Quartz: Ib qho tseem ceeb hauv cov khoom siv hluav taws xob niaj hnub
Kev Taw Qhia Txog Cov Khoom Siv Quartz
Quartz (SiO₂) tej zaum yuav zoo li iav thaum xub thawj siab, tab sis nws cov yam ntxwv tshwj xeeb ua rau nws txawv. Tsis zoo li cov iav txheem, uas muaj ntau yam khoom (xws li xuab zeb quartz, borax, barium carbonate, limestone, feldspar, thiab soda), quartz tsuas yog tsim los ntawm SiO₂. Qhov no muab nws cov qauv yooj yim tsim los ntawm tetrahedral units ntawm silicon dioxide..
Qhov Tseem Ceeb ntawm High-Purity Quartz
Quartz uas muaj purity siab, feem ntau hu ua "lub pov haum zoo nkauj" ntawm cov khoom siv iav, muaj cov yam ntxwv zoo heev vim nws cov khoom tsis muaj hlau tsawg heev. Cov khoom siv zoo kawg no yog qhov tseem ceeb hauv ntau yam txheej txheem semiconductor, khav txog qhov zoo xws li:
1. Kev Kub Siab: Nrog rau qhov chaw mos ntawm kwv yees li 1730 ° C, quartz tuaj yeem tiv taus kev siv mus sij hawm ntev ntawm 1150 ° C thiab tswj cov tawg luv luv txog li 1450 ° C.
2. Kev Tiv Thaiv Kev Tshuaj Lom Zem: Cov quartz uas muaj purity siab qhia tau tias muaj kev cuam tshuam tsawg heev nrog feem ntau cov kua qaub (tshwj tsis yog hydrofluoric acid) thiab qhia tau tias muaj kev ruaj khov zoo dua tiv thaiv kev tawm tsam los ntawm tshuaj lom neeg, ua 30 npaug ntau dua li cov kua qaub dua li cov khoom siv ceramics thiab 150 npaug ntau dua li cov hlau tsis xeb.
3. Kev Ruaj Ntseg Thermal: Cov quartz uas muaj purity siab muaj cov coefficient thermal expansion qis heev, uas ua rau nws muaj peev xwm nyiaj tau qhov kub hloov pauv sai yam tsis muaj kev tawg.
4. Kev Pom Tseeb ntawm Lub Teeb: Cov khoom siv no tswj tau qhov kev xa tawm siab thoob plaws ntau qhov spectrum, nrog rau kev xa tawm lub teeb pom kev zoo tshaj 93% thiab kev xa tawm ultraviolet siab tshaj 80%.
5. Kev Rwb Thaiv Hluav Taws Xob: Cov quartz uas muaj purity siab muaj kev tiv thaiv hluav taws xob zoo heev, ua rau nws yog ib qho insulator zoo heev txawm tias nyob rau qhov kub siab.
Cov ntawv thov hauv kev lag luam semiconductor
Vim yog cov khoom siv lub cev thiab tshuaj lom neeg zoo kawg no, cov quartz uas muaj cov khoom huv si siab tau siv dav hauv cov khoom siv hluav taws xob niaj hnub, kev sib txuas lus, thiab kev lag luam semiconductor. Qhov kev thov rau silicon wafers uas loj hlob zuj zus tau ua rau muaj kev xav tau ntau ntxiv rau cov khoom siv quartz, tshwj xeeb tshaj yog hauv kev tsim cov chips.
Cov Ntawv Thov Tseem Ceeb ntawm Quartz hauv Semiconductor Manufacturing:
1. Cov Khoom Siv Kub Siab:
Cov raj cua sov Quartz:Tseem ceeb rau cov txheej txheem xws li diffusion, oxidation, thiab annealing, cov raj no ua kom muaj kev ruaj khov thiab ua haujlwm tau zoo thaum lub sijhawm tsim khoom semiconductor.
·Cov Nkoj Quartz:Siv rau kev thauj mus los thiab ua cov silicon wafers, cov nkoj quartz pab txhawb kev tsim khoom ntau hauv cov txheej txheem diffusion.
2. Cov Khoom Siv Kub Qis:
· Cov Nplhaib Quartz:Ib feem tseem ceeb ntawm cov txheej txheem etching, cov nplhaib quartz tiv thaiv kev ua qias tuaj thiab xyuas kom meej tias kev tsim khoom raug thaum lub sijhawm lithography thiab patterning.
Cov Pob Tawb Ntxuav thiab Cov Thawv Dej Quartz:Cov khoom no tseem ceeb heev rau kev ntxuav cov silicon wafers. Lawv yuav tsum tiv taus cov kua qaub thiab alkali thaum txo qhov chaw sib cuag kom txo tau qhov ua kom huv.
