High Purity and Transparency
Quartz discs are made from high-purity silicon dioxide and exhibit exceptional transparency, particularly across the ultraviolet to infrared spectral range. This makes them ideally suited for optical applications.
High-Temperature Resistance
Quartz discs can withstand extremely high temperatures, with a softening point around 1730°C, and can be used continuously at 1100°C, and can tolerate short-term temperatures up to 1450°C. This makes them suitable for high-temperature environments.
Chemical Stability
Quartz discs demonstrate excellent resistance to most chemicals, with the exception of hydrofluoric acid, making them very stable for chemical laboratory and industrial uses.
Low Thermal Expansion Coefficient
Quartz discs have a very low thermal expansion coefficient, which means their dimensions change very little with temperature variations. This is essential for applications requiring precise dimensional control, such as in precision instruments and high-temperature equipment.
Application Scenario
Semiconductor Industry
Quartz discs play a significant role in semiconductor manufacturing, serving as carriers and processing substrates for wafers. They are used in critical process steps such as photolithography, oxidation, diffusion, and chemical vapor deposition, which demand extremely high levels of purity, temperature resistance, and dimensional precision.
In semiconductor manufacturing, quartz discs primarily serve as carriers and substrates for silicon wafers during processing. They are utilized as base materials in crucial process steps like photolithography, oxidation, diffusion, and chemical vapor deposition (CVD). Their high temperature resistance, chemical inertness, and precise dimensional control are essential for ensuring the performance of semiconductor devices.
The optical properties of quartz discs are critical because their applications in the optoelectronics industry require high transparency and broad spectral transmission. These characteristics make quartz discs ideal materials for manufacturing optical lenses, prisms, windows, and other optical components. They are also well-suited for use in laser equipment and optical communication systems.
In LED manufacturing, quartz discs primarily function as high-temperature and chemical-resistant support materials. They provide stable physical support and protection for LED chips during the fabrication process, especially under high-temperature and corrosive environments, ensuring the stability of the production process and the quality of the final products.
