Ntu 1: Cov Kev Ua Haujlwm ntawm Lub Tshuab Nqus Tsev
Qhov thib ob: Kev tsim cov txheej txheem ntawm lub tshuab nqus tsev
Ntu 3: Kev sib tw ntawm cov khoom siv kev loj hlob
Ntu 1: Cov Kev Ua Haujlwm ntawm Lub Tshuab Nqus Tsev
Keeb kwm, kev yug me nyuam ntawm MBE cov cuab yeej tau dhau los ntawm cov txheej txheem ntev.Thaum ntxov photochemical evaporation thiab melting txoj kev tuaj yeem taug qab mus rau xyoo 1950, tab sis cov txheej txheem no muaj ntau yam kev txwv.Tom qab ntawd, molecular beam epitaxy tau los ua thiab tau dhau los ua txoj kev siv dav tshaj plaws, thiab nws kuj tau muab txoj hauv kev tshiab rau kev txhim kho thiab tsim khoom ntawm lub tshuab nqus tsev.
Lub tshuab nqus tsev vacuum hauv MBE cov cuab yeej yog ib qho tseem ceeb ntawm cov khoom siv uas tuaj yeem muab lub tshuab nqus tsev zoo tshaj plaws los xyuas kom zoo thiab ruaj khov ntawm cov khoom loj hlob.Lub tshuab nqus tsev vacuum no xav tau airtightness siab, siab kam rau siab thiab thermal stability, thiab yog tsim los ntawm cov ntaub ntawv tshwj xeeb thiab cov tswv yim.
Lwm qhov tseem ceeb yog lub tshuab nqus tsev vacuum, uas ua raws li lub foob thiab tswj lub tshuab nqus tsev hauv MBE cov cuab yeej.Txhawm rau kom ntseeg tau tias cov khoom siv tau zoo thiab kev ntseeg siab, lub tshuab nqus tsev yuav tsum muaj kev sib khi zoo heev thiab kev hloov pauv, thiab tsim los ntawm cov khoom siv zoo thiab cov txheej txheem tsim khoom.
Qhov thib ob: Kev tsim cov txheej txheem ntawm lub tshuab nqus tsev
Kev tsim lub tshuab nqus tsev chamber Cheebtsam yuav tsum muaj cov txheej txheem tsim khoom zoo heev.Cov kev xav tau rau kev xaiv cov khoom raug, kev siv tshuab, qhov tseeb qhov tseeb thiab qhov chaw tiav yog siab heev.Nyob rau tib lub sijhawm, cov cuab yeej siv qib siab thiab thev naus laus zis yuav tsum tau ua kom ntseeg tau qhov zoo thiab ruaj khov ntawm kev tsim khoom.Piv txwv li, kev xaiv ntawm cov ntaub ntawv yuav tsum tau xav txog ntau yam xws li kub, tsis tshua muaj kub thiab tshuaj corrosion, thiab cov txheej txheem txheej txheem yuav tsum tau xyuas kom meej qhov tseeb qhov ntev thiab nto tiav, uas yuav tsum tau advanced cov cuab yeej thiab technology kom ua tiav.Nyob rau tib lub sijhawm, muaj qee qhov kev ua haujlwm siab, xws li laser ua, electrochemical ua, thiab lwm yam, nrog rau kev tshawb fawb thiab thev naus laus zis, xws li tshuaj vapor deposition, lub cev vapor deposition, thiab lwm yam.
Nrog rau kev txhim kho txuas ntxiv ntawm MBE thev naus laus zis, qhov kev thov rau lub tshuab nqus tsev chamber tseem nce ntxiv.Tsis tsuas yog lawv tuaj yeem ua lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm cov khoom siv semiconductor, tab sis lawv kuj tuaj yeem siv rau hauv lwm yam kev siv, xws li kev tsim cov khoom siv kho qhov muag zoo, cov khoom siv semiconductor, thiab lwm yam. tuaj yeem siv los tsim cov ntaub so ntswg, kho cov ntaub so ntswg tsis xws luag, thiab lwm yam, thiab muaj kev thov dav dav.
Ntxiv nrog rau kev sib txawv ntawm daim ntawv thov teb, qhov zoo ntawm cov khoom siv technology loj hlob muaj xws li cov txheej txheem kev npaj yooj yim, muaj zog tswj, tsis muaj nqi, kev npaj ceev ceev thiab lwm yam.Cov txiaj ntsig zoo no ua rau cov khoom siv kev loj hlob ntawm cov cuab yeej siv tau dav thiab siv tau.
Ntu 3: Kev sib tw ntawm cov khoom siv kev loj hlob
Txawm li cas los xij, cov khoom siv technology loj hlob kuj ntsib qee qhov teeb meem hauv cov txheej txheem thov.Ua ntej tshaj plaws, cov txheej txheem kev loj hlob ntawm cov ntaub ntawv feem ntau cuam tshuam los ntawm ntau yam, xws li kub, siab, cua, reactant concentration, thiab lwm yam. .Qhov thib ob, cov teeb meem xws li kev loj hlob tsis sib xws thiab siv lead ua tsis xws luag tuaj yeem tshwm sim thaum cov txheej txheem kev loj hlob ntawm cov khoom.Cov teeb meem no yuav tsum tau txheeb xyuas thiab daws tau nyob rau lub sijhawm thaum lub sijhawm kev loj hlob, txwv tsis pub lawv yuav muaj kev cuam tshuam tsis zoo rau kev ua haujlwm ntawm cov khoom siv.
Ntxiv nrog rau kev sib txawv ntawm daim ntawv thov teb, qhov zoo ntawm cov khoom siv technology loj hlob muaj xws li cov txheej txheem kev npaj yooj yim, muaj zog tswj, tsis muaj nqi, kev npaj ceev ceev thiab lwm yam.Cov txiaj ntsig zoo no ua rau cov khoom siv kev loj hlob ntawm cov cuab yeej siv tau dav thiab siv tau.
GPM's Nqus Qhov Chaw Machining Peev Xwm:
GPM muaj kev paub dhau los hauv CNC machining ntawm lub tshuab nqus tsev.Peb tau ua haujlwm nrog cov neeg siv khoom hauv ntau qhov kev lag luam, suav nrog cov khoom siv hluav taws xob, khoom siv kho mob, thiab lwm yam, thiab tau cog lus los muab cov neeg siv khoom zoo, cov kev pabcuam machining zoo.Peb tau txais kev tswj hwm nruj nruj kom ntseeg tau tias txhua feem ua tau raws li cov neeg siv khoom xav tau thiab cov qauv.
