Dej: Cov Pob Txheem "tsis pom kev" ntawm Chip Raug
Los ntawm cov xov tooj ntawm lub xov tooj ntse peb siv txhua hnub rau cov tsheb uas tsav lub neej tom ntej, hluav taws xob sandiconductor chips yog ubiquitous; Lawv yog lub plawv ntawm cov thev naus laus zis tshiab. Tab sis ob peb tus neeg paub tias tom qab cov me me no tseem muaj tej yam me me, ib qho ntawm feem ntau cov tshuaj yeeb tshuaj uas muaj kev txhawb nqa ntsiag to- dej. Qhov no tsis yog dej dog dig, tab sis muaj cov dej ultrape uas tau txais kev kho nruj. Yog li ntawd, ib qho kev kawm siab heev thiab txhim khu kev qhasemiconductor rov qab osmosis systemyog qhov tsis tseem ceeb thiab tseem ceeb ntawm cov khoom siv hauv cov txheej txheem ntau lawm.
Vim li cas tsis muaj dej zoo li dej txaus?
Lub ntiaj teb no yog lub ntiaj teb xav tau rau huab ua siab ntxwv
Lub semiconductor tsim cov txheej txheem, tshwj xeeb tshaj yog nyob rau hauv cov theem ntau lawm, tuaj yeem piav qhia raws li precision engineering hauv lub ntiaj teb me me. It involves a series of complex physical and chemical steps, such as photolithography, etching, and thin-film deposition. Nyob rau hauv no nano - cov chaw ua haujlwm ua haujlwm, qhov yuav tsum tau ua rau ib qho kev coj tsis taus ib puag ncig mus txog ib puag ncig "qib. Impurities pom nyob rau hauv cov dej dog dig, xws li cov ions, microorgical hais, thiab cov kab mob zoo li cov kab mob, yog txhua tus neeg tuag taus "rau lub nti.
Txawm tias ib qho me me, ua kom pom tseeb kom pom lub qhov muag liab qab, ib qho tuaj yeem ua rau lub sijhawm luv lossis qhib Circuit Court ntawm lub nti; ions hauv dej tuaj yeem cuam tshuam cov hluav taws xob cov khoom ntawm lub semiconductor, ncaj qha rau kev poob hauv nti lossis txawm tias nws ua tiav tiav. Yog li ntawd, qhov tseem ceeb ntawm kev kho dej hauv semiconductor kev lag luam yog tus kheej- pom tseeb, raws li nws ntseeg tau thiab ntseeg tau ntawm cov khoom kawg.
Yuav ua li cas yog ultrapecture dej "forged"?
Txheej los ntawm txheej ua kom huv, poob los ntawm kev poob ntawm kev ua tiav
Txhawm rau kom muaj cov dej ultrapure uas tau ntsib cov qauv tsim khoom, cov txheej txheem dej ua haujlwm nyuaj rau cov txheej txheem dej. Qhov no feem ntau suav nrog cov theem ua ntej zoo li kev tshaj tawm thiab kev ua kom pom tseeb, cov tseem ceeb ua kom huv, kev kho mob tseem ceeb ntawm kev kho mob polishing. Los ntawm cov khaubncaws sab nraud povtseg ntawm kev tiv thaiv thiab cov kauj ruam ntawm kev ua kom huv, cov zis kawg yog ultrapure dej rau seviconductor manufacturing nrog kev tiv thaiv tsis tshua muaj siab.
Qhov kev ntsuam xyuas cov txheej txheem no tsis tsuas yog cov khoom siv nws tus kheej tab sis kuj nkag siab tob thiab kev sib xyaw ua ke ntawm cov txheej txheem kev kho dej. Peb lub tuam txhab, muaj kev dag ntxias nws cov tshuaj thev naus laus zis hauv cov kev txawj ntse hauv qib siab thiab muaj kev sib txuam ua ke, yog qhov ruaj khov rau kev lag luam microelectrity. Ib qho tshwj xeeb sandiconductor thim rov qab osmosis system, raws li cov tub ntxhais tseem ceeb ntawm cov impurities thiab ions ntawm cov dej, tso lub hauv paus rau cov theem txuas ntxiv.
Peb kev cog lus thiab lub zog
Hauv cov ntsiab lus, cov semiconductor kev lag luam txoj kev xav tau heev rau dej yog kom ntseeg tau tias txhua tus tib leeg tuaj yeem ua tiav nws cov kev ua tau tsim. Taihe ib puag ncig, nrog nws cov thawj coj hauv kev ua kom muaj zog thiab cov neeg siv hluav taws xob ruaj khov, pab kom cov neeg siv khoom ruaj khov thiab txhim kho cov txheej txheem lim dej hauv lawv qhov chaw ua kom haum. Peb nkag siab tob txog tias kev ua haujlwm nyuajsemiconductor rov qab osmosis systemyog txoj sia rau lav kev nti zoo. Yog li ntawd, ib qho zoo thiab txhim khu kev qha sandiconductor thim rov qab osmosis system yog qhov lav tau rau txhua qhov no.
