Slicing yog cov txheej txheem ntawm kev faib cov semiconductor wafer rau hauv ib lub nti, feem ntau ntawm lub hauv paus ntawm wafer tau ua tiav cov txheej txheem dhau los thiab kev ntsuas hluav taws xob. Nyob rau tib lub sij hawm, raws li thawj kauj ruam ntawm semiconductor ntim, qhov zoo ntawm scribing yuav ncaj qha cuam tshuam rau qhov kawg kev ntseeg ntawm cov khoom ntim. Sib tsoo log txiav yog ib qho ntawm feem ntau siv txiav txoj kev tam sim no. Cov hniav tsim los ntawm pob zeb diamond hais thiab nplaum yog tig los ntawm kev kub ceev los ntawm kev sib txuas ntawm spindle, sib tsoo ib leeg nrog cov khoom yuav tsum tau ua, thiab noj ntawm ib qho ceev kom faib cov wafer rau hauv cov chips ywj siab. Qhov tsis xws luag xws li tawg los ntawm qhov seem ntawm kev ntxhov siab thiab kev puas tsuaj rau cov txheej txheem yog cov teeb meem tseem ceeb txwv txoj kev loj hlob ntawm kev sib tsoo log.
Nrog rau txoj kev loj hlob sai ntawm semiconductor integrated circuits, cov kev xav tau tshiab ntawm kev ua haujlwm zoo thiab kev ua haujlwm tau zoo tau ua ke nrog cov yam ntxwv ntawm cov khoom sib txawv, los ntawm kev xaiv cov cuab yeej scribing, cov txheej txheem parameter optimization thiab scribing txoj kev txhim kho, thiab lwm yam, cov cuab yeej txiav. ib qho kev txhim kho. Nyob rau hauv lub ntsej muag ntawm txoj kev loj hlob ntawm kev sib txawv ntawm cov cuab yeej, tshwj xeeb tshaj yog nyob rau hauv txoj kev loj hlob ntawm tsis sib cuag scribing yuav tsum xws li ultra-thin wafers thiab MEMS wafers uas muaj cov qauv txav, sib tsoo log scribing tsis tuaj yeem txaus siab. Laser txiav tuaj yeem zam qhov teeb meem ntawm kev sib tsoo log tawg, thiab tib lub sijhawm me me thiab MEMS chips, qhia txog qhov tseem ceeb ntawm qhov zoo, daim ntawv no feem ntau yuav tham txog cov ntawv thov tseem ceeb ntawm laser tsis pom kev txiav thiab laser ablation txiav ob hom kev txiav. txoj kev.
Laser invisible txiav tshuab
Invisible txiav tshuab yog ib lub tshuab uas tsom ib tug translucent wavelength laser beam los ntawm ib tug optical tsom iav rau sab hauv ntawm lub wafer, tsim ib tug pib taw tes rau segmentation nyob rau hauv lub wafer, uas yog, hloov txheej, thiab ces siv sab nraud quab yuam rau lub wafer. muab faib rau hauv ib qho kev ywj pheej nti. Yog li ntawd, invisible txiav tshuab feem ntau suav nrog ob txheej txheem: laser txiav thiab nti sib cais. Cov txheej txheem laser txiav, raws li cov khoom siv sib txawv, xaiv qhov sib xws wavelength laser los ntawm txoj kev kho qhov muag tshwj xeeb, tsom rau sab hauv ntawm lub wafer los tsim cov txheej txheem hloov kho, cov txheej txheem hloov kho hauv tib lub sijhawm, yuav tsim ib qho tawg taw tes rau qhov zoo thiab qhov tsis zoo ntawm lub wafer. Rau qee qhov tuab ntawm lub wafer, lub laser yuav tsum tau tsom ob peb zaug ntawm qhov sib txawv focal qhov tob kom luam theej duab sab hauv ntawm lub wafer, kom cov txheej txheem hloov kho txuas nrog rau ib leeg, thiab thaum kawg tsim tag nrho cov txheej txheem hloov kho kom haum rau segmentation, uas. yog ib kauj ruam tseem ceeb los txhawb kev sib cais chip.
Raws li kev tsim cov txheej txheem hloov kho, cov txheej txheem nti sib cais yog ua kom cov txheej txheem hloov pauv khiav ntawm qhov chaw thiab hauv qab ntawm lub wafer, thiab tom qab ntawd muab cais ua ib qho kev ywj pheej nti los ntawm lwm lub zog xws li kev sib cais, los yog ncaj qha los ntawm kev sib kis. thiab sib cais.
Laser ablation txiav tshuab
Laser ablation txiav yog siv high-zog pulsed laser, tom qab lub optical system collimation thiab tsom, tsim ntawm siab zog ceev, beam chaw me me ntawm tsuas yog micron laser beam, ua rau ntawm qhov chaw ntawm lub workpiece, thiaj li hais tias irradiated cheeb tsam. hauv zos melting, gasification, kom cov scribing interchannel cov ntaub ntawv tshem tawm, thiab thaum kawg ua tiav grooving los yog ncaj scribing.
Laser ablation txiav yuav siv sij hawm qhov kub thiab txias raws li lub mechanism ntawm kev txiav txim, thiab nyob rau hauv lub ablation ntug yuav tsim ib lub tshav kub-cuam tshuam cheeb tsam nrog lub phenomenon ntawm nquag recasting ntawm cov txheej txheem cov khoom. Yuav ua li cas tswj qhov luaj li cas ntawm tshav kub-cuam tshuam cheeb tsam yog lub ntsiab txoj kev kom paub txoj kev loj hlob ntawm laser txiav nyob rau hauv lub semiconductor kev lag luam. Cov khoom siv laser thiab kho qhov muag raug xaiv thiab teeb tsa raws li kev nqus cov yam ntxwv ntawm cov khoom ua tiav rau qhov sib txawv wavelengths ntawm laser. Ntawm lawv, cov mem tes dav yog qhov tseem ceeb tsis zoo cuam tshuam rau kev txiav zoo, qhov tseeb yog hais txog lub sijhawm ntawm txhua lub laser ib leeg mem tes, nyob rau hauv cov ntaub ntawv ntawm tib lub zog thiab zaus, qhov me me ntawm pulse dav, lub sij hawm luv luv ntawm lub laser. thiab cov khoom ua tiav, qhov me me ntawm thaj chaw tshav kub cuam tshuam, uas tuaj yeem txo qhov tsis zoo ntawm cov txheej txheem ablation ntawm ntug. Tsis tas li ntawd, kev xaiv ntawm lasers kuj yuav tsum tau coj mus rau hauv tus account lub efficiency thiab zoo, feem ntau lub luv luv lub laser wavelength, qhov me me ua rau tshav kub cuam tshuam cheeb tsam, tab sis lub laser ceev yog qeeb thiab efficiency yog tsawg.
Tam sim no, muaj ob lub ntsiab ntawm laser txiav technologies siv nyob rau hauv semiconductor wafer txiav, uas yog laser stealth txiav thiab laser ablation txiav. Ob lub thev naus laus zis muaj lawv tus kheej cov yam ntxwv, thiab ob qho tib si qhia qhov zoo uas cov tsoos sib tsoo tsis tuaj yeem sib phim. Nrog rau kev txhim kho txuas ntxiv ntawm laser thev naus laus zis thiab kev loj hlob ntawm cov cuab yeej muaj feem xyuam, laser txiav yuav tuav tau ntau txoj haujlwm tseem ceeb hauv kev lag luam ntawm semiconductor wafer txiav.
