Laser Ua: Ib Lub Sijhawm Tshiab Rau Chip Manufacturing

Laser Ua: Ib Lub Sijhawm Tshiab rau Chip Manufacturing
Raws li cov khoom siv hluav taws xob txuas ntxiv me me thiab nce hauv kev ua haujlwm, cov txheej txheem tsim khoom tom qab lawv yuav tsum tau hloov zuj zus mus ntxiv txhawm rau ua kom tau raws li qhov xav tau ntawm kev ua tau zoo, precision, thiab yooj. Ib qho kev vam meej tshaj plaws hauv kev tsim cov chips yog kev siv laser ua tshuab, uas tau ua pov thawj tias yog ib qho cuab yeej muaj zog rau kev tsim cov txheej txheem nyuaj nrog kev ceev thiab raug tsis tau pom dua.
Dab tsi yog laser ua, thiab yog vim li cas nws thiaj li muaj nuj nqis rau chip manufacturing? Ntawm nws cov theem pib tshaj plaws, kev ua laser suav nrog kev siv lub teeb tsom ntawm lub teeb kom tshem tawm cov khoom ntawm lub substrate. Cov txheej txheem no tuaj yeem siv los tsim cov yam ntxwv me me xws li cov channel, vias, thiab qhov hauv cov khoom siv semiconductor. Los ntawm kev siv lasers es tsis txhob siv cov txheej txheem tsim khoom xws li tshuaj etching lossis milling, cov tuam ntxhab tuaj yeem ua tiav ntau dua qhov tseeb thiab yooj yim hauv kev tsim ntawm lawv cov chips.
Muaj ntau ntau hom lasers uas yuav siv tau rau chip manufacturing, txhua tus nrog lawv tus kheej zoo thiab kev siv. Piv txwv li, ultraviolet (UV) lasers feem ntau yog siv rau drilling qhov me me los yog trenches nyob rau hauv silicon los yog lwm yam semiconductor cov ntaub ntawv, thaum femtosecond lasers (uas ua hauj lwm ntawm incredibly luv luv mem tes ntev) yuav siv tau los tsim complex 3D qauv nyob rau hauv ib cov khoom.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev ua laser yog lub peev xwm los tsim cov chips nrog cov sij hawm txo qis heev. Cov txheej txheem ib txwm muaj xws li photolithography tuaj yeem siv sijhawm ntau lub lis piam lossis ntau lub hlis los ua kom tiav, thaum kev ua laser tuaj yeem ua tiav hauv ib teev lossis hnub. Qhov no ua rau nws yooj yim dua rau cov tuam txhab lag luam kom nrawm nrawm ntawm lawv cov qauv tsim thiab tsim cov qauv rau kev sim.
Ib cag ntawm lawv qhov ceev thiab qhov tseeb, lasers kuj muaj lwm yam txiaj ntsig rau kev tsim chip. Piv txwv li, los ntawm kev siv laser ua, manufacturers tuaj yeem tsim cov yam ntxwv uas tsis tuaj yeem ua tiav siv lwm txoj hauv kev. Lawv kuj tuaj yeem tsim cov yam ntxwv zoo heev nrog qhov sib piv siab (lub ntsiab lus siab heev nrog lub hauv paus nqaim heev) uas tuaj yeem yog qhov tseem ceeb rau qee hom chip tsim.
Nyob rau tib lub sijhawm, tseem muaj qee qhov kev sib tw thiab kev txwv cuam tshuam nrog kev ua laser. Piv txwv li, lub tshav kub kub uas tsim los ntawm lub teeb laser tuaj yeem ua rau cov khoom nyob ib puag ncig puas tsuaj yog tias cov txheej txheem tsis ua tib zoo tswj. Tsis tas li ntawd, tus nqi ntawm cov khoom siv laser tuaj yeem txwv tsis pub siab rau cov tuam txhab me me lossis pib ua lag luam.
Txawm hais tias cov kev cov nyom no, kev ua laser yog sai dhau los ua cov cuab yeej tseem ceeb rau chip manufacturers thoob ntiaj teb. Raws li cov khoom siv hluav taws xob txuas ntxiv tau me dua thiab siab dua, qhov kev thov rau qhov tseeb, hloov tau yooj yim, thiab nrawm hauv kev tsim cov chips tsuas yog txuas ntxiv mus. Nrog nws qhov tsis sib xws qhov tseeb thiab ntau yam, kev ua laser yog npaj los ua lub luag haujlwm tseem ceeb hauv kev nce qib ntawm cov khoom siv hluav taws xob rau xyoo tom ntej.
