Imec unveils zoo tagnrho transistor rau 2nm txheej txheem thev naus laus zis

Raws li peb paub, kev hloov pauv mus rau 3 nm txheej txheem thev naus laus zis yuav nrog kev hloov pauv mus rau qhov tshiab transistor architecture. Hauv Samsung cov ntsiab lus, piv txwv li, cov no yuav yog MBCFET (Multi Choj Channel FET) transistors, nyob rau hauv uas transistor channel yuav zoo li ob peb txoj kab nyob saum ib sab hauv daim ntawv nanopages, ncig ntawm txhua sab los ntawm lub rooj vag (kom paub meej ntxiv. , saib archive ntawm peb cov xov xwm rau lub Peb Hlis 14).

Raws li cov neeg tsim khoom los ntawm Belgian centre Imec, qhov no yog qhov kev vam meej, tab sis tsis zoo, transistor qauv siv ntsug FinFET rooj vag. Qhov zoo tshaj plaws rau cov txheej txheem thev naus laus zis nrog cov khoom ntsuas tsawg dua 3 nm txawv transistor qauv, uas tau thov los ntawm Belgians.

Imec tau tsim lub transistor nrog cov nplooj ntawv sib cais lossis Forksheet. Cov no yog tib lub nanopages ntsug li transistor raws, tab sis sib cais los ntawm ntsug dielectric. Nyob rau ib sab ntawm lub dielectric, ib tug transistor nrog ib tug n-channel yog tsim, nyob rau lwm yam, nrog ib tug p-channel. Thiab ob leeg ntawm lawv yog ib puag ncig los ntawm ib qho kev kaw nyob rau hauv daim ntawv ntawm ib txoj kab ntsug.

Txo qhov ntawm-chip nrug ntawm transistors nrog cov conductivities sib txawv yog lwm qhov kev sib tw loj rau kev txo qis dua. TCAD simulations tau lees paub tias qhov sib cais-nplooj transistor yuav muab 20 feem pua ​​​​txo hauv cheeb tsam tuag. Feem ntau, tus tshiab transistor architecture yuav txo tus qauv logic cell qhov siab mus rau 4,3 lem. Lub xovtooj yuav ua tau yooj yim dua, uas tseem siv tau rau kev tsim khoom ntawm SRAM nco cell.

Ib qho kev hloov pauv yooj yim los ntawm nanopage transistor mus rau qhov sib cais nanopage transistor yuav muab 10% nce hauv kev ua tau zoo thaum tswj kev noj, lossis 24% txo kev noj yam tsis muaj kev ua tau zoo. Kev simulations rau 2nm txheej txheem tau pom tias SRAM cell siv cov nanopages sib cais yuav muab qhov sib xyaw ua ke txo qis thiab kev txhim kho kev ua tau zoo txog li 30% nrog p- thiab n-hluav taws xob sib nrug mus txog 8 nm.
