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.
Vim li cas thiaj hu ua photolithography?
Semiconductor Lithography (Photolithography) - Cov 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.
Vim li cas lithography tseem ceeb?
Lithography yog cov txheej txheem ntawm kev hloov cov qauv ntawm cov duab geometric hauv daim npog ntsej muag rau cov txheej nyias nyias ntawm cov khoom siv hluav taws xob (hu ua tiv thaiv) npog qhov chaw ntawm cov khoom siv hluav taws xob. Daim duab 5.1 qhia txog schematically cov txheej txheem lithographic ua haujlwm hauv IC fabrication.
Qhov twg yog txoj kev siv dav tshaj plaws hauv txoj kev lithographic?
Opticallithographyyog cov txheej txheem photon-raws li kev tsim cov duab rau hauv photosensitive emulsion (photoresist) coated rau substrate xws li silicon wafer. Nws yog cov txheej txheem lithography uas tau siv dav tshaj plaws hauv kev tsim cov khoom ntim siab ntawm nano-electronics los ntawm kev lag luam semiconductor.
