What is Aluminum Silicon Copper (AlSiCu) Sputtering Target?

Aluminum Silicon Copper (AlSiCu) sputtering targets are high-purity metallic materials used in thin-film deposition processes, primarily for semiconductor, microelectronics, and optical coating applications. These targets consist of an optimized alloy of aluminum (Al), silicon (Si), and copper (Cu), which enhances electrical conductivity, adhesion, and thermal stability in deposited films.

Chemical Properties of AlSiCu Sputtering Targets

  • Chemical Composition: Typically Al (85-98%), Si (0.5-10%), Cu (0.5-5%)
  • Density: ~2.7 g/cm³ (varies based on composition)
  • Melting Point: ~550-660°C
  • Thermal Conductivity: High
  • Electrical Resistivity: Low (improves with Cu doping)
  • Purity: 99.9% – 99.999% (Electronic Grade)
  • CAS Number: 7429-90-5 (Al), 7440-21-3 (Si), 7440-50-8 (Cu)
