Luv luv ntawm Molecular Beam Epitaxy (MBE)
Lub tshuab ntawm Molecular Beam Epitaxy (MBE) tau tsim nyob rau xyoo 1950 los npaj cov khoom siv semiconductor nyias siv tshuab nqus tsev vacuum. Nrog rau txoj kev loj hlob ntawm lub tshuab nqus tsev ultra-siab, daim ntawv thov ntawm kev siv tshuab tau txuas ntxiv mus rau kev tshawb fawb semiconductor.
Kev txhawb siab ntawm kev tshawb fawb cov ntaub ntawv semiconductor yog qhov kev thov rau cov khoom siv tshiab, uas tuaj yeem txhim kho kev ua haujlwm ntawm lub cev. Nyob rau hauv lem, cov khoom siv technology tshiab yuav tsim cov cuab yeej tshiab thiab cov cuab yeej tshiab. Molecular beam epitaxy (MBE) yog lub tshuab nqus tsev siab rau cov txheej txheem epitaxial (feem ntau yog semiconductor) kev loj hlob. Nws siv lub teeb hluav taws xob ntawm qhov chaw atoms lossis cov molecules cuam tshuam rau ib qho siv lead ua substrate. Lub tshuab nqus tsev ultra-siab tus yam ntxwv ntawm tus txheej txheem tso cai rau hauv-situ metallization thiab kev loj hlob ntawm cov ntaub ntawv insulating ntawm cov tshiab zus semiconductor nto, uas ua rau muaj kuab paug-dawb interfaces.
MBE Technology
Lub molecular beam epitaxy tau nqa tawm hauv lub tshuab nqus tsev siab lossis ultra-high nqus (1 x 10-8Pa) Environment. Qhov tseem ceeb tshaj plaws ntawm molecular beam epitaxy yog nws qhov kev tso nyiaj tsawg, uas feem ntau tso cai rau cov yeeb yaj kiab rau epitaxial loj hlob ntawm tus nqi tsawg dua 3000 nm ib teev. Xws li tus nqi qis qis yuav tsum muaj lub tshuab nqus tsev txaus kom ua tiav tib theem ntawm kev huv raws li lwm txoj kev tso nyiaj.
Txhawm rau ua kom tau raws li lub tshuab nqus tsev siab tshaj plaws tau piav qhia saum toj no, MBE ntaus ntawv (Knudsen cell) muaj cov txheej txheem txias, thiab lub tshuab nqus tsev ultra-siab ntawm chav loj hlob yuav tsum tau khaws cia siv lub tshuab ua kua nitrogen. Cov kua nitrogen ua kom txias ntawm cov cuab yeej sab hauv rau 77 Kelvin (−196 ° C). Qhov kub thiab txias ib puag ncig tuaj yeem txo cov ntsiab lus ntawm impurities hauv lub tshuab nqus tsev thiab muab cov xwm txheej zoo dua rau kev tso tawm ntawm cov yeeb yaj kiab nyias. Yog li ntawd, ib qho kev mob siab rau cov kua nitrogen txias txias yuav tsum tau rau cov khoom siv MBE kom muab cov khoom siv tas mus li thiab khov kho ntawm -196 ° C kua nitrogen.
Kua Nitrogen Cooling Circulation System
Lub tshuab nqus tsev ua kua nitrogen txias ua haujlwm feem ntau suav nrog,
● cryogenic tank
● lub ntsiab thiab ceg lub tshuab nqus tsev jacketed yeeb nkab / lub tshuab nqus tsev vacuum jacketed hose
● MBE tshwj xeeb theem cais thiab lub tshuab nqus tsev vacuum tso pa tawm yeeb nkab
● ntau lub tshuab nqus tsev vacuum li qub
● gas-kua barrier
● lub tshuab nqus tsev lim
● dynamic lub tshuab nqus tsev twj tso kua mis
● Precooling thiab ntxuav reheating system
HL Cryogenic Equipment Lub Tuam Txhab tau pom qhov kev thov ntawm MBE kua nitrogen txias qhov system, txhim kho cov pob txha pob txha kom ua tiav qhov tshwj xeeb MBE kua nitrogen cooing system rau MBE thev naus laus zis thiab ua tiav txheej ntawm lub tshuab nqus tsev.edpiping system, uas tau siv nyob rau hauv ntau lub lag luam, cov tsev kawm qib siab thiab cov koom haum tshawb fawb.
HL Cryogenic khoom
HL Cryogenic Equipment tau tsim muaj nyob rau hauv 1992 yog ib hom lag luam koom nrog Chengdu Holy Cryogenic Equipment Company hauv Suav teb. HL Cryogenic Equipment tau cog lus rau kev tsim thiab tsim khoom ntawm High Vacuum Insulated Cryogenic Piping System thiab cov cuab yeej txhawb nqa.
