SiO2 (Silicon Dioxide) is a widely used evaporation material in thin-film deposition processes, particularly in the production of optical coatings, dielectric layers, and semiconductor devices. It is commonly employed in thermal and electron-beam evaporation methods due to its high melting point and stable properties.

Key Applications:

• Optical Coatings: SiO2 is extensively used for anti-reflective coatings (AR), high-reflective coatings (HR), and protective layers in various optical components such as lenses, mirrors, and windows.
• Dielectric Layers: It serves as an insulator in semiconductor devices and microelectronics, providing an effective dielectric barrier in integrated circuits.
• Protective Coatings: SiO2 thin films are used as protective coatings for preventing corrosion, wear, and chemical damage on various surfaces.
• Photovoltaic Devices: Silicon dioxide is used in solar cells as a passivation layer, improving efficiency by reducing recombination of charge carriers.
• Waveguides: SiO2 is employed in optical waveguides and fiber optics due to its low optical absorption and high transparency in a wide wavelength range.

Features:

• High Transparency: SiO2 is transparent across a wide spectral range, from UV to IR, making it ideal for optical applications.
• Excellent Insulating Properties: With high dielectric strength and low electrical conductivity, SiO2 is a perfect insulator for microelectronics and semiconductor applications.
• High Melting Point: SiO2 has a melting point of approximately 1,713°C, making it suitable for high-temperature deposition processes.
• Chemical Stability: SiO2 is highly resistant to most acids, bases, and solvents, offering long-lasting protective coatings.
• Mechanical Strength: It provides excellent hardness and durability, ensuring the stability and longevity of thin films.
