Daim ntawv thov ntawm Translucent Alumina Ceramics hauv Semiconductors
Translucent alumina ceramics yog hom siab -purity alumina ceramics. Vim lawv cov kev hloov kho qhov muag, lawv tuaj yeem siv los ua cov khoom siv ceramic ua ke nrog ob qho tib si kev ua haujlwm thiab cov yam ntxwv. Cov yam ntxwv ntawm cov densification siab thiab tsawg qhov pores thiab impurity tsis xws luag txhais tau hais tias translucent alumina ceramics feem ntau muaj cov khoom zoo tshaj plaws ntau dua li qhov siab tshaj -purity alumina ceramics. Piv rau sapphire ib leeg siv lead ua, translucent alumina ceramics tuav qhov zoo ntawm cov khoom siv kho tshuab thiab suav tias yog ib qho ntawm cov khoom siv ceramic nyiam rau kev sib koom ua ke thiab kev ua haujlwm.
Kev siv hauv cov khoom siv semiconductor
Hauv kev tsim khoom semiconductor, cov txheej txheem etching yog ib kauj ruam tseem ceeb. Tshwj xeeb, kev xaiv ntawm cov ntaub ntawv rau etch chamber viewports yuav tsum tsis tsuas yog high transmittance tab sis kuj zoo heev corrosion kuj. Thaum xub thawj, quartz feem ntau siv. Txawm li cas los xij, quartz qhov tsis muaj zog corrosion ua rau nws yooj yim rau kev puas tsuaj thiab clouding, txo nws cov kev pab cuam lub neej raws li ib tug viewport. Translucent alumina ceramics tau txais kev saib xyuas vim lawv qhov zoo tshaj plaws optical transmittance, zoo heev tshuaj tsis kam, thiab dielectric zog.
Alumina ceramic viewports nthuav tawm lub neej ua haujlwm ntev heev. High optical transmittance yog lawv qhov tseem ceeb kom zoo dua rau daim ntawv thov no, siab purity ua kom tsis muaj zog plasma etching, thiab siab densification txo dielectric poob, txo cov hluav taws kub thaum lub sij hawm siv khoom. Txawm hais tias translucent alumina ceramics ua tau zoo hauv plasma etching tsis kam, lawv cov khoom siv kho qhov muag tseem tseem poob qab cov ntaub ntawv zoo li quartz. Tshwj xeeb tshaj yog nyob rau hauv fluorine- muaj cov plasma etching ib puag ncig, Al reacts nrog F los ua AlxFy tebchaw, uas tsis tsuas yog shortens lub neej ntawm translucent alumina ceramic tab sis kuj ua rau muaj kev pheej hmoo ntawm wafer paug.
Daim ntawv thov hauv Semiconductor Ntim
Hauv cov txheej txheem ntim khoom semiconductor, txhawm rau ua kom zoo dua qhov kev hloov pauv ntawm cov duab hluav taws xob ntawm LED chips, cov qauv nruj dua yog tsim los ntawm cov khoom siv kho qhov muag thiab thermal ntawm cov khoom ntim. Translucent alumina ceramics, raws li cov ntaub ntawv ntim, tsis yog tsuas yog ua haujlwm ob lub luag haujlwm raws li kev txhawb nqa substrates thiab tshav kub dissipation txoj hauv kev tab sis kuj, leveraging lawv cov khoom kho qhov muag tshwj xeeb, muaj txiaj ntsig zoo kov yeej qhov teeb meem ntawm kev txwv luminous efficiency tshwm sim los ntawm unidirectional lub teeb paths. Tshwj xeeb tshaj yog, siv lawv cov kev xa tawm siab, lawv tau ua haujlwm ua pob tshab substrates thiab pob tshab raj, tso cai rau lub teeb tsim los ntawm LED chips kom nthuav tawm ib yam nkaus thiab tsis muaj kev cuam tshuam rau txhua qhov kev qhia, yog li ua kom muaj txiaj ntsig zoo ntawm tag nrho cov teeb pom kev zoo ntawm LED teeb pom kev zoo. Tsis tas li ntawd, translucent alumina ceramics muaj chav zoo heev -kub thermal conductivity, zoo txo cov thermal zog generated thaum lub sij hawm LED nti ua hauj lwm, ntxiv txhim kho tag nrho cov kev ua tau zoo thiab stability.
