Semiconductor cleanrooms ua lub luag haujlwm tseem ceeb hauv kev tsim cov chips. Ua raws li ISO cov qauv kev ua kom huv huv, lawv tsim cov kev txwv nruj rau kev cuam tshuam xws li micro- cov khoom, hluav taws xob zoo li qub, thaj chaw sib nqus, thiab qhov kub thiab txias hloov pauv. Cov lus qhia rail verticality thiab worktable txoj cai-angle reference ntawm wafer tshuaj xyuas cov cuab yeej, PCB drilling tshuab, hnyav-lub luag hauj lwm XY linear motor platforms, thiab optical test instruments ncaj qha txiav txim lub nti tawm los ntawm cov txheej txheem nrog rau photolithography, nyias - zaj duab xis deposition, thiab wafer probing.
Cov pa steel thiab cam khwb cia hlau sim squares nthuav qhia ntau yam kev lag luam mob thaum siv hauv chav huv. Cov khoom siv hlau yog magnetic conductive; Thaum muab tso rau ze rau optical sensors thiab precision probes, lawv tsim electromagnetic cuam tshuam uas distorts cov khoom ntsuas ntsuas. Steel nta ib coefficient siab ntawm thermal expansion. Txawm hais tias muaj qhov kub thiab txias me me hauv cov chav ua haujlwm thermostatically tswj, qhov siv lub kaum sab xis drifts tsis tu ncua dhau kev siv sijhawm ntev. Hlau nto yog oxidation thiab xeb. Kev ntxuav thiab ntxuav ua cov khib nyiab hlau uas ua rau cov chaw huv huv thiab ua rau muaj kev pheej hmoo ntawm cov khoom seem vim muaj cov khoom siv ntau dhau. Ordinary marble gauges muaj ntau sab hauv qhov pores uas nkag tau cov plua plav thiab muaj qhov tsis muaj zog. Nyob rau hauv kev ua haujlwm calibration nquag, cov npoo siv tau hnav sai heev, tshem tawm lawv cov nano- nplai calibration peev xwm. Leveraging tshwj xeeb rau lub cev thiab tshuaj pob zeb khoom, chav huv huv- cov txheej txheem ua tau zoo, thiab tag nrho - txheej txheem traceable metrology system, siab - ntom granite tri-squares tau dhau los ua qauv ntsuas ntsuas rau ntsuas cov khoom siv verticality hauv semiconductor cleanrooms.
1. High-Density Granite Substrates Fundamentally txaus siab rau Core Cleanroom Requirements: Anti-Static, Non-Magnetic & Tsawg Thermal Expansion
Granite tri-squares engineered rau semiconductor huv ib puag ncig yog fabricated los ntawm sib sib zog nqus- mined siab- ntom dub granite uas tau tso tawm kev ntxhov siab nyob rau hauv ntau pua lab xyoo ntawm natural aging. The material boasts far higher density than generic stone on the market, featuring a dense, pore-free internal structure. Qhov no tshem tawm cov plua plav adsorption thiab cov khib nyiab pov tseg ntawm cov khoom siv raw, ua tib zoo ua raws li cov qauv tswj kev huv huv.
Ua ntej, tag nrho tsis yog -magnetic thiab insulating zog tshem tawm electromagnetic cuam tshuam. Granite tsis muaj cov khoom siv hlau nplaum hlau nplaum, nrog rau kev sib nqus nqus ze rau xoom. Thaum muab tso rau ib sab ntawm cov cuab yeej tshuaj xyuas wafer, CD-SEM, thiab CMM sojntsuam, nws yuav tsis cuam tshuam qhov tseeb ntawm qhov ntsuas qhov taw qhia lossis nyiam cov hmoov av me me los ntawm kev cob qhia. Tsis tas yuav muaj kev kho demagnetization ntxiv, ua rau nws tsim nyog rau calibrating tag nrho cov hom semiconductor precision instruments rhiab heev rau magnetic teb.
Qhov thib ob, qhov ultra- qis coefficient ntawm thermal expansion tiv thaiv kev siv drift nyob rau hauv cov kev cob qhia uas tswj cov ntsuas kub. Txawm tias muaj me me ± 1℃qhov kub thiab txias hloov pauv los ntawm cov tshuab cua txias, qhov deformation ntawm siab - ntom granite tsuas yog ib qho - kaum ntawm cov hlau. 90℃txoj cai-lub kaum sab xis siv ntawm tri-square yuav tsis raug kev txom nyem angular offset los ntawm qhov kub thiab txias. Cov khoom siv cyclic calibration cov ntaub ntawv muab kev rov ua tau zoo dua qub, zam kev tsis ncaj ncees ntawm cov lus qhia rail verticality tshwm sim los ntawm thermal deformation ntawm gauges thiab txo cov kev pheej hmoo ntawm cov chips loj.
