Hauv kev tsim khoom siv semiconductor, qhov tseeb yog txhua yam. Raws li kev tsim khoom siv chip txuas ntxiv mus rau qib nanometer thiab txawm tias qib nanometer, txhua qhov yuam kev me me yuav ua rau kev ua haujlwm ntawm chip poob qis lossis txawm tias ua tsis tiav. Hauv kev sib tw no rau qhov tseeb kawg, cov khoom siv granite precision, nrog lawv cov khoom siv lub cev thiab cov khoom siv kho tshuab tshwj xeeb, tau dhau los ua qhov tseem ceeb hauv kev ua kom muaj qhov tseeb ntawm nanoscale ntawm kev tsim khoom siv chip.
Kev ruaj khov zoo tshaj plaws tso lub hauv paus rau kev ua kom raug
Ib puag ncig hauv lub chaw ua haujlwm semiconductor muaj ntau yam nyuaj, thiab cov yam ntxwv sab nraud xws li kev co thiab kev hloov pauv kub tas li ua rau muaj kev phom sij rau qhov tseeb ntawm kev tsim khoom. Cov khoom siv granite precision muaj kev ruaj khov siab heev, muab lub hauv paus ruaj khov rau kev tsim cov chips. Nws cov qauv sab hauv yog ntom thiab sib xws, tsim los ntawm cov txheej txheem geological ntau pua lab xyoo, thiab nws muaj tus yam ntxwv ntuj tsim uas ua rau lub zog damping siab. Thaum cov kev co sab nraud raug xa mus rau cov khoom siv tsim khoom, cov khoom siv granite precision tuaj yeem nqus tau thiab txo qis ntau dua 80% ntawm lub zog co, txo qhov cuam tshuam ntawm kev co rau cov khoom siv precision.
Tus cwj pwm no tseem ceeb heev rau hauv cov txheej txheem photolithography. Photolithography yog ib kauj ruam tseem ceeb hauv kev hloov cov qauv tsim ntawm cov chips mus rau silicon wafers, uas xav tau lub rooj ua haujlwm ntawm lub tshuab photolithography kom muaj kev ruaj khov siab heev. Lub rooj ua haujlwm granite precision tuaj yeem cais cov kev cuam tshuam kev co los ntawm pem teb kev cob qhia thiab lwm yam khoom siv, kom ntseeg tau tias qhov yuam kev ntawm qhov chaw sib piv ntawm silicon wafer thiab lub ntsej muag photolithography raug tswj hwm ntawm qib nanometer thaum lub sijhawm raug ntawm lub tshuab photolithography, yog li lav qhov kev hloov pauv ntawm tus qauv.
Ntxiv mus, qhov coefficient ntawm thermal expansion ntawm granite yog qis heev, feem ntau yog li ntawm 5 txog 7 × 10⁻⁶ / ℃. Thaum lub sijhawm tsim khoom semiconductor, cua sov tsim los ntawm kev ua haujlwm ntawm cov khoom siv thiab qhov hloov pauv ntawm qhov kub thiab txias hauv chaw ua haujlwm tuaj yeem ua rau muaj kev hloov pauv thermal ntawm cov ntaub ntawv. Cov khoom siv granite precision yuav luag tsis cuam tshuam los ntawm kev hloov pauv kub thiab tuaj yeem tswj tau qhov ntev thiab cov duab ruaj khov. Piv txwv li, hauv cov txheej txheem etching chip, txawm tias qhov hloov pauv me ntsis ntawm qhov kub thiab txias tuaj yeem ua rau thermal nthuav dav ntawm cov khoom tseem ceeb ntawm cov khoom siv etching, ua rau muaj kev hloov pauv hauv qhov tob thiab qhov tseeb etching. Txawm li cas los xij, kev siv cov khoom siv granite precision ua kev txhawb nqa thiab cov khoom thauj khoom tuaj yeem tiv thaiv qhov xwm txheej no kom tsis txhob tshwm sim, ua kom ntseeg tau tias muaj qhov tseeb siab thiab sib xws ntawm cov txheej txheem etching.
Kev ua tiav siab thiab qhov zoo ntawm qhov chaw
Cov thev naus laus zis ua tiav siab ntawm cov khoom siv granite precision kuj yog ib qho tseem ceeb hauv kev ua kom muaj qhov tseeb ntawm cov chips. Los ntawm kev siv tshuab ua tiav siab heev, qhov tiaj tiaj ntawm qhov chaw, qhov ncaj thiab lwm yam ntsuas qhov tseeb ntawm cov khoom siv granite tuaj yeem ncav cuag qib siab heev. Piv txwv li, los ntawm kev siv CNC sib tsoo thiab polishing cov txheej txheem, qhov roughness ntawm qhov chaw ntawm granite tuaj yeem txo qis rau qib nanometer, ua rau qhov tiav ntawm qhov chaw zoo li daim iav.
Hauv cov khoom siv tsim cov chips, qhov zoo ntawm qhov chaw ntawm cov khoom xws li granite precision guide rails thiab sliders tuaj yeem txo qhov kev sib txhuam thiab kev hnav ntawm cov khoom txav mus los. Qhov no tsis yog tsuas yog ua kom muaj kev ruaj khov thiab qhov tseeb ntawm cov khoom siv txav mus los, tab sis kuj ua rau lub neej ua haujlwm ntawm cov khoom siv ntev dua. Piv txwv li, siv cov khoom siv ntim khoom chips. Cov granite guide rails uas raug tuaj yeem ua kom ntseeg tau tias qhov yuam kev ntawm txoj kev txav mus los ntawm lub taub hau ntim khoom thaum khaws thiab tso cov chips raug tswj ntawm micrometer lossis txawm tias nanometer theem, yog li ua tiav qhov sib phim meej thiab kev sib txuas txhim khu kev qha ntawm cov chips thiab cov khoom ntim khoom.
Tiv thaiv kev hnav thiab kev ruaj khov mus sij hawm ntev
Kev tsim khoom semiconductor yog ib qho txheej txheem tsim khoom tas mus li thiab ntev, thiab cov khoom siv yuav tsum ua haujlwm ruaj khov rau lub sijhawm ntev. Granite muaj kev tiv thaiv kev hnav zoo heev, nrog Mohs hardness ntawm 6 txog 7, muaj peev xwm tiv taus kev txav mus los ntev thiab kev thauj khoom. Hauv kev ua haujlwm txhua hnub ntawm cov khoom siv tsim khoom nti, cov khoom siv granite precision tsis yooj yim hnav thiab tsim kua muag thiab tuaj yeem tswj tau kev ua haujlwm ruaj khov thiab raug.
Piv nrog rau lwm cov ntaub ntawv, granite tsis muaj kev qaug zog deformation lossis kev ua haujlwm poob qis thaum siv ntev. Qhov no txhais tau tias cov khoom siv tsim cov chip siv cov khoom granite precision tseem tuaj yeem tswj tau qhov tseeb siab thiab ruaj khov tom qab kev ua haujlwm ntev, ua kom txo tau qhov tsis zoo ntawm cov khoom los ntawm kev poob qis ntawm cov khoom siv precision. Rau cov chaw tsim khoom semiconductor, qhov no tsis tsuas yog txhim kho kev ua haujlwm ntau lawm tab sis kuj txo cov nqi tsim khoom.
