Menene Isostatic Graphite Crucible Mai Tsarkakakken Tsarkakakke?

Graphite Mai Tsabta Mai Tsabta (High-Tright Isostatic Graphite Crucible) akwati ne da aka ƙera da inganci wanda aka ƙera daga kayan graphite na isotropic waɗanda aka samar ta hanyar tsarin matsi na isostatic. Idan aka kwatanta da samfuran graphite na gargajiya, graphite na isostatic yana bayar da:

● Tsarin tsari iri ɗaya a kowane bangare

● Ƙarfin injina mai yawa da yawa

● Mafi kyawun ƙarfin lantarki na zafi

● Kyakkyawan juriya ga girgizar zafi

● Ƙananan ramuka

● Abubuwan da ke cikin ƙazanta marasa ƙanƙanta

Bayan tsarkakewa, yawanci ana iya sarrafa yawan tokar da ke cikinta a ƙasa da 5 ppm, tare da wasu kayan da aka yi amfani da su a matakin semiconductor waɗanda ke samun rashin tsarki a ƙasa da 3 ppm.

Waɗannan halaye sun sa High-Tsarkake Isostatic Graphite Crucibles ya dace da yanayin zafi mai yawa wanda ya wuce 2,000°C, inda ake buƙatar sarrafa gurɓatawa da daidaiton zafi.

Matsayin da ke cikin Masana'antar Semiconductor

A cikin haɓakar lu'ulu'u na Silicon Carbide (SiC) ta amfani da tsarin Fisik Vapor Transport (PVT), graphite crucibles suna aiki a matsayin jirgin ruwa na tattara kayan tushe da kuma wani muhimmin ɓangare na tsarin filin zafi. Suna aiki a yanayin zafi wanda yawanci ya wuce 2,200°C, crucible dole ne ya kiyaye daidaiton girma yayin da yake tallafawa daidaitattun yanayin zafin da ake buƙata don jigilar tururi da samuwar lu'ulu'u. Tsarkakakken tsari da isotropic na graphite kai tsaye yana shafar haɗakar ƙazanta, rarrabawar zafi, ƙimar girman lu'ulu'u, da samar da lahani.

Matsayin da Crucibles na Graphite Mai Tsabta Mai Tsabta ya wuce kera SiC zuwa fasahar ci gaban lu'ulu'u ta Gallium Nitride (GaN). Ko ana amfani da su a cikin HVPE, haɓakar flux, ko kuma hanyoyin samar da lu'ulu'u masu yawa, graphite crucibles suna samar da yanayi mai ɗorewa mai zafi wanda ke tallafawa jigilar kayayyaki da samuwar lu'ulu'u yayin da suke rage haɗarin gurɓatawa.

A cikin samar da kayan epitaxial na semiconductor, gami da SiC epitaxy, girma na lu'ulu'u na AlN, da kuma ci gaba da sarrafa semiconductor mai hade, graphite crucibles suna ba da gudummawa ga daidaiton zafi da kuma maimaita aiki. Kyakkyawan watsawar zafi da juriyarsu ga girgizar zafi suna ba da damar aiki mai dorewa a ƙarƙashin yanayin aiki mai tsauri, suna tallafawa daidaitaccen sarrafa ƙafewa, sublimation, da hanyoyin ajiya.

Gilashin Graphite Mai Tsabta Mai Inganci suma suna taka muhimmiyar rawa wajen kera kayan yumbu na zamani da foda na semiconductor na ƙarni na uku. A lokacin da ake yin sintering na silicon carbide, aluminum nitride, boron nitride, da sauran tukwane masu aiki sosai, gilashin yana samar da yanayi mai karko da daidaiton zafi wanda ke haɓaka yawan abu yayin da yake rage gurɓatawa. Ingantaccen aikin da aka samu a cikin tsarkin abu, ƙarfin wutar lantarki, da aikin injiniya suna da mahimmanci ga aikace-aikace tun daga kayan aikin semiconductor zuwa marufi na lantarki mai ƙarfi.

Yanayin Masana'antu da Ci gaban Nan Gaba

Yayin da na'urorin semiconductors masu faɗi-faɗi ke ci gaba da canza masana'antar lantarki ta wutar lantarki, buƙatar sabbin na'urorin graphite suna ƙaruwa cikin sauri.

Bukatun Tsarkakewa Mai Tsarkakakke

Aikace-aikacen semiconductor na gaba suna buƙatar matakan ƙazanta ƙasa da 5 ppm kuma, a wasu lokuta, kusan 1 ppm don tallafawa manyan girman lu'ulu'u da ƙarancin lahani.

Fasahohin Rufi

Ana ƙara amfani da ƙarin rufin saman a kan bututun graphite, gami da:

● Rufin Silicon Carbide (SiC)

● Rufin Tantalum Carbide (TaC)

● Rufin Pyrolytic Carbon (PyC)

Waɗannan fenti suna inganta:

● Juriyar tsatsa

● Daidaiton zafi

● Aikin rayuwa

● Tsaftace tsari

● Manyan Zane-zanen Crucible

Kasuwancin da aka yi:

● Wafers ɗin SiC mai inci 8

● Manyan abubuwan GaN

● Kayan aikin semiconductor na zamani

yana haifar da haɓaka manyan jiragen ruwa masu ƙarfi da ƙarfi waɗanda ke da ƙarfin sarrafa zafi a tsawon lokacin samarwa.
