Babban hanyoyin haɓaka kristal da halayen su

(1) Hanyar Canja wurin Tururin Jiki (PTV)
Ƙa'ida: A yanayin zafi mai girma, albarkatun SiC suna haɓaka zuwa lokacin iskar gas, wanda daga baya aka sake yin recrystallized akan kristal iri.
Babban fasali:
Babban zafin jiki mai girma (2000-2500 ° C).
High quality, babban size 4H-SiC da 6H-SiC lu'ulu'u za a iya girma.
Girman girma yana jinkirin, amma ingancin crystal yana da girma.
Aikace-aikace: Ana amfani da shi a cikin wutar lantarki, na'urorin RF da sauran manyan filayen.

(2) Hanyar Lely
Ƙa'ida: Lu'ulu'u suna girma ta hanyar sublimation na lokaci-lokaci da recrystallization na SiC powders a yanayin zafi mai girma.
Babban fasali:
Tsarin girma ba ya buƙatar tsaba, kuma girman crystal yana da ƙananan.
The crystal quality ne high, amma girma yadda ya dace ne low.
Ya dace da binciken dakin gwaje-gwaje da kuma samar da ƙaramin tsari.
Aikace-aikacen: Ana amfani da shi sosai a cikin binciken kimiyya da shirye-shiryen ƙananan lu'ulu'u na SiC.

(3) Babban Hanyar Ci gaban Seed (TSSG)
Ƙa'ida: A cikin babban bayani mai zafi, SiC albarkatun ƙasa na narkewa da crystallizes akan kristal iri.
Babban fasali:
Yawan zafin jiki na girma yana da ƙasa (1500-1800 ° C).
Babban inganci, ƙananan lahani na SiC za a iya girma.
Girman girma yana jinkirin, amma daidaituwar crystal yana da kyau.
Aikace-aikacen: Ya dace da shirye-shiryen manyan lu'ulu'u na SiC, kamar na'urorin optoelectronic.

(4) Liquid Phase epitaxy (LPE)
Ƙa'ida: A cikin maganin ƙarfe na ruwa, SiC albarkatun ƙasa na haɓakar haɓakawa a kan ƙasa.
Babban fasali:
Yawan zafin jiki na girma yana da ƙasa (1000-1500 ° C).
Matsakaicin haɓaka mai sauri, dacewa da haɓakar fim.
Ingancin crystal yana da girma, amma kauri yana da iyaka.
Aikace-aikace: An fi amfani dashi don haɓakar epitaxial na fina-finai na SiC, kamar na'urori masu auna firikwensin da na'urorin optoelectronic.

Babban hanyoyin aikace-aikace na silicon carbide crystal makera

SiC crystal makera shine ainihin kayan aiki don shirya sic crystals, kuma manyan hanyoyin aikace-aikacen sa sun haɗa da:
Ƙirƙirar na'urar na'ura mai ƙarfi: Ana amfani da shi don haɓaka 4H-SiC masu inganci da lu'ulu'u na 6H-SiC azaman kayan daɗaɗa don na'urorin wuta (kamar MOSFETs, diodes).
Aikace-aikace: motocin lantarki, masu juyawa na hotovoltaic, samar da wutar lantarki na masana'antu, da dai sauransu.

Ƙirƙirar na'urar Rf: Ana amfani da shi don haɓaka ƙananan ƙarancin SiC lu'ulu'u azaman abubuwan da za a iya amfani da su don na'urorin RF don saduwa da manyan buƙatun sadarwar 5G, radar da sadarwar tauraron dan adam.

Ƙirƙirar na'urar Optoelectronic: Ana amfani da shi don haɓaka ingantattun lu'ulu'u na SiC azaman kayan maye don ledoji, masu gano ultraviolet da lasers.

Binciken kimiyya da ƙananan samar da tsari: don binciken dakin gwaje-gwaje da sabon haɓaka kayan aiki don tallafawa ƙididdigewa da haɓaka fasahar haɓakar SiC crystal.

Ƙirƙirar na'urar zafin jiki mai girma: Ana amfani da shi don haɓaka babban zafin jiki mai jure zafin SiC lu'ulu'u a matsayin kayan tushe don sararin samaniya da na'urori masu auna zafin jiki.

SiC tanderun kayan aiki da sabis da kamfanin ke bayarwa

XKH yana mai da hankali kan haɓakawa da kera kayan aikin murhun wuta na SIC, yana ba da sabis masu zuwa:

Kayan aiki na musamman: XKH yana ba da wutar lantarki na musamman tare da hanyoyin haɓaka daban-daban kamar PTV da TSSG bisa ga bukatun abokin ciniki.

Taimakon fasaha: XKH yana ba abokan ciniki goyon bayan fasaha don dukan tsari daga haɓaka tsarin haɓakar crystal zuwa kayan aiki.

Ayyukan horo: XKH yana ba da horo na aiki da jagoranci na fasaha ga abokan ciniki don tabbatar da ingantaccen aiki na kayan aiki.

Sabis na tallace-tallace: XKH yana ba da amsa da sauri bayan sabis na tallace-tallace da kayan haɓaka kayan aiki don tabbatar da ci gaba da samar da abokin ciniki.

Silicon carbide crystal girma fasahar (kamar PTV, Lely, TSSG, LPE) yana da muhimman aikace-aikace a fagen ikon lantarki, RF na'urorin da optoelectronics. XKH yana ba da kayan aikin wutar lantarki na SiC da cikakken sabis don tallafawa abokan ciniki a cikin babban sikelin samar da lu'ulu'u na SiC masu inganci da kuma taimakawa ci gaban masana'antar semiconductor.