Thib peb, cov khoom siv tau zoo heev, corrosion-cov khoom siv tiv taus yog yooj yim los ntxuav, ua raws li kev ua haujlwm huv chav ua haujlwm niaj hnub. Lub pob zeb nta xoom capillary pores thoob plaws nws qhov loj. Cov ntaub so huv tshwj xeeb ua ke nrog cov neeg ua haujlwm tu nruab nrab tuaj yeem so sai sai so cov khoom seem uas tsis muaj cuab yeej av thiab plua plav. Cov khoom tiv thaiv acids, alkalis, thiab txiav cov kua dej corrosion. Thaum muab tso rau ib sab ntawm wafer tu thiab PCB cov kab ntau lawm, kev cuam tshuam ntev rau cov txheej txheem tshuaj yuav tsis ua rau muaj kev xeb los yog hmoov av, ua raws li cov qauv huv huv.
2. Cov Plua Plav Tshwj Xeeb-Dawb & Kev vibration-Ib qho khoom siv ua haujlwm cais tawm kom ntseeg tau qhov tseeb ntawm Tri-Square Precision rau Nano- Cov khoom siv ntsuas ntsuas ntsuas
Cov khoom siv semiconductor imposes stringent yooj yim precision yuav tsum rau calibration references. Txhua qhov kev ua haujlwm tsis xws luag hauv tri-square's flatness, verticality, lossis parallelism ncaj qha yuav ua rau muaj kev ua yuam kev hauv cov khoom siv qhia kev sib tw. Tag nrho cov siab- ntom ntom granite tri-squares tau ua tiav machining nyob rau hauv ib qho kev ywj pheej semiconductor-qib huv chav nrog qhov kub thiab txias, qhov av tsis tu ncua, thiab plua plav-dawb tej yam kev mob. Lub rhiav yog haum nrog cov tub rog tuab tuab- qib pob zeb hauv pem teb, ncig los tiv thaiv- kev vibration trenches, thiab ntsiag to overhead cranes. Cov yam ntxwv no cais tag nrho cuam tshuam rau kev sib tsoo cov txheej txheem los ntawm lwm lub tshuab cuab yeej kev co thiab huab cua turbulence, tiv thaiv cov machining kev nyuaj siab uas yuav degrade precision lub sij hawm.
Cov txheej txheem ntau lawm siv ntau- theem kev sib tsoo txheej txheem. Tom qab kev sib tsoo ntxhib tshem tawm cov pob zeb ntau dhau, cov khoom ua haujlwm so kom tso siab rau kev ua haujlwm ua ntej semi- tiav kev sib tsoo thiab nano- nplai phau ntawv polishing. Sib tsoo cov kws tshaj lij nrog ntau xyoo ntawm ob txhais tes- ntawm kev paub polish siv cov chaw ua haujlwm nyob rau ntawm cov mos mos micron- qib tactile rhiab heev. Cov khoom tiav tiav xa cov nano ruaj khov- nplai verticality thiab flatness, nrog rau txoj cai ntseeg tau tiag tiag -lub kaum sab xis xa khoom. Lawv txaus siab rau qhov nruj calibration kam rau ua ntawm siab -kawg semiconductor khoom nrog rau 300mm wafer tshuaj xyuas cov cuab yeej thiab siab -precision optical platforms.
Txhawm rau ua kom tau raws li kev xav tau ntawm chav huv huv rau kev tsim kho lub teeb thiab xoom cov khoom pov tseg, tri-square edges tau txais kev kho mob zoo heev uas tsis muaj qhov ntse, yooj yim chipped ridges. Thaum lub sij hawm kev thauj mus los thiab calibration los ntawm kev haum rau cov khoom siv qhia rails, kev sib tsoo yuav tsis tsim cov pob zeb tawg uas paug qhov chaw huv si. Cov chaw siv daim iav-qib polishing nrog qhov tshwj xeeb smoothness, inhibiting plua plav adhesion thiab txo qis rhiav tu workloads.