Daim ntawv thov ntawm Translucent Alumina Ceramics hauv LED Teeb pom kev zoo
Thaum lub Plaub Hlis 2026, Nyiv Fine Ceramics Co., Ltd. (JFC) tshaj tawm tias nws tau tsim cov qauv translucent alumina substrate (kwv yees li 300 mm²), ib yam khoom uas xav tias yuav pom kev loj hlob tsis tu ncua hauv kev ntim khoom siab hauv cov txheej txheem tsim khoom semiconductor.
Qhov no translucent alumina substrate yog tsim los ntawm siab -purity alumina (tshaj 99.99%) thiab tau lees paub tias muaj peb yam ntxwv:
High optical transmittance hla lub ultraviolet (UV) rau infrared (IR) wavelength ntau yam.
High rigidity sib npaug ntawm sapphire.
Cov tshuaj tiv thaiv zoo heev.
JFC tau qhia tias cov translucent alumina substrate zoo li yuav siv tau rau hauv IGBT modules rau siab - lub zog semiconductor ntim, LED teeb pom kev zoo, siab- kev sib txuas lus zaus (5G/mmWave), thiab tshwj xeeb tshaj yog muaj peev xwm tshiab rau kev sib txuas lus kho qhov muag xws li Co-Packaged Optics rau kev siv tshuaj lom neeg thiab kev ruaj ntseg (CPO).
Nrog rau kev loj hlob sai ntawm AI generative, qhov kev thov rau siab -kev ua tau zoo semiconductors tau loj hlob tas li. Pob tshab alumina wafers yog ib hom kev txhawb nqa wafer siv rau kev kho ib ntus semiconductor chips thaum lub sij hawm chiplet kev koom ua ke.
NGK Insulators, Ltd. npaj yuav triple nws lub peev xwm ntau lawm rau pob tshab alumina wafers los ntawm kev siv nyiaj xyoo 2027 kom tau raws li qhov kev thov loj hlob rau kev sib koom ua ke chiplet -ib qho thev naus laus zis tseem ceeb hauv kev ua haujlwm siab xws li Artificial Intelligence (AI) thiab kev tsav tsheb tsis muaj zog. Los ntawm qhov kev nthuav dav no, NGK Group lub hom phiaj los tsim kom muaj cov khoom siv ruaj khov thiab sib zog ua kom tau txais kev muag khoom ntawm 20 billion yen nyob rau hauv siab -kev ua lag luam semiconductor los ntawm kev siv nyiaj xyoo 2030.
Lub pob tshab alumina wafer siv "HICERAM," cov khoom siv zoo nkauj ceramic tsim thiab ua kom zoo los ntawm NGK ntau xyoo. "HICERAM" yog translucent precision ceramic khoom raws li siab -purity alumina (Al₂O₃). Los ntawm kev tswj hwm ntawm cov khoom siv raw purity, qhov loj me, thiab cov txheej txheem sintering, cov khoom no ua tiav zoo translucency hauv polycrystalline alumina thaum tswj kev ceev. Piv nrog rau cov tsoos ceramics, nws ua kom pom qhov ua tau zoo hauv kev txo qhov pores thiab lub teeb tawg, yog li ua kom muaj qee qhov kev sib kis ntawm lub teeb thaum tswj kev ua haujlwm ntawm lub zog.
Txhawm rau npaj siab -kev ua tau zoo translucent alumina ceramics, siab -purity alumina hmoov nrog ib tug purity tsis tsawg tshaj li 99.99% yog yuav tsum tau. Cov ntsiab lus impurity (xws li silicon thiab hlau) tuaj yeem tsim cov chaw tawg pleb ntawm cov ciam teb, txo qis kev xa tawm thiab cuam tshuam rau cov khoom siv microstructure; Yog li, tswj cov ntsiab lus impurity hauv cov hmoov (qhov qis dua, qhov zoo dua) yog qhov tseem ceeb heev. Lwm qhov teeb meem tseem ceeb yog dispersibility ntawm hmoov hais. Yog hais tias particle agglomeration hnyav heev, txawm tias siv 99.99% purity raw cov ntaub ntawv yuav tsis tawm los tsim nyog translucent ceramics. Tsis tas li ntawd, cov kev cai nruj yog muab tso rau ntawm kev ua haujlwm sintering ntawm alumina hmoov.
