  • GaAs (Gallium Arsenide) Wafers

    As a leading GaAs substrate supplier, PAM-XIAMEN manufactures Epi-ready GaAs(Gallium Arsenide) Wafer Substrate including semi-conducting n type, semi-conductor undoped and p type with prime grade and dummy grade. The GaAs substrate resistivity depends on dopants, Si doped or Zn doped is (0.001~0.009) ohm.cm, undoped one is >=1E7 ohm.cm. The GaAs wafer crystal orientation should be (100) and (111). For (100) orientation, it can be 2°/6°/15° off. The EPD of GaAs wafer normally is <5000/cm2 for LED or <500/cm2 for LD or microelectronics.
