Semiconductor Quartz: Ib qho tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no
Taw qhia rau cov khoom siv Quartz
Quartz (SiO₂) yuav zoo li iav thaum xub thawj siab ib muag, tab sis nws cov khoom tshwj xeeb muab nws sib nrug. Tsis zoo li cov iav txheej txheem, uas muaj ntau yam khoom (xws li quartz xuab zeb, borax, barium carbonate, limestone, feldspar, thiab dej qab zib), quartz yog tsim los ntawm SiO₂. Qhov no muab nws ib qho yooj yim network qauv tsim los ntawm tetrahedral units ntawm silicon dioxide.
Qhov tseem ceeb ntawm High-Purity Quartz
High-purity quartz, feem ntau hu ua "crown jewel" ntawm cov ntaub ntawv iav, muaj cov khoom tshwj xeeb vim nws cov hlau tsis huv. Cov khoom zoo kawg li no yog qhov tseem ceeb hauv ntau yam txheej txheem semiconductor, boasting zoo xws li:
1. Kev Tiv Thaiv Kub Kub: Nrog rau qhov muag muag ntawm kwv yees li 1730 ° C, quartz tuaj yeem tiv taus kev siv mus sij hawm ntev ntawm 1150 ° C thiab tuav cov tawg luv luv txog 1450 ° C.
2. Chemical Corrosion Resistance: High-purity quartz exhibits me me reactivity nrog feem ntau cov acids (tshwj tsis yog hydrofluoric acid) thiab qhia superior stability tiv thaiv tshuaj tua kab mob, ua 30 npaug ntau acid-resistant dua ceramics thiab 150 npaug ntau resistant dua stainless hlau.
3. Thermal Stability: High-purity quartz muaj qhov thermal expansion coefficient tsis tshua muaj siab, ua rau nws tiv taus qhov kub thiab txias hloov pauv yam tsis muaj qhov tawg.
4. Optical Clarity: Cov khoom no tswj cov kev xa tawm siab thoob plaws qhov dav, nrog pom lub teeb kis tau zoo tshaj 93% thiab ultraviolet transmittance mus txog 80%.
5. Hluav taws xob rwb thaiv tsev: High-purity quartz muaj tshwj xeeb hluav taws xob tiv thaiv, ua rau nws zoo heev insulator txawm nyob rau hauv siab kub.
Cov ntawv thov hauv Kev Lag Luam Semiconductor
Vim yog cov khoom zoo ntawm lub cev thiab tshuaj lom neeg, lub siab purity quartz yog siv dav hauv cov khoom siv hluav taws xob niaj hnub, kev sib txuas lus, thiab kev lag luam semiconductor. Qhov kev thov loj zuj zus rau silicon wafers tau nce qhov xav tau ntawm cov khoom siv quartz, tshwj xeeb hauv kev tsim cov chips.
Kev siv tseem ceeb ntawm Quartz hauv Semiconductor Manufacturing:
1. Cov Cuab Yeej Kub Kub:
· Quartz Rauv Tubes:Qhov tseem ceeb rau cov txheej txheem xws li diffusion, oxidation, thiab annealing, cov hlab no ua kom muaj qhov kub thiab txias thiab ua haujlwm tau zoo thaum lub sij hawm tsim khoom semiconductor.
· Quartz Boats:Siv rau kev thauj thiab ua silicon wafers, quartz nkoj pab txhawb batch manufacturing hauv diffusion txheej txheem.
2. Cov Khoom Siv Kub Kub:
· Quartz Rings:Ib qho tseem ceeb rau cov txheej txheem etching, quartz rings tiv thaiv kev sib kis thiab xyuas kom meej kev tsim khoom thaum lub sij hawm lithography thiab qauv.
· Quartz Cleaning Baskets thiab Tank:Cov khoom no yog qhov tseem ceeb rau kev ntxuav silicon wafers. Lawv yuav tsum tiv taus cov kua qaub thiab alkali thaum txo qhov chaw sib cuag los txhim kho kev ua haujlwm huv.
