FZ Silicon Wafer

wehewehe

FZ Hoʻokahi Crystal Silicon Wafer,ʻO Float-zone (FZ) Silicon he silikoni maʻemaʻe loa me ka haʻahaʻa haʻahaʻa o ka oxygen a me nā haumia kalapona i huki ʻia e ka ʻenehana hoʻomaʻemaʻe ʻana i nā wahi lana.ʻO ka FZ Floating zone kahi ʻano ulu ulu ʻana o ka kristal i ʻokoʻa i ke ʻano CZ kahi i hoʻopili ʻia ai ke aniani hua ma lalo o ka polycrystalline silicon ingot, a hoʻoheheʻe ʻia ka palena ma waena o ka kristal hua a me ka silika kristal polycrystalline e ka RF coil induction heat no ka crystallization hoʻokahi.ʻO ka RF coil a me ka wahi hoʻoheheʻe e neʻe i luna, a paʻa kahi aniani hoʻokahi ma luna o ka kristal hua e like me ia.Hoʻopaʻa ʻia ka silikona Float-zone me ka hāʻawi ʻana i ka dopant like ʻole, ka hoʻololi resistivity haʻahaʻa, kaohi ʻana i ka nui o nā haumia, ke ola o ka mea lawe nui, ka pahuhopu resistivity kiʻekiʻe a me ke silika maʻemaʻe kiʻekiʻe.ʻO ka silikona Float-zone kahi ʻokoʻa maʻemaʻe kiʻekiʻe i nā kristal i ulu ʻia e ke kaʻina Czochralski CZ.Me nā hiʻohiʻona o kēia ʻano, ʻo FZ Single Crystal Silicon ka mea kūpono no ka hoʻohana ʻana i nā mea uila uila, e like me nā diodes, thyristors, IGBTs, MEMS, diode, mea RF a me nā mana MOSFETs, a i ʻole he substrate no ka mea hoʻonā kiʻekiʻe a i ʻole nā ​​​​mea ʻike maka. , nā mana mana a me nā mea naʻau, kiʻekiʻe ka pono solar cell etc.

Hāʻawi

Hiki ke hāʻawi ʻia ka FZ Single Crystal Silicon Wafer N-type a me P-type conductivity ma Western Minmetals (SC) Corporation i ka nui o 2, 3, 4, 6 a me 8 iniha (50mm, 75mm, 100mm, 125mm, 150mm a me 200mm) a hoʻonohonoho <100>, <110>, <111> me ka hoʻopau ʻana o ka ʻili o As-cut, Lapped, etched a poni ʻia i loko o ka pūʻolo pahu pahu a i ʻole cassette me ka pahu pahu ma waho.
