Ubuchwepheshe Bokwenza Ama-Chip e-3nm Kwama-Smartphones
Ukuthuthukiswa kwama-smartphone eminyakeni eyishumi edlule kuhlobene kakhulu nentuthuko kwezobuchwepheshe be-semiconductor. Enye yezinto ezinkulu ezibonakala kakhulu njengamanje ukwenziwa kwama-chip angu-3-nanometer (3nm). Igama elithi "3nm" livame ukuvela ekuqalisweni kwamafoni amakhulu, okuthembisa ukusebenza okuthuthukisiwe, ukusebenza kahle kwamandla, kanye namakhono aphezulu ekhompyutha. Kodwa-ke, ngemuva kwalelo nani elincane kunenqubo yokukhiqiza eyinkimbinkimbi kakhulu, ehilela izinto ezithuthukisiwe, i-lithography enembile kakhulu, kanye nezindleko eziyinselele kanye nesivuno (izinga lempumelelo yokukhiqiza).
Buyini ubuchwepheshe be-3nm?
Kalula nje, ubuchwepheshe bokukhiqiza be-3nm bubhekisela “ku-node” yenqubo yokukhiqiza ama-chip. Esikhathini esidlule, inombolo ye-nanometer yayichaza usayizi othize ongokoqobo we-transistor, njengobude besango. Enkathini yanamuhla, leli nani liyigama lokukhiqiza ubuchwepheshe: uma inombolo incane, ngokuvamile ama-transistor angafakwa endaweni eyodwa yama-chip. Ubuningi be-transistor obuphezulu buvumela ama-CPU cores amaningi, ama-GPU, nama-Neural Processing Units (ama-NPU), ama-cache amakhulu, kanye nezici ezengeziwe ngobukhulu be-die obufanayo—noma usayizi we-die omncane osebenza ngokulinganayo.
Kumongo we-smartphone, i-node ye-3nm ivame ukusetshenziselwa i-System-on-Chip (SoC), "ubuchopho" befoni obuhlanganisa i-CPU, i-GPU, i-modem, i-ISP (Iphrosesa Yesiginali Yesithombe), kanye ne-AI accelerator. Ama-SoC e-3nm ahloselwe ukuletha okuhlangenwe nakho okusheshayo, okusebenzisa ibhethri kahle, nokupholile lapho kusetshenziswa imithwalo esindayo njengokudlala imidlalo, ukuqoshwa kwevidiyo okunesinqumo esiphezulu, kanye nokucutshungulwa kwe-AI kudivayisi.
Kungani i-3nm ibalulekile kuma-Smartphones?
Ama-Smartphones anemikhawulo eqinile ekusetshenzisweni kwamandla kanye nokushabalalisa ukushisa. Ngokungafani nama-PC edeskithophu, angasebenzisa ama-cooler amakhulu, amafoni athembele endaweni elinganiselwe kanye nemiklamo emincane. Njengoba umthwalo womsebenzi wanda, i-SoC kumele ihlale isebenza kahle ukuvimbela ukushisa ngokweqile kanye nokuphelelwa yibhethri.
Ubuchwepheshe be-3nm, ngokuvamile, bunikeza izinzuzo ezimbili eziyinhloko:
1. Ukusebenza kahle kwamandla okungcono: Ama-transistors amancane angasebenza ngama-voltage aphansi kanye nemisinga yokuvuza elawulwa kakhulu (yize izinselele zokuvuza nazo zanda esikalini se-nanometer encane).
2. Ukusebenza okuphezulu: Ubuningi be-transistor obukhulu buvumela ukwanda kwemvamisa, ama-core engeziwe, kanye nezinqolobane ezinkulu ngaphandle kokukhulisa usayizi we-chip.
Umthelela kuma-smartphone uzwakala emazingeni ozimele emidlalo azinzile, ukucutshungulwa kwezithombe okusheshayo kokubala, ukuqoshwa kwevidiyo ngaphandle kokushisa kakhulu, kanye nezici ze-AI ezifana nokuqashelwa kwezinto, ukuhumusha ungaxhunyiwe ku-inthanethi, noma ukucutshungulwa kwezwi okusebenza ngendlela ephendulayo.
