Kev yees duab siv peb cov txheej txheem yooj yim hloov pauv tus qauv ntawm lub npog ntsej muag mus rau wafer: lub tsho tiv no, 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 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.
Vim li cas thiaj siv photolithography?
Photolithography yog ib txoj hauv kev tseem ceeb tshaj plaws thiab yooj yim tshaj plaws ntawm microfabrication, thiab yog siv los tsim cov qauv ntxaws hauv cov khoom. Hauv cov qauv no, cov duab lossis cov qauv tuaj yeem raug etched los ntawm kev xaiv raug ntawm lub teeb rhiab polymer rau lub teeb ultraviolet.
Vim li cas UV lub teeb siv hauv photolithography?
Photolithography tso cai 3D encapsulation ntawm cov hlwb hauv hydrogels los ntawm kev sib txuas cov cell-muaj prepolymer nyob rau hauv UV teeb. Lub photomask yog siv kom tau cov qauv uas xav tau [88].
Yuav ua li cas rau photolithography?
Feem ntau, cov txheej txheem photolithography yuav tsum peb cov ntaub ntawv yooj yim, lub teeb ci, daim npog ntsej muag, thiab photoresist. Photoresist, cov khoom siv photosensitive,muaj ob hom, zoo thiab tsis zoo. Qhov zoo photoresist ua ntau soluble tom qab raug rau lub teeb.
