1. Taw qhia
Xaiv cov khoom siv semiconductor photolithography yog ib qho ntawm cov peev txheej tseem ceeb tshaj plaws uas lub chaw microfabrication yuav puas tau ua. Cov cuab yeej raug cuam tshuam ua haujlwm ntawm micron thiab nanometer tolerances, qhov twg microscopic deviations nyob rau hauv theem positioning, optical illumination, los yog tsom stability ncaj qha txiav txim cov txheej txheem yields.
Txawm li cas los xij, cov thawj coj hauv chav huv tau nkag siab txog qhov tseem ceeb ntawm kev lag luam muaj tseeb: xaiv cov khoom tsim nyog yog ib qho tseem ceeb xws li xaiv lub tshuab specifications.
Lub cuab yeej photolithography tsis yog ib qho khoom siv rau cov neeg siv khoom siv uas ua haujlwm tawm ntawm lub thawv yam tsis muaj kev sib koom tes txuas ntxiv. Nws yog ib qho nyuaj optomechanical thiab software system uas yuav tsum tau ua kom huv huv kev sib koom ua ke, daim ntawv qhia kev tsim nyog, kho qhov muag kho qhov muag, kev tiv thaiv kev saib xyuas, thiab ntau xyoo ntawm kev txhawb nqa khoom seem.
Kev koom tes nrog ib tus neeg ua haujlwm tsis muaj kev paub lossis tus neeg muag khoom tsis ua haujlwm feem ntau ua rau lub sijhawm ncua kev teeb tsa, qhov tsis raug kho qhov muag tsis pom, tsis muaj cov khoom seem, thiab lub limtiam ntawm lub sijhawm tsis muaj kev tu ncua. Hloov pauv, koom tes nrog cov chaw tsim khoom tsim khoom nrog rau kev ua haujlwm ntawm semiconductor daim ntawv thov kev tsim kho kom ntseeg tau tias koj qhov kev cuam tshuam tau muab qhov tseeb qhov tseem ceeb (CD) sib xws, cov txheej txheem kev vam khom - rau- txheej txheej txheej, thiab kev ua haujlwm ruaj khov ua haujlwm ntev tshaj li kaum - mus rau - kaum tsib - xyoo ua haujlwm qab ntug.
Ua ntej tshaj tawm daim ntawv xaj yuav khoom, pawg neeg yuav khoom hauv chav huv yuav tsum saib dhau ntawm daim ntawv tshaj tawm kev lag luam zoo nkauj thiab nruj me ntsis ntsuas qhov tob ntawm kev tsim khoom, kev ntseeg siab ntawm kev tsim khoom, thiab tom qab -muag kev tsim kho ntawm cov khoom lag luam yav tom ntej.
2. Ntsuas Cov Kws Tshaj Lij Ua Haujlwm
Semiconductor microfabrication spans heev ntau haiv neeg substrate ntaub ntawv, ntaus ntawv architectures, thiab txheej txheem txwv. Lub peev xwm photolithography cov khoom lag luam yuav tsum muaj cov txheej txheem semiconductor engineering kev txawj ntse ntau dua li kev paub txog kev muag khoom.
Nkag siab txog koj cov txheej txheem tshwj xeeb yuav tsum muaj:
Thaum lub sij hawm pib kev sib tham, soj ntsuam seb tus neeg muag khoom lub tuam txhab pab pawg neeg tuav koj cov cuab yeej tshwj xeeb physics:
