Cov khoom ua tsov rog nyuaj ntawm Tebchaws Meskas thiab Tuam Tshoj tseem nce ntxiv, ua rau muaj kev cuam tshuam tseem ceeb ntawm semiconductor muab cov khoom siv semiconductor. Cov khoom siv ntshuam thiab cov khoom siv tsawg dua xws li kev tsav tsheb ceev kom muaj kev xav tau rau cov thev naus laus zis thiab hauv qab. Qhov kev thov no los ntawm tag nrho cov kev lag luam txuas, suav nrog cov kev xav tau rau cov ntsiab lus tseem ceeb hauv cov saw xeem.
Qhov kev xeem soj ntsuam kev lag luam tuaj yeem faib ua semiconductor, PCB, ICT Kev kuaj mob online thiab lwm ntu raws li ntawv thov. Ntawm lawv, semiconductor xeem xeem muaj cov kev sib cav ua rau lawv cov khoom lag luam nyuaj, thiab cov hluav taws xob ntau thiab tshuab ua kom tau. Tau ntev heev, lub khw no tau xav ntau ntawm ob peb hom neeg txawv teb xws li yokowo los ntawm Nyij Pooj, ECT ntawm Tebchaws Asmeskas thiab Idi. Qhov no ua rau cov lus nug tseem ceeb: Tuam Tshoj cov semiconductor ntim thiab ntsuas txuas hauv qhov chaw tseem ceeb, vim li cas thiaj li yog kev sojntsuam me me, tseem tab tom "caj dab" ntawm kev teeb meem?
Kev ntsuam xyuas cov kev sim ua ntu zus, yog qhov loj me me tab sis lub luag haujlwm hnyav tab sis lub luag haujlwm ntawm precision hluav taws xob. Txawm hais tias cov tsos ntawm kev sib txawv siv, tab sis feem ntau muaj ib rab koob, koob pas nrig (lossis lwm yam kev sib tw muaj lub caij nplooj ntoo hlav) thiab lwm yam kev sib tw, qhov loj tag nrho ntau dua li ntawm qib micron. Mas siv nyob rau hauv semiconductor chip tsim pov thawj, wafer kuaj, raws li tus choj ntawm cov cim taw tes los kuaj lub nti kom pom cov cim kev ua tiav ntau yam kev ua tau zoo.
Nws tsis yooj yim rau txheej txheem microstructures ntawm ib teev ntawm cov mov tsuas yog ib qho teeb meem me me (tsis yooj yim dua li khoov), thiab lub neej zoo (ntev kev pab cuam). Cov txheej txheem dav dav, xws li cov photolithography ua ke nrog cov tshuaj etching lossis precision stamping thiab molding rau micron-theem kev ua kom pom kev, feem ntau ntsib cov teeb meem ntawm cov txheej txheem nyuaj thiab cov nqi siab. Tshwj xeeb tshaj yog thaum ua cov ntaub ntawv hardness siab lossis cov ntaub ntawv tshwj xeeb xws li cov khoom sib tiv toj, thiab lwm yam ntawm cov khoom siv vim muaj kev ntxhov siab, thiab kev tswj hwm ntawm cov duab ntawm cov ntxeev. Cov kev tsis zoo no ncaj qha cuam tshuam qhov tseeb thiab kev ntseeg tau ntawm kev sojntsuam ntawm kev soj ntsuam, tseem ceeb heev rau cov txiaj ntsig thiab tswj hwm tus qauv kev lag luam semiconductor.
Tom qab ntawd tsis muaj lwm txoj kev? Ntawm tam sim no, femtosecond laser ua lag luam technology qhia tau muaj peev xwm loj los daws cov teeb meem saum toj no. Noj {{{{{{{{}}}}}} microflabrication ntawm cov ntaub ntawv nyuaj.
Hemtosecond laser ua li cas?
1. "Kev ua kom muaj kev puas tsuaj uas tsis muaj kev puas tsuaj: lub zog ua haujlwm ntawm cov khoom siv thaum lub sijhawm ua haujlwm luv luv thiab tawm tsam nws tawm, nrog yuav luag tsis muaj cua sov-cuam tshuam cheeb tsam. Qhov no txhais tau tias kev txiav siab zoo "txias" tuaj yeem ua tiav tsis muaj cov txheej txheem deformations, txawm hais tias nws yog tungsten, lossis lwm yam hlau, ceramics, polymers thiab lwm yam ntaub ntawv. Qhov no yog qhov tseem ceeb rau kev tswj cov khoom qub ntawm kev sojntsuam cov khoom siv, kom muaj kev ruaj khov hluav taws xob conductivity thiab ntev heev neeg kho lub neej thaum sim.
2, qhov kawg precorabrication: femtosecond laser laser laser tuaj yeem tsom mus rau theem kev tswj hwm siab, tuaj yeem ua tiav ± 1μm lossis txawm tias yuav ua tau zoo dua. Tsis yog tiv tauj laser kev ua lag luam tsis yog txwv los ntawm cov duab ntawm cov qauv nqaj, muaj peev xwm tsim tau rau cov khoom lag luam nqaj thiab cov qauv me me, ntau hom tsiaj tsim qauv.
3, kev txiav zoo heev: sojntsuam cov chaw sib chwv zoo nkauj thiab ntug zoo rau qhov kev ruaj ntseg ntawm kev sib cuag thiab kev sim ua neej. Femtosecond laser txiav yog du, zoo tig (tsis muaj taper lossis tswj taper), roughness taper), roughness to ra tsawg dua los yog sib npaug}. 1μm, yuav luag tsis muaj burr, tsis muaj slag. Qhov no tsis tsuas yog txhim kho kev tiv tauj ruaj khov thiab kuj tau tshem tawm qhov xav tau ntawm cov txheej txheem kev kho mob ntxiv xws li kev deburring thiab ua polishing.
Saib tom ntej, cov khoom siv Industrial ntawm femtosecond laser laser thev naus laus zis txuas ntxiv kom tob. Qhov kev tsim kho thev naus laus zis no muab cov kev tsim kho tshiab ntawm cov lag luam tseem ceeb, thiab yuav tsum tau ua qhov tseem ceeb tshaj plaws ntawm cov lag luam txawv teb chaws thiab txhim kho kev tswj hwm ywj pheej ntawm cov khoom tseem ceeb ntawm cov khoom tseem ceeb ntawm cov khoom tseem ceeb ntawm cov khoom tseem ceeb ntawm cov khoom tseem ceeb ntawm cov khoom tseem ceeb. Qhov no yuav ua lub luag haujlwm zoo hauv kev txhawb nqa lub resilieting thiab kev sib tw ntawm Tuam Tshoj cov semiconductor cov kev lag luam kev lag luam.
