Kev faib tawm ntawm cov hluav taws xob zoo li qub
Qhov txaus ntshai ntawm hluav taws xob zoo li qub nyob rau hauv electrostatic tawm (ESD). ESD kav tsuas yog milliseconds, nrog cov mem tes tam sim no thiab lub zog nruab nrab, txaus los txhawm rau cov khoom siv hluav taws xob lossis tshuab hluav taws xob.
Cov yam ntxwv muaj koob meej ntawm ESD kev puas tsuaj yog nws Randomness, tsis muaj kev lees paub, thiab teeb meem hauv kev kuaj pom. Hauv kev lag luam niaj hnub, tshwj xeeb tshaj yog nyob rau hauv {1} teev cov khoom siv hluav taws xob ntau lawm, tsis muaj tib neeg lub ntsej muag thiab yog qhov nyuaj rau ntes tau. Qhov tshwm sim ntawm ESD kev puas tsuaj rau cov khoom siv yog qhov nyuaj tawg thiab muag muag. Kev ua haujlwm nyuaj ua rau muaj cua sov sab hauv ntawm ib kauj ruam hauv ib kauj ruam, ua haujlwm saum npoo av, thiab qhov tsis txaus siab ua kom tiav thiab tsis ua tiav ntawm kev sib xyaw Circuit Court. Mos tawg tuaj yeem ua rau muaj kev ua phem lossis tsis muaj kev puas tsuaj, yog li tsim cov kev puas tsuaj uas nyuaj rau kev soj ntsuam thaum kawg kev kuaj xyuas. Thaum siv, kev puas tsuaj los ntawm cov hluav taws xob zoo li qub rau hauv lub nroog yuav ua rau muaj kev hloov pauv ntawm cov chaw nyob, thiab txo lub neej vim muaj kev hloov pauv ntawm qhov kub thiab txias, thiab kev tiv thaiv ntau zaus, thiab ntsuas hluav taws xob, tsis muaj kev ua haujlwm ib txwm muaj. Yog hais tias lub qhov ntswg puas yog rau ib qho tseem ceeb tswj hwm, xws li kev tswj hwm network, tsis siv neeg lub sijhawm tswj hwm hluav taws xob, lossis siv ntau yam kev tswj hwm hluav taws xob, qhov kev puas tsuaj hauv kev puas tsuaj tuaj yeem tsis tuaj yeem ua rau tsis tau. Cov peev xwm kev puas tsuaj tuaj yeem ua tau txaus ntshai ntau dua, ua rau muaj kev cuam tshuam loj dua lossis tsis ncaj. Cov ntaub ntawv qhia tau hais tias 90% ntawm ESD - Qhov kev ua tsis taus khoom puas yog lub peev xwm muag puas tsuaj, thiab 10% yog tam sim ntawd tsis ua haujlwm.
Tsis tas li ntawd, hluav taws xob Pulses tsim thaum lub sijhawm hluav taws xob sib txuas lus nrog ntau yam: Kev siv hluav taws xob ntau ntxiv rau cov pa hluav taws xob (KHz)
Qee tus neeg ntseeg tias cov laug cam sib xyaw nrog ESD kev tiv thaiv kab ke yog tsis muaj zog rau electrostatic puas. Txawm li cas los xij, thaum kev tiv thaiv kev teeb hluav taws xob muab qee cov kev tiv thaiv, txawm tias muaj hluav taws xob hauv kev tiv thaiv ntau txhiab tus neeg lub cev lossis cov chaw ua haujlwm. Txhua qhov kev sib xyaw ua ke yog rhiab rau cov hluav taws xob tawm; Qhov sib txawv tsuas yog cov lus dag nyob hauv qhov ntsuas ntsuas hluav taws xob lawv tuaj yeem tiv taus.
Cov hluav taws xob zoo li qub thiab kev phom sij ntawm semiconductor thiab i yog cov kab ntau lawm:
1. Taug kev qeeb ntawm cov khaub ncaws huv thaum hnav cov khaub ncaws nylon thiab yas}}}}}} Cov khau tuaj yeem tsim cov hluav taws xob zoo li ntawm 7-8kv ntawm lub cev.
2. Thaum ib tug crystal cab kuj ua los ntawm cov ntaub pua rooj fiberglass hla cov ntsiav tshuaj polyethylenepoop, nws tuaj yeem yooj yim tsim kom muaj qhov hluav taws xob zoo li qub.
3. On wafer sib dhos cov kab: Wafer lub zog hluav taws xob tuaj yeem ncav cuag 5kv, wafer chav loading thawv 35kv, quartz
4. Hauv Photolithography chav, yas plag tsev ncav cuag 500-1000V; Hauv cov hlau ntxaij maim partitions, 500-1000000000000; Hauv cov chav sib txawv, cov plag tsev yas ncav cuag 500-1500V; Yas Phab Ntsa Taus Ua Npua Ncauj Xeeb Kwv yees li 700v; Thiab cov hlau rooj zaum cov rooj zaum kom ncav cuag 500000V.
