Propiedades e características dos materiais

Our semiconductor quartz disks are fabricated from high-purity fused quartz, a material renowned for its exceptional properties. The key characteristics of our quartz disks include:

● High Purity: Containing minimal impurities, our quartz disks prevent contamination of sensitive semiconductor wafers, which is essential for maintaining device integrity and yield.

● Excelente estabilidade térmica: With a low coefficient of thermal expansion, quartz disks can withstand extreme temperature fluctuations without cracking or warping. This makes them ideal for high-temperature processes like annealing, diffusion, and oxidation.

● Chemical Inertness: Quartz is highly resistant to most acids and chemicals used in semiconductor processing, including hydrofluoric acid (HF) and sulfuric acid (H2SO4). This chemical inertness ensures a stable and non-reactive environment for the wafers.

● High Transparency: Fused quartz has high transparency to ultraviolet (UV) light, which is crucial for photolithography and other optical processes.

Our quartz disks are available in a range of sizes and thicknesses, with typical parameters including:

● Purity: >99.995%

● Thermal Expansion Coefficient: ~0.54 x 10−6/°C (at 20-300°C)

● Softening Point: ~1600°C

● Available Diameters: Up to 300mm

Aplicacións na fabricación de semicondutores

High-purity quartz disks are indispensable in several key semiconductor processes. Their specific applications include:

● CVD (Chemical Vapor Deposition): Quartz disks are used as susceptor plates or liners in CVD reactors. Their thermal stability and chemical inertness ensure uniform heating and a contamination-free environment for thin film deposition processes.

● PVD (Physical Vapor Deposition): In PVD processes like sputtering, quartz disks serve as target backings or substrate holders. They can withstand the high kinetic energy of the deposition process while maintaining dimensional stability.

● Oxidation and Diffusion: As a liner for furnaces or as a wafer boat component, quartz disks are integral to high-temperature oxidation and diffusion processes. They prevent metal contamination from the furnace walls from reaching the silicon wafers.

● Recocido: Quartz disks provide a clean and stable surface for thermal annealing, a process used to repair crystal lattice damage and activate dopants in semiconductor devices.
