Cov ntaub ntawv photoresist muaj txiaj ntsig zoo rau kev tsim cov khoom xws li cov chips computer thiab lwm yam khoom siv hluav taws xob. Photolithography yog cov txheej txheem ntawm kev siv cov ntaub ntawv tshwj xeeb no. Semixlab cov khoom siv photoresist thiab Yuav Siv Li Cas Hauv Kev Lag Luam Semiconductor Cia Peb Saib Ze Dua.
Ntau yam khoom siv uas rhiab rau lub teeb hu ua cov khoom siv photoresist. Lawv siv los tso cai rau cov qauv kom raug xa mus rau silicon wafers hauv kev lag luam semiconductor. Thaum koj ci lub teeb rau cov khoom no, lawv teb kom lawv yaj lossis nyob twj ywm tsis hloov pauv hauv qee cov tshuaj lom neeg. Qhov no tso cai rau cov chaw tsim khoom ua cov qauv nyuaj rau cov khoom siv semiconductor nrog kev ua kom raug.
Photolithography yog ib txoj kev siv rau kev tsim cov qauv ntawm silicon wafers. Qhov no ua raws li kev nthuav tawm ntawm photoresist hla lub wafer. Tom qab ntawd lawv raug ci ntsa iab nrog lub teeb los ntawm lub ntsej muag, uas dais cov qauv xav tau. Cov khoom hauv qab uas raug nthuav tawm lossis tsis raug nthuav tawm ntawm photoresist yuav, nyob ntawm hom photoresist siv, yuav yaj lossis nyob hauv qhov khov kho. Tom qab kev txhim kho thiab tshem tawm cov cheeb tsam tsis tau nthuav tawm, cov qauv tseem nyob ntawm silicon wafer.
Peb, zoo thiab tsis zoo yog ob hom Semixlab cov khoom siv photoresist arfThaum cov photoresist zoo raug rau lub teeb, nws yuav yaj tau hauv cov tshuaj developer, thaum cov photoresists tsis zoo tseem tsis raug cuam tshuam. Cov photoresists zoo feem ntau siv rau kev ua qauv zoo, thiab cov photoresists tsis zoo yooj yim rau kev tuav thiab zoo hauv kev nplaum.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov ntaub ntawv photoresist yog lub peev xwm los tsim cov qauv meej heev. Qhov ntawd tso cai rau cov chaw tsim khoom tsim cov khoom siv hluav taws xob me dua, muaj zog dua. Cov ntaub ntawv Photoresist kuj pheej yig thiab yooj yim siv, thiab yog li ntawd siv dav hauv kev lag luam semiconductor.
Cov ntaub ntawv Photoresist tau tsim kho sai heev nyob rau xyoo tas los no nrog ntau qhov kev tsim kho tshiab uas tau ua rau cov txheej txheem ntawm photolithography zoo dua thiab sai dua. Thiab cov polymers tshiab tau tsim uas yuav rhiab heev rau lub teeb. Qhov ntawd txhais tau tias lawv tuaj yeem raug nthuav tawm sai dua, uas yog qhov sai dua (thiab yog li ntawd pheej yig dua) ua.
Tsis tas li ntawd xwb, kev tsim kho tshiab hauv nanotechnology tau ua rau Semixlab zoo dua photoresist cov ntaub ntawv uas tuav tau zoo thiab tiv taus ib puag ncig. Cov khoom tshiab no siv tau los tsim cov khoom siv hluav taws xob uas me dua, nrawm dua thiab muaj zog dua li cov uas siv niaj hnub no.
