Chemische Eigenschaften
Silicon monoxide (SiO) is another oxide of silicon, used rarely in silicon processing but quite often in thin film, hybrid Ie manufacture. It is useful there because no silicon is available for in situ growth of the dioxide, and it is deposited easily by physical vapor deposition, a process quite similar to the vacuum deposition of aluminum described. Usually the condensed oxide is nonstoichiometric, being a mixture of SiO, Si02, and Si; often, it is designated SiOx .The value of x, which ranges between 1 and 2, is influenced by the deposition conditions.
The SiO source material is prepared by heating Si02 with Si, carbon, and hydrogen, or a hydrocarbon, to reduce the dioxide to the monoxide. Reduction takes place at roughly 1000°C, and SiO is formed in the vapor phase. This temperature is much too low to produce a significant vapor pressure of Si02, so the two oxides may be separated. The monoxide vapor is condensed out and subsequently powdered. This material, which is suitable for evaporation, is available commercially and need not be prepared by the IC manufacturer.
Verwenden
Silicon monoxide (SiO) is a commonly used material for a wide variety of applications with the emphasis on IR multilayer coatings and adhesion promotion. SiO sublimes and should preferably be evaporated from resistance heated boats.
AREAS OF APPLICATION
Multilayer coatings especially for the IR, but also the VIS range
Adhesion promoter (VIS, NIR)
Electronics: dielectric, insulating and protective layers
Design: iridescent coatings, colored metallically reflecting coatings e.g. on sun glasses
Web coating: barrier layers on polymer films
Verwenden
To form thin surface films for protection of alu- minum coatings, optical parts, mirrors, dielectrics, or insulators.
Verwenden
Silicon(II) oxide sputtering target coatings are used for optical applications in reflectors, flood lamps, mirrors, jewelry, and other products. The coatings can reduce reflection in the near infrared range or act as interference layers. It is used in thin-film capacitors, hybrid circuits, semiconductor components and other electronic applications.
Definition
ChEBI: Silicon monoxide is a silicon oxide.
