Lero Samsung Electronics za mapulani opangira njira zamakono zopangira ma semiconductors. Kampaniyo imawona kupanga ma projekiti a digito a tchipisi toyesa 3-nm kutengera ma transistors ovomerezeka a MBCFET kuti ndiye kupambana kwakukulu pakadali pano. Awa ndi ma transistors okhala ndi ma nanopage angapo opingasa m'zipata zoyimirira za FET (Multi-Bridge-Channel FET).
Monga gawo la mgwirizano ndi IBM, Samsung idapanga ukadaulo wosiyana pang'ono wopanga ma transistors okhala ndi mayendedwe ozunguliridwa ndi zipata (GAA kapena Gate-All-Around). Njirazo zinkayenera kupangidwa kukhala zoonda ngati nanowires. Pambuyo pake, Samsung idachoka pachiwembuchi ndikukhazikitsa ma transistor okhala ndi mayendedwe a nanopages. Kapangidwe kameneka kamakupatsani mwayi wowongolera mawonekedwe a transistors mwa kuwongolera masamba onse (njira) ndikusintha m'lifupi mwamasamba. Kwaukadaulo wakale wa FET, kuyendetsa koteroko sikutheka. Kuti muwonjezere mphamvu ya FinFET transistor, m'pofunika kuchulukitsa chiwerengero cha zipsepse za FET pa gawo lapansi, ndipo izi zimafuna dera. Makhalidwe a MBCFET transistor akhoza kusinthidwa mkati mwa chipata chimodzi chakuthupi, chomwe muyenera kuyika m'lifupi mwa njira ndi chiwerengero chawo.
Kupezeka kwa kapangidwe ka digito (kujambulidwa) kwa chipangizo chopangidwa pogwiritsa ntchito njira ya GAA kunalola Samsung kudziwa malire a kuthekera kwa ma transistors a MBCFET. Ziyenera kukumbukiridwa kuti iyi ikadali deta yachitsanzo cha makompyuta ndipo njira yatsopano yaukadaulo imatha kuweruzidwa pomaliza itatha kuyambika kupanga zambiri. Komabe, pali poyambira. Kampaniyo inanena kuti kusintha kuchokera ku ndondomeko ya 7nm (mwachiwonekere m'badwo woyamba) kupita ku ndondomeko ya GAA kudzapereka kuchepetsa 45% m'dera lakufa ndi kuchepetsa 50% pakugwiritsa ntchito. Ngati simusunga pazakudya, zokolola zitha kuwonjezeka ndi 35%. M'mbuyomu, Samsung idawona zosunga ndi zokolola posamukira ku njira ya 3nm olekanitsidwa ndi koma. Zinapezeka kuti zinali chimodzi kapena chimzake.
Kampaniyo imawona kukonzekera kwa nsanja yamtambo ya odziyimira pawokha tchipisi ndi makampani a fabless kukhala chinthu chofunikira pakulengeza ukadaulo wa 3nm. Samsung sinabise chilengedwe chachitukuko, kutsimikizira kwa projekiti ndi malaibulale pamaseva opanga. Pulatifomu ya SAFE (Samsung Advanced Foundry Ecosystem Cloud) ipezeka kwa opanga padziko lonse lapansi. Pulatifomu yamtambo ya SAFE idapangidwa ndikuchita nawo ntchito zazikulu zamtambo zapagulu monga Amazon Web Services (AWS) ndi Microsoft Azure. Opanga machitidwe opangira ma Cadence ndi Synopsys adapereka zida zawo zopangira mkati mwa SAFE. Izi zikulonjeza kuti zikhale zosavuta komanso zotsika mtengo kupanga mayankho atsopano a njira za Samsung.
Kubwerera kuukadaulo waukadaulo wa Samsung wa 3nm, tiyeni tiwonjeze kuti kampaniyo idapereka mtundu woyamba wa phukusi lake lachitukuko cha chip - 3nm GAE PDK Version 0.1. Ndi chithandizo chake, mutha kuyamba kupanga mayankho a 3nm lero, kapena kukonzekera kukumana ndi njira iyi ya Samsung ikafalikira.
Samsung yalengeza mapulani ake amtsogolo motere. Mu theka lachiwiri la chaka chino, kupanga kwakukulu kwa tchipisi pogwiritsa ntchito njira ya 6nm kudzayambitsidwa. Nthawi yomweyo, chitukuko chaukadaulo wa 4nm chidzamalizidwa. Kupanga zinthu zoyamba za Samsung pogwiritsa ntchito njira ya 5nm kumalizidwa kugwa uku, ndikuyambitsa kupanga mu theka loyamba la chaka chamawa. Komanso, pofika kumapeto kwa chaka chino, Samsung idzamaliza kupanga teknoloji ya 18FDS (18 nm pa FD-SOI wafers) ndi tchipisi ta 1-Gbit eMRAM. Matekinoloje oyambira pa 7 nm mpaka 3 nm adzagwiritsa ntchito makina ojambulira a EUV mwamphamvu, ndikupangitsa kuti nanometer iwerengedwe. Kupitilira panjira yotsika, sitepe iliyonse idzachitidwa ndi ndewu.
