Chidule cha Molecular Beam Epitaxy (MBE)
Tekinoloje ya Molecular Beam Epitaxy (MBE) idapangidwa m'zaka za m'ma 1950s kukonza zida zamakanema zowonda za semiconductor pogwiritsa ntchito ukadaulo wa vacuum evaporation. Ndi chitukuko chaukadaulo wapamwamba kwambiri wa vacuum, kugwiritsa ntchito ukadaulo kwakulitsidwa mpaka gawo la sayansi ya semiconductor.
Chilimbikitso cha kafukufuku wa zida za semiconductor ndikufunika kwa zida zatsopano, zomwe zitha kupititsa patsogolo magwiridwe antchito adongosolo. Kenako, umisiri watsopano ukhoza kupanga zida zatsopano ndi umisiri watsopano. Molecular beam epitaxy (MBE) ndiukadaulo wapamwamba wa vacuum wa kukula kwa epitaxial (nthawi zambiri semiconductor). Amagwiritsa ntchito mtengo wotentha wa ma atomu kapena mamolekyu omwe amakhudza gawo limodzi la kristalo. Mawonekedwe apamwamba kwambiri a vacuum amalola kuti in-situ metallization ndi kukula kwa zida zotsekera pamalo omwe angokulira kumene a semiconductor, zomwe zimapangitsa kuti pakhale malo opanda kuipitsidwa.
MBE Technology
Epitaxy ya molekyulu ya molekyulu inkachitidwa mu vacuum yapamwamba kapena vacuum yokwera kwambiri (1 x 10).-8Pa) chilengedwe. Mbali yofunika kwambiri ya molecular mtengo epitaxy ndi mlingo wake otsika mafunsidwe, amene nthawi zambiri amalola filimu kuti epitaxial kukula pa mlingo zosakwana 3000 nm pa ola. Kutsika kotereku kumafuna vacuum yokwanira kuti ikwaniritse ukhondo wofanana ndi njira zina zoyikamo.
Kuti mukwaniritse vacuum yotalikirapo yomwe tafotokozazi, chipangizo cha MBE (selo la Knudsen) chili ndi malo ozizirirapo, ndipo malo otulutsiramo kwambiri a chipinda chokulirapo ayenera kusanjidwa pogwiritsa ntchito njira yamadzimadzi ya nayitrogeni. Nayitrojeni wamadzimadzi amaziziritsa kutentha kwa mkati mwa chipangizocho kufika pa 77 Kelvin (−196 °C). Kutentha kwapang'onopang'ono kungathe kuchepetsanso zonyansa mu vacuum ndikupereka mikhalidwe yabwino yoyika mafilimu opyapyala. Chifukwa chake, njira yoziziritsira yamadzimadzi ya nayitrogeni imafunikira kuti zida za MBE zizipereka mosalekeza komanso mosasunthika wa -196 °C wamadzi wa nayitrogeni.
Liquid Nayitrogeni Kuzirala Kuzungulira System
Vacuum liquid nitrogen kuzirala dongosolo limaphatikizapo,
● thanki ya cryogenic
● payipi chachikulu ndi nthambi vacuum jacketed chitoliro / vacuum jacketed payipi
● MBE wapadera gawo olekanitsa ndi vakuyumu jacketed utsi chitoliro
● mavavu osiyanasiyana okhala ndi vacuum
● chotchinga cha gasi-zamadzimadzi
● fyuluta yokhala ndi vacuum
● dynamic vacuum pump system
● Kuziziritsa ndi kuchotsa reheating system
HL Cryogenic Equipment Company waona kufunika kwa MBE madzi asafe nayitrogeni kuzirala dongosolo, bungwe luso msana kuti bwinobwino kupanga wapadera MBE madzi asafe nayitrogeni cooing dongosolo MBE luso ndi yathunthu vacuum insulat.edmapaipi, omwe amagwiritsidwa ntchito m'mabizinesi ambiri, mayunivesite ndi mabungwe ofufuza.
HL Cryogenic Equipment
HL Cryogenic Equipment yomwe idakhazikitsidwa mu 1992 ndi mtundu womwe umagwirizana ndi Chengdu Holy Cryogenic Equipment Company ku China. HL Cryogenic Equipment yadzipereka pakupanga ndi kupanga High Vacuum Insulated Cryogenic Piping System ndi Zida Zothandizira Zogwirizana nazo.
