Hauv cov khoom siv semiconductor twg, lub txaj granite yog siv dav tshaj plaws?

Lub txaj granite yog ib qho tseem ceeb hauv ntau yam khoom siv semiconductor. Raws li cov khoom siv ruaj khov thiab khov kho, granite siv dav dav ua lub hauv paus rau cov khoom siv ua semiconductor. Nws yog tus cwj pwm los ntawm nws cov coefficient nthuav dav thermal qis, kev ruaj khov siab, thiab cov khoom siv kho tshuab zoo heev. Vim yog cov yam ntxwv no, lub txaj granite feem ntau siv rau hauv peb hom khoom siv semiconductor sib txawv - cov khoom siv metrology, cov khoom siv lithography, thiab cov khoom siv tshuaj xyuas.

Cov khoom siv Metrology siv los ntsuas thiab ntes cov qhov loj me tseem ceeb ntawm cov khoom siv semiconductor. Nws ua lub luag haujlwm tseem ceeb hauv kev tswj hwm qhov zoo thiab kev sib xws ntawm cov txheej txheem tsim khoom semiconductor. Cov khoom siv Metrology suav nrog cov cuab yeej xws li optical microscopes, electron microscopes, thiab atomic force microscopes (AFMs). Vim tias kev ua tau zoo ntawm cov cuab yeej ntsuas no nyob ntawm lawv qhov ruaj khov, qhov tseeb, thiab kev tiv thaiv kev co, granite yog qhov kev xaiv zoo tshaj plaws rau lawv cov khoom siv txaj. Qhov sib xws thiab kev ruaj khov ntawm granite txaj muab lub platform ruaj khov rau cov cuab yeej, uas ua rau lawv qhov tseeb thiab kev ntseeg siab.

Cov khoom siv lithography siv los ua cov qauv microchip ntawm lub wafer. Cov txheej txheem lithography xav tau qib siab ntawm kev raug thiab qhov tseeb los tsim cov voj voog nyuaj thiab txhim kho kev ua haujlwm ntawm lub chip. Cov khoom siv lithography suav nrog cov txheej txheem stepper thiab scanner uas siv lub teeb los hloov cov duab mus rau ntawm lub wafer. Raws li cov txheej txheem lithography muaj kev nkag siab zoo rau kev co thiab kev hloov pauv thermal, lub txaj zoo yog qhov tseem ceeb kom ntseeg tau tias muaj kev ruaj khov thiab rov ua dua ntawm cov txheej txheem lithography. Cov txaj granite muab qhov kev ruaj khov xav tau thiab kev ua haujlwm hnyav rau cov txheej txheem lithography. Lub txaj granite tso cai rau lub kaw lus stepper lossis scanner kom tswj tau qhov sib raug zoo ntawm qhov chaw kom ntseeg tau tias muaj qhov tseeb siab thiab qhov zoo ntawm cov khoom kawg.

Cov khoom siv tshuaj xyuas yog siv los nrhiav cov qhov tsis zoo hauv cov khoom siv semiconductor. Cov khoom siv tshuaj xyuas suav nrog cov tshuab xws li laser scanning microscopes, electron microscopes, thiab optical microscopes. Vim tias qhov xav tau cov khoom siv no kom raug, ruaj khov thiab tiv taus kev co, cov txaj granite yog cov khoom zoo meej. Granite cov khoom siv kho tshuab thiab qhov ntev ruaj khov pab hauv kev cais kev co, uas ua rau qhov tseeb ntawm cov zis ntawm cov khoom siv tshuaj xyuas zoo dua.

Xaus lus, lub txaj granite yog qhov tseem ceeb rau kev lag luam semiconductor thiab siv dav hauv ntau hom khoom siv. Nws cov yam ntxwv tshwj xeeb xws li kev ruaj khov ntawm qhov ntev, cov coefficient nthuav dav thermal qis, thiab kev ruaj khov zoo heev ua rau granite yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv txaj ntawm cov khoom siv semiconductor. Raws li lub txaj granite zoo muab kev ruaj khov, kev ua haujlwm raug, thiab kev tiv thaiv kev co rau cov khoom siv semiconductor, nws thaum kawg txhim kho qhov zoo ntawm cov khoom kawg. Yog li ntawd, kev siv lub txaj granite hauv cov khoom siv semiconductor yeej yuav txuas ntxiv mus rau ntau xyoo tom ntej.
