Silicon & Compound Semiconductors
ʻO ka Western Minmetals (SC) Corporation WMC kahi mea hoʻolako nui o 2-12 iniha hoʻokahi aniani a i ʻole monocrystal silicon ma o ka doping pololei a me ka huki ʻana i nā ʻenehana.Czochralski CZaWahi Lana FZe ulu i ke aniani mai ka polycrystalline silicon, a me ka nui o ka annealing, ka poepoe, ka hoʻomaʻemaʻe, ka ʻoki ʻana, ka ʻili ʻana a me nā kaʻina hana polishing etc.Kilika kilika hoʻokahiʻO ka mea nui no ka hana ʻana i nā kaapuni i hoʻohui ʻia, nā diodes, thyristors, transistors, nā ʻāpana discrete,mea mana, mana MOSFET, IGBT a ma ke ʻano he substrate no ka ʻāpana hoʻonā kiʻekiʻe a i ʻole nā mea ʻike optical etc.
Mahalo i ka Magnetic-field-induced i hana ʻia i ka huki CZ ingot maʻamau, ʻo MCZ hoʻokahi kilikakika aniani o ka pae oxygen haʻahaʻa, dislocation a me ke ʻano like ʻole resistivity, a me ka hoʻohaʻahaʻa haʻahaʻa haʻahaʻa.FZ silikaka hoʻolauna ʻana i ka ʻenehana hoʻomaʻemaʻe ʻana i ka ʻenehana hoʻoheheʻe ʻia e hōʻoia i ka hāʻawi ʻana i ka dopant like ʻole, ka ʻokoʻa haʻahaʻa haʻahaʻa haʻahaʻa, kaohi i ka nui o nā haumia, ke ola o ka mea lawe nui a me ka pahuhopu resistivity kiʻekiʻe.Eia kekahi,FZ NTD (ʻO ka Doping Hoʻololi Neutron) silika aEpitaxial Silicon WaferHoʻohana nui ʻia ʻo EPI i ka CVD i nā mea uila uila.
Hāʻawi i ka honua-class compound semiconductors, e komo pū ana akā ʻaʻole liʻiliʻiGallium Arsenide GaAs, Indium Arsenide InAs, Gallium Antimonide GaSb, ʻO Indium Antimonide InSb,Indium Phosphide InP, Gallium Phosphide GaP, Silicon Carbide SiC, Gallium Nitride GaN etc no ka LED, nano-integrated circuit, power amplifier, optoelectronic sensors, infrared detection device, X-ray detectors, power transmission device & new energy source.Eia kekahi, he hui hoʻohikiSapphire Aluminum Oxide Al2O3ʻO ke aniani ke lilo i mau mea koʻikoʻi i ka optoelectronic, kamaʻilio alapine kiʻekiʻe, aeronautics a me nā ʻoihana astronautics.
