Ngokusho kwemithombo yezimboni, umkhiqizi omkhulu wenkontileka wama-semiconductors, i-TSMC yaqala ukuthola ubunzima ngokuthunyelwa ngesikhathi kwemikhiqizo ye-silicon ekhiqizwa kusetshenziswa ubuchwepheshe be-7nm. Ngenxa yokwanda kwesidingo kanye nokushoda kwezinto zokusetshenziswa, isikhathi sokulinda sokuthi amakhasimende agcwalise ama-oda awo okukhiqiza angu-7nm manje sesiphindeke kathathu kuya cishe ezinyangeni eziyisithupha. Ekugcineni, lokhu kungase kuthinte ibhizinisi labakhiqizi abaningi, kuhlanganise ne-AMD, lapho i-TSMC ikhiqiza khona amaphrosesa esimanje emindeni ye-EPYC ne-Ryzen, kanye nama-chips e-Radeon graphics.
Ukwanda okuwumphumela wesidingo semikhiqizo ye-TSMC ye-7nm kuchazwe kahle. Inani elandayo lozakwethu be-TSMC lishintshela ekusetshenzisweni kwezinqubo zesimanje ze-lithographic, okuholela ekulayishweni okuminyene kwemigqa yokukhiqiza. Ukwandiswa kwamandla kuhlotshaniswa nokutshalwa kwezimali okukhulu kwezimali, ngakho-ke ngeke kwenziwe ngokushesha.
Ekugcineni, konke lokhu kwaholela ekwakhekeni kolayini bamakhasimende embonini ye-semiconductor: ngokusho kwe-Digitimes, uma ngaphambili amakhasimende ayelinda ngokwesilinganiso cishe izinyanga ezimbili ukuze ama-oda awo aqedwe, manje isikhathi sokulinda sifinyelela ezinyangeni eziyisithupha. Lokhu, kudinga izinkampani ezisebenzisa izinsizakalo ze-TSMC ukuthi zibikezele isidingo sesikhathi eside futhi zenze ama-oda kusenesikhathi. Amaphutha enziwe ekuhleleni kulesi simo angaphenduka kalula abe yizinkinga ezinkulu ezingathinta noma ngubani, kuhlanganisa ne-AMD.
Ukuze kube nobulungisa, kufanele kuqashelwe ukuthi i-TSMC izama ukwanelisa izicelo ezivamile ezivela kumakhasimende avamile kuqala, futhi ukubambezeleka ekulethweni kuthinta ngokuyinhloko lawo makhasimende adinga ukunikezwa okungeziwe noma abashintshela kubuchwepheshe be-7nm besuka kwezinye izinqubo zobuchwepheshe. Ngakho-ke, nakuba ama-Ryzen 3000 processors kanye nama-Navi GPUs enziwa e-TSMC kusetshenziswa ubuchwepheshe benqubo ye-7nm “eyinkinga”, i-AMD, kungakhathaliseki ukuthi yini, izoqhubeka nokuthola imikhiqizo ye-semiconductor ngaphansi kwezinkontileka eziqinile eziphethwe ngaphambilini.
Ngesikhathi esifanayo, lokhu akuqinisekisi ukuthi i-AMD ngeke ibe nezinkinga esikhathini esizayo lapho idinga ukwandisa umthamo wokukhiqiza wama-chips angu-7nm. Futhi isimo esinjalo sizovela ngokushesha noma kamuva, ngoba isidingo semikhiqizo ye-AMD siyanda, futhi ngaphandle kwalokho, izinhlelo ezisheshayo zenkampani zihlanganisa ukukhululwa kwenani lemikhiqizo emisha, okumele kusetshenziswe ubuchwepheshe be-TSMC be-7nm FinFET. Lokhu kufaka phakathi, ngokwesibonelo, ukukhululwa kwe-Threadripper yesizukulwane sesithathu, i-Ryzen entsha yeselula kanye ne-Navy 12/14 yama-graphics chips amakhadi wevidiyo aphezulu nasezingeni lokungena.
Ngaphezu kwalokho, inkinga ingase ibe yimbi nakakhulu ngenxa yokukhishwa kwe-iPhone 11 entsha, iphrosesa ye-A13 Bionic nayo ekhiqizwa kusetshenziswa ubuchwepheshe be-7-nm ezikhungweni ze-TSMC. Ngaphambilini i-AMD kudingeke ukuthi ilungise uhlelo lwayo loku-oda ama-chips ayo angu-7nm ukuze ingaqhudelani ngomthamo wokukhiqiza ne-Apple. Lokhu kungenzeka futhi, ikakhulukazi ngenxa yentshisekelo ephezulu ku-iPhone 11, isidingo saso sokuqala eseqe izibikezelo zokuqala.
Ngokungeziwe kuma-chips e-AMD, imikhiqizo evela kwabanye abakhiqizi abasebenzisa ubuchwepheshe benqubo ye-TSMC ye-7nm nayo isengozini. Ikakhulukazi, amaphrosesa eselula e-Qualcomm Snapdragon 855, asetshenziswa kuma-smartphones amaningi, i-Xilinx Versal arrays yamasango ahlelekayo, ama-chips amaningi e-Huawei eselula, kanye ne-Mediatek system-on-chip elindeleke ngo-2020, akhiqizwa kusetshenziswa lobu buchwepheshe.
Ngaleso sikhathi, i-TSMC ngokwayo ayinaso isithakazelo ekukhuphuleni ukushoda okuvela kwemikhiqizo engu-7-nm, ngoba uma kungenjalo amakhasimende angaqala ukubheka kwabanye osonkontileka, kulokhu i-Samsung. Ngakho-ke, ungaqiniseka ukuthi yonke imizamo engenzeka izokwenziwa ukwanelisa izicelo zamakhasimende ngesikhathi. Inkampani yaseTaiwan kubikwa ukuthi ihlose ukwaba imali eyengeziwe ukuze kuthuthukiswe ubuchwepheshe bayo obuphambili. Asethembe ukuthi inkinga yokushoda izoxazululeka ngokushesha.
