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

The silicon wafer manufacturing process is crystal pulling, silicon wafer dicing, silicon wafer grinding, chamfering, etching, polishing, cleaning and inspection, among which crystal pulling, silicon wafer polishing and inspection are the core links of silicon wafer manufacturing. As the basic semiconductor substrate, silicon wafers must have high standards of purity, surface flatness, cleanliness, and impurity contamination to maintain the original designed functions of the chip. The high-specification requirements of semiconductor silicon wafers make its manufacturing process complicated. The four core steps include polysilicon purification and polysilicon ingot casting, single crystal silicon wafer growth, and silicon wafer cutting and shaping. As a raw material for wafer fab, the quality of silicon wafers directly determines the stability of the silicon wafer application process. Large-size silicon wafers have become the future development trend of silicon wafers. In order to improve production efficiency and reduce costs, more and more large-size silicon wafers are used.

  • 12 "Prime Grade Silicon Wafer

    PAM-XIAMEN offer 300mm bare silicon wafers (12 inch) in prime grade, n type or p type, and the 300mm silicon wafer thickness is 775±15. Compared to other silicon wafer suppliers, Powerway Wafer’s silicon wafer price is more competitive with higher quality. 300mm silicon wafers have a higher yield per wafer than pervious large diameter silicon wafers.

  • 12 "Silicon Wafer 300mm TOX (Si Thermische Oxidation Wafer)

    PAM-XIAMEN offers 300mm silicon oxide wafer and dioxide wafer. Thermal oxide silicon wafer or silicon dioxide wafer is a bare silicon wafer with oxide layer grown by dry or wet oxidation process. The thermal oxide layer of the silicon wafer is usually grown in a horizontal tube furnace, and the silicon wafer oxide temperature range is generally 900 ℃ ~ 1200 ℃. Compared with CVD oxide layer, silicon wafer oxide layer has higher uniformity, better compactness, higher dielectric strength and better quality.

  • 12 "Test Grade Silicon Wafer

    PAM-XIAMEN offers 300mm bare silicon wafers (12 inch) dummy, test grade, n type or p type. Compared to other silicon wafer suppliers, Powerway Wafer offers professional service with competitive prices.

  • Epi-Wafer für Laserdiode

    GaAs based LD epitaxy wafer, which can generate stimulate emission, is widely used for fabricating laser diode since the superior GaAs epitaxial wafer properties make the device a low energy consumption, high efficiency, long lifetime and etc. In addition to gallium arsenide LD epi wafer, commonly used semiconductor materials are cadmium sulfide (CdS), indium phosphide (InP), and zinc sulfide (ZnS).

  • Float-Zone monokristallinem Silizium

    PAM-XIAMEN kann Float-Zone-Siliziumwafer anbieten, die durch das Float-Zone-Verfahren gewonnen werden. Monokristalline Siliziumstäbe werden durch Float-Zone-Wachstum gewonnen und dann die monokristallinen Siliziumstäbe zu Siliziumwafern verarbeitet, die als Float-Zone-Siliziumwafer bezeichnet werden. Da der zonengeschmolzene Siliziumwafer den Quarztiegel während des Schwebezonen-Siliziumprozesses nicht berührt, befindet sich das Siliziummaterial in einem suspendierten Zustand. Dadurch wird es während des Schwebezonenschmelzens von Silizium weniger verschmutzt. Der Kohlenstoffgehalt und der Sauerstoffgehalt sind niedriger, die Verunreinigungen sind geringer und der spezifische Widerstand ist höher. Es eignet sich für die Herstellung von Leistungsgeräten und bestimmten elektronischen Hochspannungsgeräten.

  • Wafer Foundry Services

Da für Experimente und Tests häufig Dummy-Siliziumwafer verwendet werden, sind deren Größe und Dicke in den meisten Fällen wichtige Faktoren. 100-mm-, 150-mm-, 200-mm- oder 300-mm-Dummy-Wafer sind verfügbar.

  • Cz monokristallinem Silizium

    PAM-XIAMEN, a monocrystalline bulk silicon producer, can offer <100>, <110> and <111> monocrystalline silicon wafers with N&P dopant in 76.2~200 mm, which are grown by CZ method. The Czochralski method is a crystal growth method, referred to as the CZ method. It is integrated in a straight-tube heat system, heated by graphite resistance, melts the polysilicon contained in a high-purity quartz crucible, and then inserts the seed crystal into the surface of the melt for welding. After that, the rotating seed crystal is lowered and melted. The body is infiltrated and touched, gradually raised, and finished or pulled through the steps of necking, necking, shouldering, equal diameter control, and finishing.

  • Siliziumepitaxialwafers

    Silicon Epitaxial Wafer(Epi Wafer) is a layer of epitaxial silicon single crystal 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 silicon layer. It also can be used for thin film transistor.
