Chidule cha ma molecular chowotcha chachikulu cha epitaxy (MBE)
Tekinoloje ya Blecular BEP ETITAXY (MBE) idapangidwa m'ma 1950s kuti akonzekere setimionduct zida zowonda pogwiritsa ntchito ukadaulo wambiri. Ndi kukula kwa ukadaulo wambiri wa ultraum, kugwiritsa ntchito ukadaulo kwapititsidwa ku gawo la semiconduct sayansi.
Zomwe zimapangitsa kuti semicockizacy ifotokozedwe kafukufuku ndiye kufunikira kwa zida zatsopano, zomwe zingakuyendere makonzedwe ake. Kutembenuka kumene, ukadaulo watsopano wazinthu zambiri ungatulutse zida zatsopano ndi ukadaulo watsopano. Molecular Brem Epitaxy (MBE) ndi ukadaulo wapamwamba wa vatucom yokwera ya epitaxial wosanjikiza (nthawi zambiri semiconducy) kukula. Imagwiritsa ntchito njira yoyatsira maatomu kapena mamolekyulu amasokoneza gawo limodzi. Makhalidwe a nthochi yayikulu ya njirayi amalola in-suti metalrization ndi kukula kwa zinthu zomwe zimayambitsa zigawo za semiconductor kumene, zomwe zimapangitsa kuwonongeka kwa mawonekedwe osasinthika.
MBC ukadaulo
Mtambo wa Molecular Heit adachitika mu vacuum wambiri wa vacuum kapena ultra-wamkulu (1 x 10-8Pa) malo. Mbali yofunika kwambiri yazomwe imakwera mtengo kwambiri wa epitaxy ndi kuchuluka kwake kochepa, komwe nthawi zambiri kumalola filimuyo ku epitaxial imakula pamlingo wochepera 3000 nm pa ola limodzi. Kuchuluka kotsika kumeneku kumafuna chibwibwi chokwanira chokwanira kuti mukwaniritse ukhondo monga njira zina zowonetsera.
Kukumana ndi vacuum ya Ultra-yayikulu yomwe yafotokozedwa pamwambapa, chipangizo cha KBADSE (cha Knudsen) chimakhala chilengedwe chozizira cha kukula chimayenera kusungidwa pogwiritsa ntchito njira yamadzi a nayitrogen. Madzi a nitrogen amazizira kutentha kwa chipangizocho mpaka 77 Kelvin (-196 ° C). Malo ofunda ozizira amatha kuchepetsa zomwe zili pabituzi ndikupereka malo abwino opangidwa ndi mafilimu oonda. Chifukwa chake, makina odzipereka a nayitrogeni ozizira amafunikira kuti apereke zida za MBE kuti apereke mayendedwe a -196 ° C yamadzi nayitrogeni.
Madzi a Nitrogen Ozizira
Vacuum yamadzi nitrogen ozizira kuzungulira makamaka,
● Cloragenic thank
● Nthambi zazikulu ndi nthambi zochulukitsa
● Mbedi yapadera ya MBE SANDES komanso chitoliro chopopera
● Ma Valum Ankakonda
● Cholepheretsa mpweya
● Fulu
● DZIKO LOPHUNZITSIRA
● Kukonzanso ndi kutsuka dongosolo
Kampani ya HOL Clogenic yawona kufunikira kwa mbewa ya mbewa ya mbewaedDongosolo la mafumu, lomwe lakhala likugwiritsidwa ntchito mu mabizinesi ambiri, mayunivesite ndi ofufuza.
Zida za HL Crogenic
Zida za HL Clokunic zomwe zidakhazikitsidwa mu 1992 ndizophatikizika ku kampani yopatulika zopatulika zokongola ku China. Zida za HL Crogenic zimapangidwa ndi kapangidwe ka vacuum yayitali yomwe idatulutsa masipoti a Crogenic omwe ali ndi zida zolumikizira.
