Photolithography feem ntau yog siv los tsim lub computer chips. Thaum tsim cov computer chips, cov khoom siv substrate yog tiv thaiv wafer ntawm silicon. Cov txheej txheem no tso cai rau ntau pua lub chips ib txhij ua rau ntawm ib qho silicon wafer.
photolithography ua li cas?
Kev yees duab siv peb cov txheej txheem txheej txheem los hloov tus qauv ntawm lub npog ntsej muag mus rau wafer: coat, txhim kho, nthuav tawm. Cov qauv yog pauv mus rau hauv lub wafer txheej txheej thaum lub sij hawm tom ntej. Qee zaum, tus qauv tiv thaiv kuj tuaj yeem siv los txhais cov qauv rau cov yeeb yaj kiab nyias nyias.
photolithography yog dab tsi thiab nws ua haujlwm li cas?
Photolithography yog txheej txheem txheej txheem uas cov txheej txheem photosensitive polymer tau xaiv raug rau lub teeb los ntawm lub npog ntsej muag, tawm hauv cov duab latent hauv cov polymer uas tuaj yeem xaiv tau yaj kom muab cov qauv. nkag mus rau hauv ib qho substrate.
photolithography yog dab tsi thiab nws siv li cas los siv cov transistors?
Nws siv lub teeb hloov pauv tus qauv geometric los ntawm photomask (tseem hu ua lub ntsej muag kho qhov muag) rau cov duab (uas yog, lub teeb-sensitive) tshuaj photoresist ntawm substrate. … Nws muab cov kev tswj xyuas meej ntawm cov duab thiab qhov loj ntawm cov khoom uas nws tsim thiab tuaj yeem tsim cov qauv ntawm tag nrho cov nqi-zoo.
Vim li cas thiaj hu ua photolithography?
Semiconductor Lithography(Photolithography) - Txheej txheem txheej txheem . Kev tsim khoom ntawm kev sib koom ua ke (IC) yuav tsum muaj ntau yam txheej txheem ntawm lub cev thiab tshuaj lom neeg ua rau ntawm cov khoom siv hluav taws xob (piv txwv li, silicon) substrate. … Lo lus lithography los ntawm Greek lithos, lub ntsiab lus pob zeb, thiab graphia, lub ntsiab lus sau.