Inqubo Yokukhiqiza: Kusukela ku-Wafer kuya ku-Chip
Ukukhiqizwa kwama-chip e-3nm kuqala nge-wafer ye-silicon, ishidi eliyindilinga elikhulu elisebenza njenge-"canvas" yokwakha ama-transistors. Kule wafer, ifektri ye-semiconductor (eyenziwe ngendwangu) yakha isakhiwo se-transistor ngezinyathelo zokucubungula ezingamakhulu kuya ezinkulungwaneni. Izinyathelo ezibalulekile zifaka:
– Ukufakwa: Ukwengeza ungqimba oluncane lwezinto (isib. i-oxide, i-nitride, noma insimbi) ku-wafer.
– I-Lithography: Ukuphrinta amaphethini wesekethe kuma-wafer kusetshenziswa ukukhanya kanye ne-photoresist (izinto ezizwela ukukhanya).
– Ukuqopha: Ukuklwebha izingxenye ezithile ukuze kwakhiwe isakhiwo esihle.
– Ukufakelwa kwama-ion: Ukudubula ama-ion ukuze kwakhiwe izakhiwo ze-elekthronikhi ezindaweni ezithile (ukusebenzisa izidakamizwa).
– I-Metology kanye nokuhlolwa: Ukulinganisa ukujiya kanye nokuhambisana kwephethini ngokunemba kwe-nanometer.
– Ukuhlela (i-CMP): Ukusibekela ubuso be-wafer ukuze ungqimba olulandelayo lukwazi ukwakheka ngokunembile.
Uma amaphethini e-transistor kanye ne-interconnect eseqediwe, i-wafer iyasikwa ibe yizicucu, bese ipakishwa ngaphambi kokuba yenziwe i-SoC efakwe ebhodini lesekhethi le-smartphone.
Indima ye-EUV: Isihluthulelo se-3nm
Esinye sezici ezinkulu ezenza i-node ye-3nm isebenzise i-lithography ye-EUV (Extreme Ultraviolet). I-EUV isebenza ngamaza okukhanya amafushane kakhulu (cishe angu-13,5 nm), okuvumela ukuphrinta kwephethini okucolekile kakhulu kune-lithography yesizukulwane sangaphambilini (DUV).
Ngaphandle kwe-EUV, ukwenza amaphethini ama-transistors amancane kakhulu kudinga indlela eyinkimbinkimbi kakhulu "yokwenza amaphethini amaningi": ungqimba olulodwa lwephethini kumele luphrintwe ngokuphindaphindiwe, okwandisa isikhathi sokukhiqiza, ingozi yeziphambeko, kanye nezindleko. I-EUV iqeda lesi sidingo sokuphindaphinda, yize imishini ye-EUV ngokwayo ibiza kakhulu, iyinkimbinkimbi, futhi idinga izindawo ezihlanzekile kakhulu kanye ne-vacuum ephezulu ukuze ukukhanya kwe-EUV kusebenze kahle.
Isakhiwo se-Transistor: I-FinFET kanye nokuvela kwe-GAAFET
Sekuyiminyaka eminingi imboni ithembele kuma-transistors e-FinFET, lapho isiteshi se-transistor sibunjwe khona “njenge-fin” eqondile ukuze kuthuthukiswe ukulawulwa kukagesi futhi kuncishiswe ukuvuza. Kodwa-ke, ngosayizi omncane kakhulu, ama-FinFET aqala ukusondela emikhawulweni yawo yokukhula.
Ku-node ye-3nm, abanye abakhiqizi sebeqala ukwamukela izakhiwo ezintsha ze-transistor njenge-GAAFET (i-Gate-All-Around FET). Ku-GAAFET, isango le-transistor lizungeza isiteshi kuzo zonke izinhlangothi, linikeza ukulawula kwamanje okungcono. Lokhu kuthuthukisa ukusebenza kahle kanye nokusebenza, ikakhulukazi uma kukhulunywa ngama-voltage okusebenza kanye nokunciphisa ukuvuza. Ukuqaliswa kungathatha isimo sama-nanosheet noma ama-nanowires, kuye ngobuchwepheshe bokukhiqiza.
