Silicon & Compound Semiconductors
Western Minmetals (SC) Corporation WMC yog tus xa khoom loj ntawm 2-12 nti ib leeg siv lead ua los yog monocrystal silicon los ntawm kev siv tshuaj thiab rub cov thev naus laus zis.Czochralski UASthiabFloating Zone FZkom loj hlob siv lead ua los ntawm polycrystalline silicon, thiab ntau yam annealing, rounding, tu, slicing, etching thiab polishing txheej txheem thiab lwm yam tom qab ntawd.Ib leeg siv lead ua siliconFeem ntau yog rau kev tsim cov khoom sib xyaw ua ke, diodes, thyristors, transistors, cov khoom sib cais,khoom siv zog, zog MOSFET, IGBT thiab raws li lub substrate rau siab daws teeb meem particle lossis optical detectors thiab lwm yam.
Ua tsaug rau Magnetic-field-induced tsim rau tus qauv CZ ingot rub, MCZ ib leeg siv lead ua silicon yog qis dua cov pa oxygen, dislocation thiab uniform resistivity variation, thiab sib piv qis impurity concentration.FZ siliconqhia ntsug floating cheeb tsam refining tshuab los xyuas kom meej ib tug uniform dopant tis, qhov qis tshaj resistivity variation, txwv tus nqi ntawm impurities, lub neej muaj nuj nqis loj thiab ntxiv rau siab resistivity lub hom phiaj.Tsis tas li ntawd,FZ NTD (Neutron Transmutation Doping) silicon thiabEpitaxial Silicon WaferEPI tau txais CVD tau siv dav hauv kev tsim khoom siv hluav taws xob.
Muab lub ntiaj teb-chav kawm compound semiconductors, uas suav nrog tab sis tsis tsawgGallium Arsenide GaAs, Indium Arsenide InAs, Gallium Antimonide GaSb, Is Nrias teb Antimonide InSb,Indium Phosphide InP, Gallium Phosphide GAP, Silicon Carbide SiC, Gallium Nitride GaN thiab lwm yam rau LED, nano-integrated circuit, fais fab amplifier, optoelectronic sensors, infrared detectors, X-ray detectors, fais fab kis tau tus mob & tshiab zog.Tsis tas li ntawd, ib qho kev cog lus sib txuasSapphire Aluminium Oxide Al2O3Crystal yog yuav tsum yog cov ntaub ntawv tseem ceeb hauv optoelectronic, kev sib txuas lus siab, aeronautics thiab astronautics industries.
