ntub etching yog txheej txheem tshem tawm cov khoom siv kua chemicals lossis etchantstshem tawm cov ntaub ntawv los ntawm wafer. Cov patters tshwj xeeb yog txhais los ntawm photoresist lub ntsej muag ntawm lub wafer. Cov ntaub ntawv uas tsis muaj kev tiv thaiv los ntawm lub npog ntsej muag no raug tshem tawm los ntawm cov tshuaj ua kua.
Cov ntaub ntawv qhia twg raug tshem tawm?
Plag: Etching yog hais txog kev tshem tawm cov khoom ntawm qhov chaw wafer. Cov txheej txheem feem ntau yog ua ke nrog lithography txhawm rau xaiv thaj chaw tshwj xeeb ntawm wafer los ntawm cov khoom siv yuav raug tshem tawm.
Puas tshem tawm cov khoom?
Tshuaj etching yog ib txoj hauv kev engraving uas siv lub siab kub-kub tshuaj tsuag kom tshem tawm cov khoom los tsim ib daim duab mus tas li etched hauv hlau. Lub npog ntsej muag lossis tiv thaiv yog siv rau saum npoo ntawm cov khoom thiab yog xaiv tshem tawm, nthuav tawm cov hlau, los tsim cov duab uas xav tau.
Dab tsi yog cov kauj ruam ntawm kev ntub dej?
Ib txheej txheem ntub dej etching yuav raug muab faib ua peb (3) cov kauj ruam yooj yim: 1) diffusion ntawm etchant rau saum npoo kom tshem tawm; 2) cov tshuaj tiv thaiv ntawm etchant thiab cov khoom raug tshem tawm; thiab 3) diffusion ntawm cov tshuaj tiv thaiv byproducts los ntawm reacted nto.
Dab tsi yog siv los tshem tawm cov khoom hauv qhuav etching?
Dry etching yog hais txog kev tshem tawm cov khoom, feem ntau yog cov qauv npog ntawm cov khoom siv semiconductor, los ntawm kev nthuav tawm theCov khoom siv rau kev foob pob ntawm ions (feem ntau yog cov roj ntsha ntawm cov pa roj ntsha xws li fluorocarbons, oxygen, chlorine, boron trichloride; qee zaum nrog ntxiv ntawm nitrogen, argon, helium thiab lwm yam gases) uas …

Thaum lub sijhawm ua pa ntawm tes uas ntawm cov hauv qab no tso tawm los ntawm cov khoom lag luam?
Thaum lub sijhawm ua pa aerobic cellular, qabzib reacts nrog oxygen, tsim ATP uas tuaj yeem siv los ntawm tes. carbon dioxide thiab dej yog tsim los ntawm cov khoom lag luam. Hauv kev ua pa ntawm tes, qabzib thiab oxygen hnov qab tsim ATP.
Yuav ua li cas tshem tawm cov ntaub ntawv tshem tawm hauv kev pauv 2010?

Leej twg detering nyob rau hauv tag nrho cov nyob ntsiag to nyob rau sab hnub poob pem hauv ntej?
Detering yog tus neeg ua liaj ua teb los ntawm Txhua Tus Neeg Tsis Txaus Siabntawm Sab Hnub Poob los ntawm Erich Maria Remarque. Nws muaj siab mos siab muag, tshwj xeeb tshaj yog thaum nws los txog rau nees. Nws muaj kev kub ntxhov loj heev thaum nws hnov cov nees quaj thiab txawm sim tua lawv kom kawg lawv txoj kev txom nyem.
Dab tsi yog qhov ceev ntawm cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece?
1. Kev nrawm . Kev txiav ceev (v) ntawm ib lub cuab yeej yog qhov ceev uas cov hlau raug tshem tawm los ntawm lub cuab yeej ntawm lub workpiece. Nyob rau hauv ib lub tshuab dhos, nws yog lub peripheral ceev ntawm kev ua hauj lwm yav dhau los cov cuab yeej txiav qhia nyob rau hauv meters ib feeb.