Lokhu kuguquka ekwakhiweni kwe-transistor kungenye yezizathu ezenza ukuthi i-node engu-3nm ingabi nje "ukunciphisa usayizi," kodwa kube ushintsho olukhulu endleleni ama-transistor akhiwa ngayo.
Izinselele Eziyinhloko: Izindleko, Isivuno, kanye Nokushisa
Nakuba kubukeka kuthembisa, ukwenziwa kwe-3nm kubhekene nezinselele ezinkulu:
1. Izindleko zokukhiqiza ziyanda
Imishini ye-lithography ye-EUV, izinto ezikhethekile, kanye nobunzima benqubo kwenza izindleko nge-wafer ngayinye kanye nezindleko zokuthuthukiswa ziphezulu kakhulu. Lokhu kuchaza ukuthi kungani ama-chip e-3nm evame ukuvela kuqala kumadivayisi aphezulu.
2. Ukwehluleka kokukhiqiza kanye nokukhiqiza
Uma ama-transistor elukhuni kakhulu, kulapho i-chip isheshe izwele khona ezinhlayiyeni zothuli ezincane noma ekushintsheni kwenqubo. Isivuno esiphansi sisho ukuthi ama-chip amaningi ayahluleka nge-wafer ngayinye, okwandisa izindleko nge-chip ngayinye edlula ikhwalithi.
3. Ukuphathwa kokushisa
Nakuba ama-chip asebenza kahle kakhulu, anamandla kakhulu angakhiqiza ukushisa okukhulu ngaphansi kwemithwalo ephezulu. Ama-smartphone asadinga umklamo omuhle wokupholisa (igumbi lomhwamuko, ishidi le-graphite, kanye nokwenza ngcono isofthiwe) ukuze kugcinwe ukusebenza okuzinzile.
4. Ukuklama nokuqinisekisa kuya kuba nzima kakhulu
Kuma-node amancane kakhulu, imiphumela ebonakalayo efana nokwehluka kwenqubo, ukumelana kokuxhumana, kanye nezimo ze-quantum iba sobala kakhulu. Abaklami be-Chip kumele basebenzise amathuluzi e-EDA athuthukile futhi benze ukulingisa okujulile.
Umthelela Ezicini Ze-Smartphone
Ama-chip e-3nm awagcini nje ngokubala amaphuzu okulinganisa. Ukusebenza kahle okwandisiwe kanye nokuminyana kwama-transistor kuthinta izici ezahlukahlukene:
– Izithombe ezisheshayo zokubala: I-ISP enamandla kakhulu ingahlanganisa ozimele abaningi, ithuthukise i-HDR, inciphise umsindo, futhi ithuthukise imininingwane.
– Ukuthuthukiswa kwe-AI kudivayisi: I-NPU enamandla kakhulu ivumela izici ze-AI ukuthi zisebenze endaweni ngaphandle kokuthumela idatha efwini, okuthuthukisa ubumfihlo nokunciphisa ukubambezeleka.
– Imidlalo kanye nehluzo: Ama-GPU angakhuphula ukucaca, anikeze ukulandelela imisebe okulinganiselwe (kumapulatifomu athile), futhi anikeze amazinga ozimele azinzile.
– Ukuxhumana: Ukuhlanganiswa kwezingxenye zemodemu ne-RF kungasebenza kahle kakhulu, yize abathengisi abaningi besahlukanisa imodemu ukuze bavumelane nokuguquguquka komklamo.
Ikusasa Ngemva kwe-3nm
I-node ye-3nm ayisona isiphetho. Imboni isivele ikhuluma nge-2nm nangale kwayo, ngokusetshenziswa okwengeziwe kwama-GAAFET, izinto ezintsha, kanye namasu okupakisha athuthukile njenge-chiplets noma i-3D stacking. Kodwa-ke, kuma-smartphone, ibhalansi phakathi kwezindleko, ukusebenza kahle, kanye nokushisa kuzohlala kuyisici esibalulekile. Kungenzeka ukuthi ngeke kube yi-node enquma umphumela, kodwa futhi nokwakhiwa kwe-CPU/GPU, ukulungiswa kwe-AI, ukuphathwa kwamandla, kanye nokuhlanganiswa kwesistimu iyonke.
Isiphetho
