C, which greatly improves the efficiency of the heat engine. Suitable for all kinds of fuels, prolong service life. **Protective layer tiles can also be used as:
