Cov Khoom Siv Hluav Taws Xob Kub Kub Kub
Kev kho cua sov feem ntau suav nrog oxidation, diffusion thiab annealing txheej txheem.Oxidation yog ib qho txheej txheem ntxiv uas silicon wafers muab tso rau hauv lub qhov cub kub kub thiab cov pa oxygen ntxiv los ua rau lawv tsim silica rau saum npoo ntawm wafer.Diffusion yog txav cov tshuaj los ntawm qhov chaw siab concentration mus rau thaj tsam qis qis los ntawm molecular thermal txav, thiab cov txheej txheem diffusion tuaj yeem siv los ua cov tshuaj dope tshwj xeeb hauv silicon substrate, yog li hloov cov conductivity ntawm semiconductors.
