Nhasi Samsung Electronics nezve zvirongwa zvekuvandudzwa kwehunyanzvi maitiro ekugadzirwa kwesemiconductors. Iyo kambani inoona kusikwa kwemapurojekiti edhijitari ekuyedza 3-nm machipisi akavakirwa patented MBCFET transistors kuve iyo huru budiriro iripo. Aya ndiwo ma transistors ane akawanda akachinjika nanopage chiteshi mumagedhi akatwasuka eFET (Multi-Bridge-Channel FET).
Sechikamu chemubatanidzwa neIBM, Samsung yakagadzira tekinoroji yakati siyanei yekugadzira ma transistors ane chiteshi chakakomberedzwa zvachose nemasuwo (GAA kana Gate-All-Around). Nzira dzaifanirwa kuitwa dzakatetepa nenzira ye nanowires. Zvadaro, Samsung yakasimuka kubva pachirongwa ichi uye ikaita patent ye transistor chimiro nemachaneli muchimiro che nanopages. Ichi chimiro chinokubvumira kudzora maitiro e transistors nekugadzirisa ese mapeji nhamba (channel) uye nekugadzirisa upamhi hwemapeji. Kune tekinoroji yeFET tekinoroji, maneja akadaro haagoneke. Kuti uwedzere simba reFinFET transistor, zvinodikanwa kuwedzera huwandu hweFET fins pane substrate, uye izvi zvinoda nzvimbo. Hunhu hweMBCFET transistor hunogona kuchinjwa mukati megedhi rimwe chete remuviri, raunoda kuseta hupamhi hwematanho uye nhamba yavo.
Kuwanikwa kwedhizaini yedhijitari (yakatemerwa kunze) yeprototype chip yekugadzira uchishandisa iyo GAA maitiro akabvumira Samsung kuona miganhu yekugona kweMBCFET transistors. Izvo zvinofanirwa kutakurwa mupfungwa kuti iyi ichiri dhata yekuenzanisira komputa uye iyo nyowani tekinoroji maitiro anogona chete kutongwa pakupedzisira mushure mekunge yatangwa mukugadzirwa kwakawanda. Zvisinei, pane pokutangira. Iyo kambani yakataura kuti shanduko kubva ku7nm process (zviri pachena chizvarwa chekutanga) kuenda kuGAA maitiro ichapa kuderedzwa kwe45% munzvimbo yekufa uye kuderedzwa kwe50% mukushandisa. Kana iwe ukasachengetedza pakushandisa, kubereka kunogona kuwedzerwa ne35%. Pakutanga, Samsung yakaona kuchengetedza uye kubudirira kwekubudirira pakufamba kune iyo 3nm maitiro zvakapatsanurwa nemakoma. Zvakazoitika kuti yaive imwe kana imwe.
Iyo kambani inoona gadziriro yeruzhinji gore chikuva chevanozvimiririra chip vanogadzira uye makambani asina fable sechinhu chakakosha mukuzivikanwa kweiyo 3nm process tekinoroji. Samsung haina kuvanza nharaunda yekusimudzira, kusimbiswa kweprojekiti uye maraibhurari pamaseva ekugadzira. Iyo SAFE (Samsung Advanced Foundry Ecosystem Cloud) chikuva ichavepo kune vanogadzira pasi rese. Iyo SAFE gore chikuva chakagadzirwa nekutora chikamu kweakadai makuru eruzhinji makore masevhisi seAmazon Web Services (AWS) uye Microsoft Azure. Vagadziri vekugadzira masisitimu kubva kuCadence uye Synopsys vakapa maturusi avo ekugadzira mukati meSEFU. Izvi zvinovimbisa kuita kuti zvive nyore uye zvakachipa kugadzira mhinduro nyowani dzeSamsung maitiro.
Kudzokera kune Samsung's 3nm process tekinoroji, ngatiwedzerei kuti kambani yakaratidza yekutanga vhezheni yayo chip kuvandudza package - 3nm GAE PDK Version 0.1. Nerubatsiro rwayo, unogona kutanga kugadzira 3nm mhinduro nhasi, kana kuti gadzirira kusangana neiyo Samsung maitiro kana yapararira.
Samsung inozivisa zvirongwa zvayo zveramangwana sezvinotevera. Muhafu yechipiri yegore rino, kugadzirwa kwakawanda kwemachipisi uchishandisa iyo 6nm maitiro kuchatangwa. Panguva imwecheteyo, kuvandudzwa kwe4nm process tekinoroji ichapedzwa. Iko kuvandudza kwekutanga Samsung zvigadzirwa uchishandisa iyo 5nm maitiro kuchapedzwa mukudonha uku, nekutanga kugadzirwa muhafu yekutanga yegore rinouya. Zvakare, pakupera kwegore rino, Samsung ichapedza kuvandudzwa kweiyo 18FDS process tekinoroji (18 nm paFD-SOI wafers) uye 1-Gbit eMRAM chips. Maitiro matekinoroji kubva pa7 nm kusvika 3 nm achashandisa EUV scanner nekuwedzera kusimba, zvichiita kuti nanometer yese iverenge. Kupfuurirazve munzira yekudzika, nhanho imwe neimwe ichatorwa nekurwa.
