ʻO ka umu hoʻonui ʻo SiC crystal SiC Ingot e ulu ana i ka 4inch 6inch 8inch PTV Lely TSSG LPE ke ʻano ulu ulu.
ʻO nā ʻano hana ulu kristal nui a me kā lākou ʻano
(1) ʻO ke ʻano o ka hoʻololi ʻana i ka mahu kino (PTV)
Kumu: Ma nā wela kiʻekiʻe, hoʻohaʻahaʻa ʻia ka SiC maka i loko o kahi ʻāpana kinoea, a laila hoʻihoʻi hou ʻia ma ke aniani hua.
Nā hiʻohiʻona nui:
ʻO ka mahana ulu kiʻekiʻe (2000-2500 ° C).
Hiki ke hoʻoulu ʻia nā kristal kiʻekiʻe, nui nui 4H-SiC a me 6H-SiC.
He lohi ka ulu ʻana, akā ʻoi aku ka maikaʻi o ka kristal.
Noi: Hoʻohana nui ʻia i ka semiconductor mana, nā mea RF a me nā kahua kiʻekiʻe.
(2) Lely ala
Kumu: Hoʻoulu ʻia nā kristal e ka sublimation kuʻuna a me ka recrystallization o nā pauka SiC i nā wela kiʻekiʻe.
Nā hiʻohiʻona nui:
ʻAʻole pono ka ulu ʻana i nā hua, a he liʻiliʻi ka nui o ke aniani.
He kiʻekiʻe ka maikaʻi o ka kristal, akā he haʻahaʻa ka pono o ka ulu.
He kūpono no ka noiʻi keʻena hana a me ka hana liʻiliʻi.
Noi: Hoʻohana nui ʻia i ka noiʻi ʻepekema a me ka hoʻomākaukau ʻana i nā kristal SiC liʻiliʻi.
(3) ʻO ke ʻano o ka ulu ʻana o ka hoʻonā hua nui (TSSG)
Kumu: I loko o kahi hoʻonā wela kiʻekiʻe, hoʻoheheʻe ʻia ka mea maka SiC a hoʻoheheʻe ʻia ma ke aniani hua.
Nā hiʻohiʻona nui:
He haʻahaʻa ka mahana ulu (1500-1800 ° C).
Hiki ke hoʻoulu ʻia nā kristal SiC kiʻekiʻe.
He lohi ka ulu ʻana, akā maikaʻi ka like ʻana o ke aniani.
Noi: He kūpono no ka hoʻomākaukau ʻana i nā kristal SiC kiʻekiʻe, e like me nā mea optoelectronic.
(4) Liquid Phase epitaxy (LPE)
Kumu: I loko o ka wai hoʻonā metala, SiC raw mea ulu epitaxial ma luna o ka substrate.
Nā hiʻohiʻona nui:
He haʻahaʻa ka mahana ulu (1000-1500 ° C).
Ka ulu wikiwiki, kūpono no ka ulu kiʻiʻoniʻoni.
He kiʻekiʻe ka maikaʻi kristal, akā ua kaupalena ʻia ka mānoanoa.
Noi: Hoʻohana nui ʻia no ka ulu epitaxial o nā kiʻiʻoniʻoni SiC, e like me nā mea ʻike a me nā mea optoelectronic.
ʻO nā ala noi nui o ke kapuahi aniani carbide silicon
ʻO SiC crystal furnace ka mea nui no ka hoʻomākaukau ʻana i nā kristal sic, a ʻo kāna mau ala noi nui e komo pū ana:
Hana ʻia nā mea hana semiconductor mana: Hoʻohana ʻia e ulu i nā kristal 4H-SiC a me 6H-SiC kiʻekiʻe ma ke ʻano he mea substrate no nā mea mana (e like me MOSFET, diodes).
Nā noi: nā kaʻa uila, nā mea hoʻohuli kiʻi photovoltaic, nā lako mana ʻenehana, etc.
Hana ʻia nā mea hana Rf: Hoʻohana ʻia e ulu i nā kristal SiC haʻahaʻa haʻahaʻa ma ke ʻano he substrate no nā polokalamu RF e hoʻokō i nā pono kiʻekiʻe o nā kamaʻilio 5G, radar a me nā kamaʻilio satellite.
ʻO ka hana ʻana i nā mea hana optoelectronic: Hoʻohana ʻia e ulu i nā kristal SiC kiʻekiʻe e like me nā mea substrate no nā led, nā mea ʻike ultraviolet a me nā lasers.
Ka noiʻi ʻepekema a me ka hana liʻiliʻi liʻiliʻi: no ka noiʻi hoʻokolohua a me ka hoʻomohala ʻana i nā mea hou e kākoʻo i ka hana hou a me ka hoʻonui ʻana i ka ʻenehana ulu kristal SiC.
ʻO ka hana ʻana i nā hāmeʻa wela kiʻekiʻe: Hoʻohana ʻia e ulu i nā kristal SiC kūpaʻa kiʻekiʻe ma ke ʻano he kumu kumu no ka aerospace a me nā ʻike wela kiʻekiʻe.
ʻO nā lako kapuahi SiC a me nā lawelawe i hāʻawi ʻia e ka hui
Hoʻokumu ʻo XKH i ka hoʻomohala ʻana a me ka hana ʻana i nā lako kīʻaha SIC crystal furnace, e hāʻawi ana i nā lawelawe penei:
Nā lako hana maʻamau: Hāʻawi ʻo XKH i nā umu ulu maʻamau me nā ʻano ulu like ʻole e like me PTV a me TSSG e like me nā koi o ka mea kūʻai aku.
Kākoʻo ʻenehana: Hāʻawi ʻo XKH i nā mea kūʻai aku me ke kākoʻo ʻenehana no ke kaʻina holoʻokoʻa mai ka hoʻonui ʻana i ke kaʻina hana kristal a hiki i ka mālama ʻana i nā lako.
Nā lawelawe hoʻomaʻamaʻa: Hāʻawi ʻo XKH i ka hoʻomaʻamaʻa hana a me ke alakaʻi ʻenehana i nā mea kūʻai aku e hōʻoia i ka hana pono o nā mea hana.
ʻO ka lawelawe ma hope o ke kūʻai aku: Hāʻawi ʻo XKH i ka lawelawe wikiwiki ma hope o ke kūʻai aku a me ka hoʻomaikaʻi ʻana i nā mea hana e hōʻoia i ka hoʻomau ʻana o ka hana o ka mea kūʻai aku.
ʻO ka ʻenehana ulu ʻana o ka ʻenehana Silicon carbide crystal (e like me PTV, Lely, TSSG, LPE) he mau noi koʻikoʻi ma ke kahua o ka uila uila, nā mea RF a me nā optoelectronics. Hoʻolakoʻo XKH i nā lako kapuahi SiC kiʻekiʻe a me ka piha o nā lawelawe e kākoʻo i nā mea kūʻai i ka hana nui o nā kristal SiC kiʻekiʻe a kōkua i ka hoʻomohalaʻana i kaʻoihana semiconductor.
