Lub tshuab nqus tsev twj ua lub luag haujlwm tseem ceeb hauv kev tsim khoom semiconductor. Tshwj xeeb, lawv muaj cov ntawv thov tseem ceeb hauv qab no:
1. Tsim kom muaj lub tshuab nqus tsev ruaj khov: Hauv kev tsim khoom semiconductor, ntau cov txheej txheem yuav tsum muaj lub tshuab nqus tsev ib puag ncig los tiv thaiv gaseous impurities los ntawm kev paug cov khoom. Semiconductor lub tshuab nqus tsev twj tuaj yeem ua tau zoo tshem tawm cov roj av tsim tawm thaum lub sijhawm ua haujlwm, yog li tswj hwm lub tshuab nqus tsev hauv cov txheej txheem chamber thiab ua kom cov khoom zoo.
2. Tshem tawm cov pa phem: Thaum lub sij hawm tsim khoom semiconductor, cov pa phem rau tib neeg thiab ib puag ncig qee zaum tsim tawm. Lub tshuab nqus tsev nqus tau sai sai tshem tawm cov pa phem no, ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab tiv thaiv ib puag ncig.
3. Muab cov txheej txheem ruaj khov: Los ntawm kev tsis tu ncua thiab ruaj khov muab lub tshuab nqus tsev ib puag ncig, lub tshuab nqus tsev semiconductor muab cov kev txhawb nqa tsim nyog rau cov txheej txheem me me hauv kev tsim khoom, yog li ua kom cov khoom sib xws thiab kev ntseeg tau.
