Yog tias koj xav qhwv koj lub taub hau ib ncig ntawm cov khoom tseem ceeb ntawm kev siv thev naus laus zis-los ntawm cov smartphones niaj hnub mus rau high-end desktop PCs-koj yuav tsum nkag siab txog FinFET thev naus laus zis.
FinFET yog dab tsi?
FinFET yog kev tsim kho thev naus laus zis uas tau tso cai cov tuam txhab nti xws li Samsung, TSMC, Intel, thiab GlobalFoundries los tsim cov khoom siv hluav taws xob me me thiab muaj zog dua.
Nws yog ib qho tseem ceeb ntawm kev tsim chip niaj hnub uas nws tau siv hauv kev lag luam ntawm cov txheej txheem nodes lawv tau ua raws. Ib qho piv txwv yog 7-nanometer (nm) FinFET txheej txheem thev naus laus zis ntawm lub hauv paus ntawm AMD tus thib peb tiam Ryzen CPUs. Nyob rau hauv xyoo tas los no, Nvidia tau siv TSMC's 16nm FinFET thev naus laus zis thiab Samsung's 14nm FinFET thev naus laus zis hauv nws 10 series graphics phaib tsim ntawm Pascal architecture.
Ib qho kev cuam tshuam ntawm FinFET Technology
Ntawm cov txheej txheem, FinFET, lossis cov fin field-effect transistor, yog ib hom hlau-oxide semiconductor transistor (MOSFET). Nws muaj ob lossis peb lub rooj vag qauv uas ua rau muaj kev ua haujlwm sai dua thiab muaj qhov ceev tam sim no ntau dua li cov qauv tsim. Qhov no ua rau cov kev xav tau qis dua, ib yam nkaus, ua rau FinFET tsim kom muaj zog ntau dua.
Txawm hais tias thawj FinFET transistor tsim tau tsim nyob rau hauv 1990s raws li lub npe ntawm Depleted Lean-channel Transistor, los yog DELTA transistor, nws tsis yog txog thaum ntxov-2000s uas lo lus FinFET tau coined. Nws yog cov lus luv luv, tab sis qhov "fin" ntawm lub npe tau pom zoo vim tias ob qho tib si lub hauv paus thiab cov cheeb tsam ntws ntawm MOSFET daim ntawv fins ntawm silicon nto nws tau tsim los ntawm.
FinFET Kev Siv Lag Luam
thawj kev lag luam siv FinFET thev naus laus zis yog nrog 25nm nanometer transistor tsim los ntawm TSMC hauv xyoo 2002. Nws tau lub npe hu ua "Omega FinFET" tsim, nrog rau kev rov ua dua ntawm lub tswv yim no los ntawm xyoo tom qab, suav nrog Intel's Tri-Gate variant, uas tau qhia hauv 2011 nrog nws 22nm Ivy Choj microarchitecture.
AMD kuj tau thov kom ua haujlwm ntawm cov thev naus laus zis zoo sib xws thaum ntxov 2000s, txawm tias tsis muaj dab tsi tiag tiag los ntawm nws. Thaum AMD rho tawm los ntawm nws cov tuav hauv GlobalFoundries hauv 2009, cov khoom lag luam thiab cov khoom siv tes ua lag luam tau raug txiav mus tas li.
Pib xyoo 2014, txhua lub tuam txhab loj nti-GlobalFoundries suav nrog-pib siv FiNFET thev naus laus zis raws li 16nm thiab 14nm thev naus laus zis, nws thiaj li txo qis ntawm qhov loj rau 7nm nrog qhov tseeb iterations.
Nyob rau xyoo 2019, kev txhim kho thev naus laus zis ntxiv tau tso cai rau kev txo qis dua qhov ntev ntawm FinFET rooj vag, ua rau 7nm. Hauv ob peb xyoos tom ntej no, peb yuav pom 5nm txheej txheem thev naus laus zis rau ntau lub zog thiab ua haujlwm zoo CPUs, daim npav duab, thiab System ntawm Chip (SoCs). Txawm li cas los xij, cov node qhov ntau thiab tsawg yog kwv yees nyob rau hauv feem ntau thiab tsis yog ib txwm ncaj qha piv nrog TSMC thiab Samsung qhov tseeb 7nm thev naus laus zis, uas tau hais tias kwv yees kwv yees li Intel's 10nm txheej txheem.
