Fused Quartz Sputtering Target - T 3mm Ø 75mm

Fused Quartz Sputtering Target is a high-purity quartz glass source material optimized for thin-film deposition, offering exceptional chemical stability, low thermal expansion, and precise compositional control. Produced from ultra-clean SiO₂, it enables the formation of defect-free insulating and optical coatings through RF or DC magnetron sputtering. Process enhancements, such as doping with phosphorus or boron, can improve sputtering yield and adhesion while maintaining the dielectric properties critical for microelectronics and photonics. Applications span semiconductor gate oxides, optical interference coatings, and protective dielectric barriers in optoelectronic devices. Specific technologies benefiting include high-flux laser optics where low-stress SiO₂ films are required, and advanced magnetic recording media where cristobalite suppression in the target reduces particulate defects. In research and innovation, these targets enable development of high-purity, low-stress silica films that are integral to next-generation nanophotonic devices and precision optical instruments, reinforcing their importance in both scientific exploration and industrial-scale manufacturing.
