TSMC kuleli sonto ukwazi isigaba esisha sobuchwepheshe be-lithographic, esiqokiwe i-N6. Ukukhululwa kwabezindaba kuthe lesi sigaba se-lithography sizolethwa esigabeni sokukhiqizwa kwengozi ngekota yokuqala ka-2020, kodwa kuphela umbhalo wengqungquthela yokubika yekota ye-TSMC okwenze kwaba nokwenzeka ukufunda imininingwane emisha mayelana nesikhathi sokuthuthukiswa kwe-TSMC. okuthiwa ubuchwepheshe be-6-nm.
Kufanele kukhunjulwe ukuthi i-TSMC isivele ikhiqiza ngobuningi imikhiqizo eminingi ye-7-nm - engxenyeni yokugcina yakha i-22% yemali engenayo yenkampani. Ngokwezibikezelo zokuphatha ze-TSMC, kulo nyaka izinqubo zobuchwepheshe ze-N7 kanye ne-N7+ zizobala okungenani u-25% wemali engenayo. Isizukulwane sesibili sobuchwepheshe benqubo ye-7nm (N7+) sibandakanya ukusetshenziswa okwandisiwe kwe-ultra-hard ultraviolet (EUV) lithography. Ngesikhathi esifanayo, njengoba abamele i-TSMC begcizelela, kwakuyisipiliyoni esitholwe ngesikhathi sokuqaliswa kwenqubo yezobuchwepheshe ye-N7+ eyavumela inkampani ukuthi inikeze amakhasimende inqubo yezobuchwepheshe ye-N6, elandela ngokuphelele i-N7 design ecosystem. Lokhu kuvumela abathuthukisi ukuthi bashintshe ukusuka ku-N7 noma ku-N7+ baye ku-N6 ngesikhathi esifushane ngangokunokwenzeka nangezindleko zezinto ezibonakalayo. U-CEO u-CC Wei uze wazwakalisa ukuzethemba engqungqutheleni yekota ukuthi wonke amakhasimende e-TSMC asebenzisa inqubo ye-7nm azoshintshela kubuchwepheshe be-6nm. Ngaphambilini, esimweni esifanayo, ukhulume ngokulungela "cishe bonke" abasebenzisi be-TSMC ye-7nm inqubo yobuchwepheshe ukuthuthela kubuchwepheshe benqubo ye-5nm.
Kungaba kuhle ukuchaza ukuthi yiziphi izinzuzo ezinikezwa ubuchwepheshe be-5nm process (N5) owenziwe yi-TSMC. Njengoba u-Xi Xi Wei avuma, mayelana nomjikelezo wokuphila, i-N5 izoba enye "ehlala isikhathi eside" emlandweni wenkampani. Ngesikhathi esifanayo, kusukela ekubukeni komthuthukisi, kuzohluka kakhulu kubuchwepheshe benqubo ye-6-nm, ngakho-ke ukuguqulwa kwezindinganiso zokuklama ze-5-nm kuzodinga umzamo omkhulu. Isibonelo, uma ubuchwepheshe benqubo ye-6nm buhlinzeka ngokunyuka kwe-7% ku-transistor density uma kuqhathaniswa ne-18nm, khona-ke umehluko phakathi kuka-7nm no-5nm uzofika ku-80%. Ngakolunye uhlangothi, ukwanda kwejubane le-transistor ngeke kudlule i-15%, ngakho-ke i-thesis mayelana nokunciphisa isenzo "somthetho kaMoore" iqinisekisiwe kuleli cala.
Konke lokhu akuvimbeli inhloko ye-TSMC ukuthi ithi ubuchwepheshe benqubo ye-N5 “buzoqhudelana kakhulu embonini.” Ngosizo lwayo, inkampani ayilindele nje kuphela ukwandisa isabelo sayo semakethe ezingxenyeni ezikhona, kodwa futhi nokuheha amakhasimende amasha. Esimweni sokwazi ubuchwepheshe benqubo ye-5nm, amathemba akhethekile abekwe engxenyeni yezixazululo ze-high-performance computing (HPC). Manje akubalanga ngaphezu kwama-29% emali engenayo ye-TSMC, futhi u-47% wemali engenayo uvela ezingxenyeni zama-smartphone. Ngokuhamba kwesikhathi, isabelo sengxenye ye-HPC kuzofanele sikhule, nakuba abathuthukisi bamaphrosesa ama-smartphones bezozimisela ukwazi izindinganiso ezintsha ze-lithographic. Ukuthuthukiswa kwamanethiwekhi esizukulwane se-5G kuzoba esinye sezizathu zokukhula kwemali engenayo eminyakeni ezayo, inkampani ikholelwa.
Ekugcineni, i-CEO ye-TSMC yaqinisekisa ukuqala kokukhiqizwa kwe-serial kusetshenziswa ubuchwepheshe benqubo ye-N7+ kusetshenziswa i-EUV lithography. Izinga lesivuno lemikhiqizo efanelekile esebenzisa le nqubo yobuchwepheshe liqhathaniswa nobuchwepheshe besizukulwane sokuqala se-7nm. Ukwethulwa kwe-EUV, ngokusho kuka-Xi Xi Wei, akukwazi ukuhlinzeka ngembuyiselo yezomnotho ngokushesha - kuyilapho izindleko ziphezulu kakhulu, kodwa ngokushesha nje lapho ukukhiqizwa “kudlondlobala”, izindleko zokukhiqiza zizoqala ukwehla ngesivinini esijwayelekile eminyakeni yamuva nje.
