Silicon txoj kev mus rau saum
Kev ua lag luam ua tsis tiav: Nws tau hais tias Shockley pom lub sijhawm ua lag luam loj heev ntawm lub sijhawm uas tsis muaj leej twg tseem ua tiav hauv kev ua silicon transistor;yog li ntawd nws thiaj tawm Bell Labs xyoo 1956 los pib nws lub tuam txhab hauv California.Hmoov tsis zoo, Shockley tsis yog ib tus neeg ua lag luam zoo thiab nws txoj kev tswj hwm kev lag luam yog ib tus neeg ruam ua haujlwm piv rau nws txoj kev kawm.Yog li ntawd Shockley nws tus kheej tsis ua tiav lub hom phiaj ntawm kev hloov germanium nrog silicon, thiab theem rau tag nrho nws lub neej yog lub podium ntawm Stanford University.Ib xyoos tom qab nws nrhiav tau, yim tus tub hluas txawj ntse uas nws tau xaiv los ntawm nws cov neeg coob coob, thiab nws yog "yim tus neeg ntxeev siab" uas yuav tsum ua kom tiav lub hom phiaj ntawm kev hloov germanium nrog silicon.
Qhov nce ntawm silicon transistor
Ua ntej Yim Renegades nrhiav tau Fairchild Semiconductor, germanium transistors yog lub lag luam tseem ceeb rau transistors, nrog ze li ntawm 30 lab transistors tsim nyob rau hauv Tebchaws Meskas xyoo 1957, tsuas yog ib lab silicon transistors thiab ze li ntawm 29 lab germanium transistors.Nrog 20% kev lag luam sib koom, Texas Instruments tau dhau los ua ib qho loj hauv kev lag luam transistor.
Cov neeg siv khoom loj tshaj plaws hauv kev ua lag luam, tsoomfwv Meskas thiab tub rog, xav siv cov chips loj hauv cov foob pob hluav taws thiab cov foob pob hluav taws, ua kom cov khoom muaj nqis tshaj tawm thiab txhim kho kev ntseeg siab ntawm cov chaw tswj xyuas.Tab sis cov transistors tseem yuav raug cuam tshuam rau kev ua haujlwm hnyav tshwm sim los ntawm qhov kub thiab txias thiab kev vibrations hnyav.
Germanium yog thawj zaug poob tawm thaum nws los txog rau qhov kub thiab txias: germanium transistors tuaj yeem tiv taus qhov kub ntawm tsuas yog 80 ° C, thaum cov tub rog yuav tsum tau ua haujlwm ruaj khov txawm tias nyob ntawm 200 ° C.Qhov tsuas yog ib qho uas tuaj yeem tiv taus qhov kub no yog silicon transistor.
Sendong tau tsim cov txheej txheem ntawm kev ua silicon transistors, ua rau lawv yooj yim thiab muaj txiaj ntsig zoo li cov ntawv luam tawm, thiab pheej yig dua li germanium transistors ntawm tus nqi.Fairchild txoj kev ua silicon transistors yog ntxhib raws li hauv qab no.
Firstly, ib tug layout yog kos los ntawm txhais tes, tej zaum kuj loj heev uas nws yuav siv sij hawm ib tug phab ntsa, thiab ces daim duab yog yees duab thiab txo mus rau ib tug me me translucent daim ntawv, feem ntau muaj ob txoj kab ntawm peb nplooj ntawv, txhua tus sawv cev ib txheej ntawm circuitry.
Qhov thib ob, ib txheej ntawm cov khoom siv lub teeb-rhiab yog siv rau cov hlais thiab polished du silicon wafer, thiab UV / laser yog siv los tiv thaiv cov qauv Circuit Court los ntawm daim ntawv transillumination mus rau silicon wafer.
Thib peb, cov cheeb tsam thiab kab hauv qhov tsaus ntuj ntawm daim ntawv transillumination tawm cov qauv tsis pom ntawm cov silicon wafer;Cov qauv uas tsis pom zoo no raug ntxuav nrog cov kua qaub, thiab ob qho tib si semiconductor impurities ntxiv (cov txheej txheem diffusion) los yog hlau conductors yog plated.
Thib plaub, rov ua dua peb cov kauj ruam saum toj no rau txhua qhov translucent wafer, ntau cov transistors tuaj yeem tau ntawm silicon wafers, uas yog txiav los ntawm cov poj niam cov neeg ua haujlwm hauv lub tshuab tsom iav thiab tom qab ntawd txuas nrog cov xov hlau, tom qab ntawd ntim, kuaj, thiab muag.
Nrog ib tug loj tus naj npawb ntawm silicon transistors nyob rau hauv kev ua lag luam, Fairchild, nrhiav tau los ntawm yim Traitors, yog ib tug ntawm cov tuam txhab uas muag uas muaj peev xwm sawv nrog xws li giants xws li Texas Instruments.
Tus tsav tsheb tseem ceeb - Intel
Nws yog qhov kev tsim kho tom ntej ntawm kev sib xyaw ua ke uas suav nrog kev tswj hwm ntawm germanium.Nyob rau lub sijhawm ntawd muaj ob txoj kab thev naus laus zis, ib qho rau kev sib koom ua ke ntawm germanium chips los ntawm Texas Instruments thiab ib qho rau kev sib xyaw ua ke ntawm silicon chips los ntawm Fairchild.Thaum xub thawj, ob lub tuam txhab muaj kev tsis sib haum xeeb txog kev ua tswv cuab ntawm patents ntawm kev sib koom ua ke, tab sis tom qab ntawd Patent Office tau lees paub cov tswv cuab ntawm patents ntawm kev sib koom ua ke los ntawm ob lub tuam txhab.
Txawm li cas los xij, raws li Fairchild cov txheej txheem tau nce siab dua, nws tau dhau los ua tus qauv rau kev sib xyaw ua ke thiab txuas ntxiv siv niaj hnub no.Tom qab ntawd, Noyce, tus neeg tsim khoom ntawm kev sib koom ua ke, thiab Moore, tus tsim ntawm Moore Txoj Cai, tawm ntawm Centron Semiconductor, uas, qhov xwm txheej, yog ob tus tswv cuab ntawm "Eight Traitors".Ua ke nrog Grove, lawv nrhiav tau dab tsi tam sim no lub ntiaj teb loj tshaj plaws semiconductor nti tuam txhab - Intel.
Hauv kev txhim kho tom ntej, Intel thawb silicon chips.Nws tuav Texas Instruments, Motorola, thiab IBM los ua tus huab tais ntawm semiconductor cia thiab CPU sector.
Raws li Intel tau los ua tus neeg tseem ceeb hauv kev lag luam, silicon kuj xaus germanium, thiab dab tsi yog thaum Santa Clara Valley tau hloov npe hu ua "Silicon Valley".Txij thaum ntawd los, silicon chips tau dhau los ua tib yam li semiconductor chips hauv pej xeem kev xav.
