Dab tsi yog qhov kev puas tsuaj ntawm ESD rau cov khoom siv hluav taws xob
ESD kev puas tsuaj rau cov khoom siv hluav taws xob ESD kev puas tsuaj rau cov khoom siv hluav taws xob, txawm hais tias ESD ncaj qha tso cov khoom siv hluav taws xob los yog cov khoom siv hluav taws xob ncaj qha, cov khoom siv hluav taws xob tuaj yeem puas. Nws tuaj yeem tsis tsuas yog ua rau tsis ua hauj lwm ntawm cov cuab yeej ua haujlwm nkaus xwb, tab sis kuj ua rau muaj peev xwm ua tsis tiav ntawm cov cuab yeej ua haujlwm.
1. Sudden tsis ua hauj lwm
Sudden tsis ua hauj lwm txhais tau hais tias thaum ib qho khoom siv hluav taws xob raug rau ib puag ncig ESD, qhov ntsuas hluav taws xob yuav hloov pauv tau thiab nws txoj haujlwm yuav ploj mus. ESD tej zaum yuav ua rau cov hlau yaj thiab ua rau luv luv lossis tawg ntawm cov txheej txheem rwb thaiv tsev, thiab lwm yam, ua rau muaj kev puas tsuaj mus tas li rau cov khoom siv hluav taws xob. Xws li kev ua tsis tiav tuaj yeem kuaj pom hauv cov khoom tiav ua ntej xa khoom. Raws li kev txheeb cais, ntawm cov khoom siv hluav taws xob puas tsuaj los ntawm hluav taws xob zoo li qub, kev ua tsis tiav tam sim ntawd suav txog li 10% ntawm tag nrho cov kev ua tsis tiav.
Ib qho hluav taws xob muaj zog yuav ua rau lub rooj vag oxide txheej ntawm MOS cov khoom siv hluav taws xob tawg thiab ua rau lub cuab yeej ua tsis tiav. Feem ntau, lub rooj vag oxide zaj duab xis thickness ntawm MOS li yog nyob rau ntawm qhov kev txiav txim ntawm 1 (T7 m). Thaum lub Circuit Court tsim tsis tau kev tiv thaiv kev ntsuas, txawm tias ib tug tuab thiab pinhole-free high-zoo oxide txheej yuav tawg down nyob rau hauv ib tug electrostatic voltage ntawm 100 V. Rau Rau circuits nrog tiv thaiv kev ntsuas, txawm hais tias lub neej puas voltage tej zaum yuav ntau dua li 100 V, qhov hluav taws xob ntawm cov khoom siv hluav taws xob txaus ntshai tuaj yeem yog ntau txhiab volts lossis txawm tias kaum tawm txhiab volts. Yog li ntawd, cov nyhuv tawg ntawm high-voltage electrostatic teb tseem yog ib qho teeb meem loj rau MOS circuits. Tsis tas li ntawd, qhov hluav taws xob hluav taws xob hluav taws xob hluav taws xob siab kuj tseem tuaj yeem ua rau dielectric puas ntawm cov kab hluav taws xob sib txuas lossis cov dielectric tawg ntawm cov hlau hlau hlau, ua rau tsis ua haujlwm hauv Circuit Court.
2. Muaj peev xwm ua tsis tiav
Tej zaum tsis ua hauj lwm txhais tau hais tias thaum lub cuab yeej raug rau ESD ib puag ncig, nws yuav ua rau ib nrab degradation ntawm lub cuab yeej' qhov kev ua tau zoo, tab sis ib ntus tsis cuam tshuam rau nws txoj haujlwm zoo. Txawm li cas los xij, lub neej kev pab cuam ntawm lub cuab yeej yog luv heev. Qhov kev puas tsuaj no yog cumulative. Raws li tus naj npawb ntawm ESD pulses tau ntsib nce ntxiv, qhov hluav taws xob hluav taws xob puas tsuaj hluav taws xob ntawm lub cuab yeej tau maj mam txo, lossis qhov tsis zoo ntawm cov cuab yeej maj mam deteriorate. Raws li kev txheeb cais, qhov muaj peev xwm ua tsis tiav suav rau 90% ntawm tag nrho cov lej ntawm ESD ua tsis tiav hauv cov khoom siv hluav taws xob. Yog li ntawd, lub peev xwm ua tsis tiav ntawm cov khoom siv hluav taws xob muaj teeb meem ntau dua.
