Kafushane kwe-Molecular Beam Epitaxy (MBE)
Ubuchwepheshe be-Molecular Beam Epitaxy (MBE) bathuthukiswa ngeminyaka yawo-1950 ukuze kulungiswe izinto zefilimu ezacile ze-semiconductor kusetshenziswa ubuchwepheshe be-vacuum evaporation. Ngokuthuthukiswa kobuchwepheshe be-vacuum obuphezulu kakhulu, ukusetshenziswa kobuchwepheshe kuye kwanwetshwa emkhakheni wesayensi ye-semiconductor.
Ukugqugquzelwa kocwaningo lwezinto ze-semiconductor yisidingo samadivayisi amasha, angathuthukisa ukusebenza kohlelo. Kanti, ubuchwepheshe obusha bezinto ezibonakalayo bungase bukhiqize imishini emisha nobuchwepheshe obusha. I-Molecular beam epitaxy (MBE) ubuchwepheshe obuphezulu be-vacuum bokukhula kwe-epitaxial layer (imvamisa ye-semiconductor). Isebenzisa ukushisa kwama-athomu omthombo noma ama-molecule athinta i-crystal substrate eyodwa. Izici ze-vacuum eziphezulu kakhulu zenqubo zivumela ukwenziwa kwe-metallization ye-in-situ kanye nokukhula kwezinto zokuvikela ezindaweni ezisanda kukhula ze-semiconductor, okuholela ekuxhumaneni okungenakho ukungcola.
I-MBE Technology
I-epitaxy ye-molecular beam yenziwa ku-vacuum ephezulu noma i-ultra-high vacuum (1 x 10).-8Pa) imvelo. Isici esibaluleke kakhulu se-epitaxy ye-molecular beam izinga layo eliphansi lokubeka, elivame ukuvumela ifilimu ukuthi i-epitaxial ikhule ngenani elingaphansi kuka-3000 nm ngehora. Izinga lokubeka eliphansi elinjalo lidinga isikhala esiphezulu esanele ukuze kufinyelelwe izinga lokuhlanzeka njengezinye izindlela zokubeka.
Ukuze kuhlangatshezwane ne-vacuum ephezulu kakhulu echazwe ngenhla, idivayisi ye-MBE (iseli ye-Knudsen) inesendlalelo sokupholisa, futhi indawo yokungena ephezulu kakhulu yegumbi lokukhula kufanele igcinwe kusetshenziswa isistimu yomjikelezo we-nitrogen ewuketshezi. I-nitrogen ewuketshezi ipholisa izinga lokushisa langaphakathi ledivayisi libe ngu-77 Kelvin (−196 °C). Indawo yokushisa ephansi ingaqhubeka nokunciphisa okuqukethwe kokungcola ku-vacuum futhi inikeze izimo ezingcono zokubekwa kwamafilimu amancane. Ngakho-ke, isistimu ezinikele yokupholisa i-nitrogen ewuketshezi iyadingeka ukuze okokusebenza kwe-MBE kuhlinzeke ngokuhlinzekwa okuqhubekayo nokuqhubekayo kwe- -196 °C ewuketshezi ye-nitrogen.
I-Liquid Nitrogen Cooling Circulation System
Isistimu yokupholisa ye-vacuum liquid nitrogen ikakhulukazi ihlanganisa,
● ithangi le-cryogenic
● Vacuum eyinhloko negatsha ipayipi elinejakhethi / vacuum jacketed ipayipi
● Isihlukanisi sesigaba esikhethekile se-MBE kanye nepayipi lokukhipha elifakwe i-vacuum jacket
● ama-vacuum jacketed ahlukahlukene
● umgoqo we-gas-liquid
● isihlungi esifakwe i-vacuum
● isistimu yephampu ye-vacuum enamandla
● Ukupholisa kuqala bese uhlanza isistimu yokushisisa kabusha
I-HL Cryogenic Equipment Company isibonile isidingo se-MBE liquid nitrogen cooling system, ihlele umgogodla wobuchwepheshe ukuthuthukisa ngempumelelo i-MBE liquid nitrogen cooing system yobuchwepheshe be-MBE kanye nesethi ephelele ye-vacuum insulat.eduhlelo lwamapayipi, olusetshenziswe emabhizinisini amaningi, amanyuvesi kanye nezikhungo zocwaningo.
I-HL Cryogenic Equipment
I-HL Cryogenic Equipment eyasungulwa ngo-1992 iwuphawu oluxhumene ne-Chengdu Holy Cryogenic Equipment Company eChina. I-HL Cryogenic Equipment izibophezele ekwakhiweni nasekukhiqizeni i-High Vacuum Insulated Cryogenic Piping System kanye Nezisetshenziswa Zokusekela ezihlobene.
