Hauv kev sim semiconductor, kev xaiv cov khoom siv ntawm lub platform sim ua lub luag haujlwm tseem ceeb hauv kev sim qhov tseeb thiab kev ruaj khov ntawm cov khoom siv. Piv nrog cov ntaub ntawv hlau cam khwb cia ib txwm muaj, granite tau dhau los ua qhov kev xaiv zoo tshaj plaws rau cov platform sim semiconductor vim nws qhov kev ua tau zoo heev.
Kev tiv thaiv corrosion zoo heev ua kom ruaj khov ua haujlwm ntev
Thaum lub sijhawm kuaj semiconductor, ntau yam tshuaj reagents feem ntau koom nrog, xws li potassium hydroxide (KOH) kua siv rau kev tsim photoresist, thiab cov tshuaj corrosive heev xws li hydrofluoric acid (HF) thiab nitric acid (HNO₃) hauv cov txheej txheem etching. Cov hlau cam khwb cia feem ntau yog tsim los ntawm cov hlau. Hauv qhov chaw ib puag ncig tshuaj lom neeg zoo li no, cov tshuaj oxidation-reduction reactions yuav tshwm sim. Cov hlau atoms poob electrons thiab dhau los ua cov tshuaj hloov pauv nrog cov tshuaj acidic hauv cov tshuaj, ua rau muaj kev xeb sai ntawm qhov chaw, tsim cov xeb thiab kev nyuaj siab, thiab ua rau puas tsuaj rau qhov tiaj tus thiab qhov tseeb ntawm lub platform.
Nyob rau hauv kev sib piv, cov khoom siv hauv cov pob zeb granite muab nws nrog kev tiv thaiv corrosion zoo kawg nkaus. Nws cov khoom tseem ceeb, quartz (SiO₂), muaj cov khoom siv tshuaj lom neeg ruaj khov heev thiab tsis tshua muaj kev cuam tshuam nrog cov kua qaub thiab cov hauv paus. Cov zaub mov xws li feldspar kuj tsis muaj zog hauv cov chaw ib puag ncig tshuaj lom neeg. Ntau qhov kev sim tau qhia tias nyob rau hauv tib qho chaw simulated semiconductor nrhiav pom tshuaj lom neeg, kev tiv thaiv corrosion tshuaj ntawm granite yog ntau dua 15 npaug ntau dua li ntawm cov hlau cam khwb cia. Qhov no txhais tau tias kev siv granite platforms tuaj yeem txo qhov zaus thiab tus nqi ntawm kev saib xyuas cov khoom siv los ntawm kev xeb, ntev lub neej kev pabcuam ntawm cov khoom siv, thiab xyuas kom meej qhov ruaj khov ntev ntawm kev kuaj pom tseeb.
Kev ruaj khov siab heev, ua tau raws li qhov yuav tsum tau ua ntawm nanometer-level detection accuracy
Kev kuaj semiconductor muaj qhov yuav tsum tau ua siab heev rau kev ruaj khov ntawm lub platform thiab xav tau kev ntsuas qhov tseeb ntawm cov yam ntxwv ntawm lub nti ntawm nanoscale. Tus coefficient ntawm thermal expansion ntawm cov hlau cam khwb cia yog qhov siab, kwv yees li 10-12 × 10⁻⁶ / ℃. Cov cua sov tsim los ntawm kev ua haujlwm ntawm cov khoom siv kuaj pom lossis qhov hloov pauv ntawm qhov kub thiab txias yuav ua rau muaj kev nthuav dav thermal thiab kev cog lus ntawm lub platform hlau cam khwb cia, ua rau muaj kev sib txawv ntawm qhov chaw ntawm qhov kev soj ntsuam kuaj pom thiab lub nti thiab cuam tshuam rau qhov tseeb ntawm kev ntsuas.
Tus coefficient ntawm thermal expansion ntawm granite tsuas yog 0.6-5 × 10⁻⁶ / ℃, uas yog ib feem lossis qis dua ntawm cov hlau cam khwb cia. Nws cov qauv yog ntom. Qhov kev ntxhov siab sab hauv tau raug tshem tawm los ntawm kev laus ntuj ntev thiab tsawg kawg cuam tshuam los ntawm kev hloov pauv kub. Tsis tas li ntawd, granite muaj lub zog rigidity, nrog rau qhov nyuaj 2 txog 3 zaug siab dua li ntawm cov hlau cam khwb cia (sib npaug rau HRC > 51), uas tuaj yeem tiv taus kev cuam tshuam sab nraud thiab kev co thiab tswj qhov tiaj tus thiab ncaj ntawm lub platform. Piv txwv li, hauv kev kuaj pom qhov tseeb ntawm cov chip circuit, lub platform granite tuaj yeem tswj qhov yuam kev tiaj tus hauv ± 0.5μm / m, kom ntseeg tau tias cov khoom siv kuaj pom tseem tuaj yeem ua tiav qhov kev kuaj pom nanoscale precision hauv cov chaw nyuaj.
Cov cuab yeej tiv thaiv hlau nplaum zoo heev, tsim kom muaj ib puag ncig pom tseeb
Cov khoom siv hluav taws xob thiab cov sensors hauv cov khoom siv kuaj semiconductor muaj kev cuam tshuam zoo heev rau kev cuam tshuam electromagnetic. Cov hlau cam khwb cia muaj qee qib ntawm magnetism. Hauv qhov chaw electromagnetic, nws yuav tsim lub zog magnetic, uas yuav cuam tshuam rau cov teeb liab electromagnetic ntawm cov khoom siv kuaj, ua rau muaj kev cuam tshuam ntawm cov teeb liab thiab cov ntaub ntawv kuaj tsis zoo.
Ntawm qhov tod tes, Granite yog cov khoom siv antimagnetic thiab tsis tshua muaj polarized los ntawm cov teb magnetic sab nraud. Cov electrons sab hauv muaj nyob ua khub hauv cov tshuaj sib txuas, thiab cov qauv ruaj khov, tsis cuam tshuam los ntawm cov zog electromagnetic sab nraud. Hauv qhov chaw muaj zog magnetic ntawm 10mT, qhov muaj zog magnetic ntawm qhov chaw ntawm granite yog tsawg dua 0.001mT, thaum qhov ntawd ntawm qhov chaw ntawm cov hlau cam khwb cia yog siab txog ntau dua 8mT. Qhov no ua rau lub platform granite tsim ib puag ncig electromagnetic ntshiab rau cov khoom siv kuaj pom, tshwj xeeb tshaj yog haum rau cov xwm txheej nrog cov kev cai nruj rau suab nrov electromagnetic xws li quantum chip detection thiab high-precision analog circuit detection, ua kom zoo dua qhov kev ntseeg tau thiab kev sib xws ntawm cov txiaj ntsig kuaj pom.
Hauv kev tsim cov platform kuaj semiconductor, granite tau dhau los ntawm cov khoom siv hlau cam khwb cia vim nws cov txiaj ntsig zoo xws li kev tiv thaiv corrosion, kev ruaj khov thiab anti-magnetism. Raws li cov thev naus laus zis semiconductor nce qib mus rau qhov tseeb dua, granite yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau tias cov khoom siv kuaj thiab txhawb kev nce qib ntawm kev lag luam semiconductor.
