Hauv cov thev naus laus zis niaj hnub no, kev tswj hwm qhov hluav taws xob tsis sib xws yog qhov tseem ceeb uas cuam tshuam ncaj qha rau cov qauv me me ntawm cov zaj duab xis nyias, qhov ceev, kev ntxhov siab sab hauv, thiab lub zog nplaum. Txawm hais tias nyob rau hauv cov txheej txheem tawv, cov yeeb yaj kiab zoo nkauj, lossis cov txheej txheem kho qhov muag, kev tswj hwm kom zoo ntawm qhov hluav taws xob tsis sib xws ntawm cov substrate tsis yog tsuas yog hloov kho cov plasma dynamics, tab sis kuj txhim kho kev ua haujlwm thiab kev ntseeg siab ntawm cov yeeb yaj kiab tshwm sim.
No.1 Kev Tswj Xyuas Qhov Hluav Taws Xob Bias Yog Dab Tsi?
Kev tswj hwm qhov hluav taws xob tsis sib xwshais txog cov txheej txheem ntawm kev siv lub zog tsis zoo rau lub substrate thaum lub sijhawm tso dej, ua rau nws qis dua li cov plasma nyob ib puag ncig. Cov txheej txheem no siv dav hauv PVD (Physical Vapor Deposition) cov txheej txheem, tshwj xeeb tshaj yog hauv magnetron sputtering, ion plating, thiab cathodic arc deposition systems.
Qhov kev cuam tshuam ntawm lub substrate tuaj yeem siv tau los ntawm DC (Direct Current), MF (Mid-Frequency), lossis RF (Radio Frequency) fais fab mov. Nws lub luag haujlwm tseem ceeb yog ua kom cov ions zoo hauv plasma mus rau qhov chaw ntawm lub substrate sai dua, ua rau muaj kev tawm tsam ion uas txhawb nqa cov yam ntxwv zoo ntawm kev loj hlob ntawm zaj duab xis.
No.2 Yuav ua li cas Bias Voltage cuam tshuam rau cov khoom ntawm zaj duab xis
Lub hauv paus tseem ceeb ntawm kev tswj hwm qhov hluav taws xob tsis sib xws yog nyob rau hauv kev hloov kho qhov kev loj hlob ntawm zaj duab xis los ntawm lub zog ntawm cov ions nkag. Nws qhov cuam tshuam tau pom tseeb hauv ntau yam tseem ceeb:
Kev Ua Kom Nto:
Ib qho kev cuam tshuam tsis zoo uas tsim nyog yuav ua rau lub zog kinetic ntawm cov ions uas tuaj txog ntawm lub substrate nce ntxiv, txhawb kev txav mus los ntawm qhov chaw thiab kev hloov pauv ntawm cov adatoms. Qhov no ua rau cov zaj duab xis denser nrog kev txhim kho corrosion, hardness, thiab hnav tsis kam.
Kev Tswj Xyuas Kev Nyuaj Siab:
Kev siv ion bombardment kuj ua rau muaj kev ntxhov siab seem hauv zaj duab xis. Kev cuam tshuam ntau dhau tuaj yeem ua rau muaj kev ntxhov siab compressive, uas ua rau tawg lossis delamination. Yog li ntawd, cov qib kev cuam tshuam zoo tshaj plaws yuav tsum tau xaiv ua tib zoo raws li cov khoom siv zaj duab xis, hom substrate, thiab tuab txheej.
Kev Txhim Kho Kev Sib Txuas:
Qhov hluav taws xob bias ua rau muaj kev sib cuam tshuam ntawm cov interfacial los ntawm kev txhawb nqa kev sib xyaw ntawm cov txheej txheem lossis tsim cov interfaces graded, yog li txhim kho cov zaj duab xis-rau-substrate adhesion - tshwj xeeb tshaj yog qhov tseem ceeb rau cov txheej txheem tawv lossis cov qauv ntau txheej.
Kev Tiv Thaiv Cov Khoom Me Me thiab Kev Ua Kom Nto du:
Kev ntxub ntxaug tsim nyog tuaj yeem tiv thaiv kev koom ua ke ntawm cov khoom me me thiab txo qhov roughness ntawm qhov chaw, yog li txo qhov poob ntawm cov yeeb yaj kiab optical thiab txhim kho qhov zoo ntawm qhov chaw.
No.3 Hom Kev Tswj Xyuas Kev Ntshai
DC Bias: Feem ntau siv rau cov khoom siv hluav taws xob conductive, muab kev tswj yooj yim thiab teb sai. Feem ntau siv rau hauv cov txheej txheem kho kom zoo nkauj thiab cov txheej txheem tawv.
RF Bias: Zoo tagnrho rau cov khoom siv uas tsis ua hluav taws xob xws li iav, ceramics, thiab polymers. Muaj kev sib raug zoo ntawm cov khoom siv dav dav tab sis xav tau kev koom ua ke ntawm lub kaw lus thiab kev kho cov txheej txheem ntau dua.
Pulsed Bias: Yuav siv cov periodic bias pulses, sib npaug ntawm tus nqi deposition thiab lub zog ion. Zoo rau cov txheej txheem kub qis lossis cov qauv geometries nyuaj.
Tsis tas li ntawd xwb, qee lub tshuab ua haujlwm siab heev siv kev tswj hwm kev cuam tshuam kaw-loop, uas saib xyuas cov yam ntxwv ntawm plasma thiab kev cuam tshuam tam sim no hauv lub sijhawm tiag tiag kom tswj tau qhov ruaj khov ntawm cov txheej txheem thiab xyuas kom meej tias cov txheej txheem sib xws thoob plaws cov pawg.
