Tungsten Ion Implantation Cheebtsam Description
Tungsten yog cov hlau tawv nrog lub ntsej muag ci thiab silvery dawb. Nws tiv taus oxidation thiab tawm tsam los ntawm acids thiab alkalis. Nws yog cov hlau loj thiab muaj qhov siab tshaj plaws melting point ntawm txhua yam hlau. Lub npe tshuaj ntawm tungsten yog wolfram, sawv cev los ntawm W. Nws tus lej atomic yog 74 thiab nws yog nyob rau hauv kev hloov pauv hlau qeb, lub sijhawm 6 ntawm lub sijhawm.
Ion implantation yog cov txheej txheem tseem ceeb uas tau siv dav hauv kev tsim cov khoom siv hluav taws xob semiconductor, xov hlau, thiab cov ntaub ntawv tshawb fawb. Nws yog cov txheej txheem kub qis los ntawm qhov uas cov ions ntawm ib lub ntsiab lus tau nrawm rau hauv lub hom phiaj, yog li hloov lub cev, tshuaj lossis hluav taws xob ntawm lub hom phiaj.
Ion implanter yog cov cuab yeej tseem ceeb hauv kev ua kev sib xyaw ua ke. Thaum ion beams raug tua rau saum npoo ntawm semi-conductor thiab tso, cov cab kuj concentration thiab conduction hom hloov. Tus tswv ntawm nws qhov kev hloov kho zoo heev, ion implantation yog dav siv hauv cov khoom siv semi conducting, hlau, ceramics, high-molecular polymer, thiab lwm yam.
Ion implantation yog qhov tseem ceeb hauv kev ua kom muaj kev sib koom ua ke loj heev (IC). Lub Cheebtsam ntawm ion implantation feem ntau yog ua los ntawm TZM, molybdenum thiab tungsten vim hais tias cov ntaub ntawv no yuav ua tau zoo nyob rau hauv hnyav ib puag ncig vim lawv corrosion kuj, lub zog, thiab siab thermal conductivity. Qhov tseem ceeb tshaj plaws ntawm lub tshuab implanter yog txoj kab nqaj uas cov khoom sib koom ua ke. Ntawm no, cov ions yog generated, concentrated, ceev, thiab tsom mus rau lub wafer.
