Cov khoom siv ntawm cov txheej txheem membrane cuam tshuam los ntawm adhesion, kev ntxhov siab, kev sib sau ntom ntom, thiab lwm yam. Los ntawm kev sib raug zoo ntawm cov txheej txheem membrane thiab txheej txheem txheej txheem, nws tuaj yeem pom tias yog tias peb xav txhim kho lub zog ntawm cov txheej txheem membrane, peb yuav tsum tsom mus rau cov txheej txheem hauv qab no:
(1) nqus tsev vacuum. Lub tshuab nqus tsev ntawm kev ua yeeb yaj kiab yog qhov pom tseeb heev. Feem ntau ntawm cov ntsuas kev ua tau zoo ntawm cov txheej txheem zaj duab xis yog nyob ntawm qib nqus. Feem ntau, raws li lub tshuab nqus tsev kawm ntawv nce, cov zaj duab xis aggregation ceev nce, lub firmness nce, cov qauv ntawm zaj duab xis yog zoo dua, cov tshuaj muaj pes tsawg leeg ua ntshiab, tab sis nyob rau tib lub sij hawm qhov kev nyuaj siab kuj nce.
(2) Deposition tus nqi. Txhim kho tus nqi deposition tsis tsuas yog siv tau los txhim kho cov evaporation tus nqi, uas yog, nce evaporation qhov kub thiab txias mus kom ze, kuj tseem siv tau los ua kom cov evaporation qhov chaw mus kom ze, tab sis kev siv cov evaporation qhov chaw kom qhov kub thiab txias ntawm txoj kev muaj nws drawbacks: ua rau lub membrane txheej kev nyuaj siab loj heev; film-forming gas yog yooj yim rau decompose. Yog li qee zaum nce qhov chaw evaporation ntau dua li txhawm rau txhim kho qhov evaporation qhov kub thiab txias yog qhov zoo dua.
(3) kub substrate. Ua kom lub substrate kub yog haum rau adsorption ntawm lub substrate nto ntawm cov roj molecules ntxiv kom tshem tawm, nce lub substrate thiab lub binding quab yuam ntawm lub deposited molecules: nyob rau tib lub sij hawm yuav txhawb kev hloov dua siab tshiab ntawm lub cev adsorption rau tshuaj adsorption, txhim khu kev sib cuam tshuam ntawm molecules, kom lub membrane txheej txheej txheem nruj. Piv txwv li, mg, membrane, sab hauv cua sov rau 250 ~ ℃ Npaj ua kom muaj zog ntxiv, tab sis cov cua sov ntau dua yuav ua rau lub cev ua kom zoo dua yuav ua rau lub ntsej muag kub siab dhau lawm.
(4) Ion foob pob tawg. Ion bombardment muaj qhov cuam tshuam rau kev tsim ntawm cohesive nto, nto roughness, oxidation thiab aggregation ceev. Lub foob pob ua ntej txheej tuaj yeem ntxuav qhov chaw thiab ua kom cov adhesion; lub foob pob tom qab txheej tuaj yeem txhim kho cov zaj duab xis txheej aggregation ceev, thiab lwm yam, yog li ua kom lub zog thiab hardness.
(5) Substrate ntxuav. Substrate tu txoj kev tsis tsim nyog los yog tsis huv, nyob rau hauv lub substrate residual impurities los yog tu tus neeg saib xyuas, ces ua kom muaj kuab paug tshiab, nyob rau hauv lub txheej ntawm sib txawv cohesion tej yam kev mob thiab adhesion, cuam tshuam rau thawj txheej ntawm cov yam ntxwv thiab optical thickness, tab sis kuj ua rau cov zaj duab xis txheej yog ib qho yooj yim mus tawm ntawm lub substrate, yog li hloov cov yam ntxwv ntawm cov zaj duab xis txheej.
