AbakwaSamsung Electronics basaqhubeka nokucwila kubuchwepheshe benqubo yesigaba se-10 nm. Kulokhu, ezinyangeni eziyi-16 nje kuqale ukukhiqizwa ngobuningi benkumbulo ye-DDR4 kusetshenziswa ubuchwepheshe benqubo yesizukulwane sesibili se-10nm class (1y-nm), umkhiqizi waseNingizimu Korea uqedele ukuthuthukiswa kwenkumbulo ye-DDR4 efa esebenzisa isizukulwane sesithathu sekilasi le-10 nm ( 1z-nm) inqubo yobuchwepheshe. Okubalulekile ukuthi inqubo yesigaba sesithathu se-10nm isasebenzisa izikena ze-lithography ze-193nm futhi ayinciki kuzikena ze-EUV ezisebenza kancane. Lokhu kusho ukuthi ukushintshela ekukhiqizweni kwenkumbulo ngobuningi kusetshenziswa ubuchwepheshe bakamuva benqubo ye-1z-nm kuzoshesha futhi ngaphandle kwezindleko ezinkulu zezimali zokuhlomisa kabusha imigqa.
Inkampani izoqala ukukhiqiza ngobuningi be-8-Gbit DDR4 chips isebenzisa ubuchwepheshe benqubo ye-1z-nm yekilasi le-10 nm engxenyeni yesibili yalo nyaka. Njengoba bekuyinjwayelo kusukela ekushintsheni kubuchwepheshe benqubo ye-20nm, abakwaSamsung abavezi imininingwane eqondile yobuchwepheshe benqubo. Kucatshangwa ukuthi inqubo yenkampani yekilasi le-1x-nm 10-nm ihlangabezana namazinga angu-18 nm, inqubo ye-1y-nm ihlangabezana namazinga angu-17- noma angu-16-nm, futhi i-1z-nm yakamuva ihlangabezana nezindinganiso ezingu-16- noma 15-nm, futhi mhlawumbe kuze kufike ku-13 nm. Kunoma ikuphi, ukunciphisa isikali senqubo yezobuchwepheshe kuphinde kwandisa isivuno samakristalu avela ku-wafer eyodwa, njengoba i-Samsung ivuma, ngo-20%. Ngokuzayo, lokhu kuzovumela inkampani ukuthi ithengise inkumbulo entsha eshibhile noma ngenani elingcono kuze kube yilapho izimbangi zithola imiphumela efanayo ekukhiqizeni. Kodwa-ke, kuyethusa kancane ukuthi i-Samsung ayikwazanga ukwakha ikristalu ye-1z-nm 16 Gbit DDR4. Lokhu kungase kubonise ukulindela ukwanda kwamazinga okungasebenzi ekukhiqizeni.
Isebenzisa isizukulwane sesithathu sobuchwepheshe benqubo yekilasi le-10nm, inkampani izoba ngowokuqala ukukhiqiza inkumbulo yeseva nenkumbulo yama-PC aphezulu. Ngokuzayo, ubuchwepheshe benqubo yekilasi le-1z-nm 10nm buzoshintshwa ukuze kukhiqizwe inkumbulo ye-DDR5, LPDDR5 kanye ne-GDDR6. Amaseva, amadivaysi eselula kanye nezithombe zizokwazi ukusebenzisa ngokugcwele inkumbulo esheshayo nencane elambele inkumbulo, okuzokwenziwa lula ukushintshela kumazinga okukhiqiza amancane.
