Semixlab muab kev nkag mus rau lub ntiaj teb nthuav ntawm Semixlab rau cov tub ntxhais hluas nyeem ntawv txheej epitaxial thiab kev tsim cov semiconductors. Cov khaubncaws sab nraud povtseg Epitaxial yog qhov tseem ceeb rau kev tsim ntau yam khoom siv hluav taws xob ua haujlwm siab uas siv hauv lub neej txhua hnub ntawm tib neeg. Yog li ntawd, vim li cas cov khaubncaws sab nraud povtseg epitaxial thiaj li tseem ceeb? Cov khaubncaws sab nraud povtseg epitaxial yog dab tsi?
Cov txheej Epitaxial yog cov txheej nyias nyias uas loj hlob ntawm lub substrate hauv cov txheej txheem semiconductor. Cov txheej no raug ua kom zoo ib yam li lub hauv paus, yog li lwm cov ntaub ntawv semiconductor haum lawv zoo li dovetails. Thiab nws yog qhov tseem ceeb rau kev ua cov khoom siv hluav taws xob zoo heev, uas kev ua haujlwm ntawm cov ntaub ntawv yuav tsum tau ua tib zoo txwv.
Ib qho zoo ntawm cov txheej epitaxial yog los pab txhawb kev ua haujlwm zoo thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob. Cov tuam txhab muaj peev xwm txhim kho cov khoom siv hluav taws xob thiab lub teeb ci ntawm lub cuab yeej, rau kev ua haujlwm siab dua thiab kev siv hluav taws xob tsawg dua, los ntawm kev laminating ib txheej nyias ntawm cov khoom siv semiconductor rau saum lub hauv paus. Qhov ntawd ua rau nws tseem ceeb dua niaj hnub no, vim tias tib neeg xav tau cov khoom siv uas ceev dua, muaj zog dua thiab siv hluav taws xob tsawg dua.
Vim tias muaj ntau txoj hauv kev los cog ib txheej epitaxial hauv cov ntsiab lus ntawm kev ua cov semiconductor, txhua tus muaj nws qhov zoo. Ib txoj kev yog molecular beam epitaxy, qhov twg cov ntaub ntawv semiconductor raug txheej ib txheej atomic ib zaug. Raws li txoj kev no tso cai rau kev tswj hwm qhov tuab thiab cov khoom sib xyaw ntawm txheej epitaxial, nws yog qhov tsim nyog rau cov khoom siv ua haujlwm siab.
Muaj ib qho laj thawj zoo rau qhov kev xav ntawd: Cov khoom ntawm cov khaubncaws sab nraud povtseg epitaxial, thiab lawv tau tsim li cas, yog qhov tseem ceeb rau qhov ua haujlwm ntawm cov khoom siv hluav taws xob zoo li cas. Semixlab silicon epitaxial feem ntau cov khaubncaws sab nraud povtseg yog tsim los ntawm cov khoom siv semiconductor xws li silicon, gallium arsenide thiab indium phosphide uas muaj cov yam ntxwv hluav taws xob thiab lub teeb sib txawv.
Lwm yam tseem ceeb yog cov qauv siv lead ua ntawm cov txheej epitaxial thiab nws haum rau lub substrate. Kev sib phim zoo pab cov khoom siv semiconductor sib txawv, thiab qhov ntawd ua rau cov txiaj ntsig zoo dua. Lwm yam tseem ceeb yog qhov tuab ntawm cov txheej epitaxial uas tuaj yeem tswj tau raws li cov yam ntxwv tseem ceeb ntawm cov khoom siv.
Semixlab epitaxial susceptor Cov txheej txheej yog qhov tseem ceeb rau cov khoom siv semiconductor ua haujlwm siab uas txhawb nqa cov thev naus laus zis uas peb nyiam niaj hnub no. Qhov muaj cov txheej epitaxial tso cai rau cov chaw tsim khoom kom loj hlob cov khoom siv semiconducting sib xws nrog lub substrate kom tsim cov khoom siv hluav taws xob ua haujlwm siab thiab ua tau raws li qhov xav tau ntawm lub sijhawm tam sim no.
