Kev lag luam semiconductor muaj qhov yuav tsum tau nruj tshaj plaws rau graphite purity ntawm txhua qhov kev lag luam. Thaum lub sij hawm wafer thermal ua, tej impurity nag lossis daus yuav ua rau wafer paug, uas ua rau cov chips loj heev. Rau cov txheej txheem semiconductor siab heev, graphite tshauv cov ntsiab lus feem ntau yuav tsum tau qis dua 5ppm. Fine-grain isostatic graphite yog thawj cov khoom siv raw, ua tsaug rau cov qauv microstructure, tsis tshua muaj particle shedding thiab machinability zoo heev.
Graphite cov khoom siv dav siv hauv cov khoom siv semiconductor suav nrog graphite susceptors, graphite heaters, thermal shielding cylinders, wafer nqa graphite fixtures, graphite qhia raj thiab graphite sealing rings. Cov xwm txheej ua haujlwm txawv heev raws li hom khoom siv. Nyob rau hauv monocrystalline silicon rub furnaces, graphite Cheebtsam ntsib kev yaig ntawm silicon vapor; Hauv SiC PVT kev loj hlob rauv, graphite yuav tsum tau tiv taus ultra- kub siab tshaj 2200℃; nyob rau hauv epitaxy thiab diffusion furnaces, graphite Cheebtsam hu rau corrosive txheej txheem roj rau lub sij hawm ntev.
Cov txheej txheej saum npoo tau dhau los ua qauv txheej txheem rau ntau cov khoom siv semiconductor graphite. Pyrolytic carbon coating and SiC coating form a dense protective layer on graphite surface, blocking graphite particle shedding and preventing reaction between graphite and process gas, greatly extending component service life. Nyob rau tib lub sijhawm, txheej kev kho mob nce siab dua ntawm graphite substrate machining precision, nto roughness thiab qhov ntev ntev.
Loj -loj wafer txoj kev loj hlob txoj kev thawb graphite tivthaiv loj hloov kho. Raws li 300mm wafers dhau los ua qhov tseem ceeb thiab 450mm wafer thev naus laus zis tsim, monolithic loj graphite kub cheeb tsam tau txais kev pom zoo los txo qhov sib dhos thiab txhim kho qhov kub thiab txias. Kev tsim khoom loj- qhov loj me tsis muaj qhov tsis zoo isostatic graphite blanks thiab paub txog qhov tseeb machining yog cov kev sib tw loj rau cov tuam txhab graphite.
Huixian Jincheng Abrasive & Graphite Pwm Hoobkas muab precision machining kev pab cuam rau semiconductor - qib graphite Cheebtsam. Founded hauv 1984, lub lag luam txheej txheem tiav graphite qhov chaw raws li imported siab -purity isostatic graphite blanks. Nruab nrog siab -CNC graphite ua cov cuab yeej, Jincheng Graphite paub siab -precision machining ntawm complex graphite fixtures, tshav kub shields thiab txhawb cov khoom rau semiconductor thermal khoom. Lub Hoobkas tuaj yeem koom tes nrog cov neeg siv khoom kom ua tiav ua ntej- kev kho mob xws li ntxuav thiab polishing ua ntej txheej. Kev ntsuas kev sib koom ua ke nruj thiab kev soj ntsuam zoo li yog siv rau txhua pawg ntawm cov khoom kom lav qhov ruaj khov ntawm qhov ntev. Txawm hais tias Jincheng Graphite feem ntau tsom rau kev ua haujlwm ntawm cov khoom siv graphite, nws tswj kev sib txuas lus nrog cov neeg muab txheej txheem kom xa cov khoom tiav tiav rau cov khoom siv semiconductor.
Ntiaj teb no semiconductor muaj peev xwm nthuav mus txuas ntxiv ntawm kev thov rau siab -kev ua tau zoo graphite consumables. Localization ntawm cov khoom siv semiconductor coj kev lag luam loj loj rau kev lag luam graphite ua lag luam. Jincheng Graphite yuav txuas ntxiv txhim kho precision machining muaj peev xwm thiab kev tswj kom zoo, los txhawb cov khoom siv saw hlau ntawm semiconductor thermal khoom graphite qhov chaw.
