Float-Zone Silicon Wafer With High-Resistivity And Good Lifetime.

Product Description

Float-Zone Silicon Wafer With High-Resistivity And Good Lifetime.

FZ-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.

NTDFZ-Silicon

The mono-crystalline silicon with high-resistivity and uniformity can be achieved by neutron irradiation of FZ-silicon, to ensure the yield and uniformity of produced elements, and is mainly used to produce the silicon rectifier (SR), silicon control (SCR), giant transistor (GTR), gate-turn-off thyristor (GTO), static induction thyristor (SITH), insulate-gate bipolar transistor (IGBT), extra HV diode (PIN), smart power and power IC, etc; it is the main functional material for various frequency converters, rectifiers, large-power control elements, new power electronic devices, detectors, sensors, photoelectronic devices and special power devices..

GDFZ-Silicon

Utilizing the foreign-material diffusion mechanism, add the gas-phase foreign-material during the float-zone process of monocrystalline silicon, to solve the doping problem of float-zone process from the root, and to get the GDFZ-silicon which is N-type or P-type, has the resistivity 0.001-300 Ω.cm, relative good resistivity uniformity and neutron irradiation. It is applicable for producing various semi-conductor power elements, insulate-gate bipolar transistor (IGBT) and high-efficiency solar cell, etc.

CFZ-Silicon

The monocrystalline-silicon is produced with the combination of Czochralski and float-zone processes, and has the quality between the CZ monocrystalline silicon and FZ monocrystalline silicon; the special elements can be doped, such as the Ga, Ge and others. The new-generation CFZ silicon solar wafers are better than various silicon wafers in global PV industry on each performance index; the conversion efficiency of solar panel is up to 24-26%. The products are mainly applied in the high-efficiency solar batteries with the special structure, back-contact, HIT and other special processes, and more widely used in the LED, power elements, automobile, satellite and other various products and fields.
