Silicon Wafer

PAM-XIAMEN offers silicon wafer: FZ wafer, Test Wafer Monitor Wafer Dummy Wafer, Test Wafer,CZ wafer, epitaxial wafer, polished wafer, etching wafer.

  • Float-Zone Mono-Crystalline Silicon


    The mono-crystalline silicon with the characteristics of low foreign-material content, low defect density and perfect crystal structure is produced with the float-zone process; no foreign material is introduced during the crystal growth. The FZ-Silicon conductivity is usually above 1000 Ω-cm, and the FZ-Silicon is mainly used to produce the high inverse-voltage elements and photoelectronic devices.

  • Test Wafer Monitor Wafer Dummy Wafer

  • Cz Mono-Crystalline Silicon

    Cz Mono-Crystalline Silicon


    The heavily/lightly-doped CZ mono-crystalline silicon is suitable for producing various integrated circuits (IC), diodes, triodes, green-energy solar panel. The special elements (such as Ga, Ge) can be added to produce the high-efficiency, radiation-resistant and anti-degenerating solar cell materials for special components.

  • Epitaxial Silicon Wafer

    Epitaxial Silicon Wafer

    Silicon Epitaxial Wafer(Epi Wafer) is a layer of single crystal silicon deposited onto a single crystal silicon wafer(note: it is available to Grow a layer of poly crystalline Silicon layer on top of a highly doped Singly crystalline Silicon wafer,but it needs buffer layer (such as oxide or poly-Si) in between the bulk Si substrate and the top epitaxial layer)

  • Polished Wafer

    Polished Wafer

    FZ polished wafers, mainly for the production of silicon rectifier (SR), silicon controlled rectifier (SCR), Giant Transistor (GTR), thyristor (GRO)

  • Etching Wafer

    Etching Wafer

    The etching wafer has the characteristics of low roughness, good glossiness and relatively low cost, and directly substitutes the polished wafer or epitaxial wafer which has relatively high cost to produce the electronic elements in some fields, to reduce the costs. There are the low-roughness, low-reflectivity and high-reflectivity etching wafers.
