Kev Txhim Kho Tshiab hauv Zone Melting Technology

1. Kev Tshawb Fawb Tshiab hauv Kev Npaj Khoom Siv Uas Muaj Kev Ntshiab Siab
Cov Khoom Siv Uas Siv Silicon: Qhov huv ntawm cov siv lead ua los ntawm silicon tau dhau ‌13N (99.99999999999%) siv txoj kev floating zone (FZ), ua rau kev ua haujlwm ntawm cov khoom siv semiconductor muaj zog heev (piv txwv li, IGBTs) thiab cov chips siab heev‌45. Cov thev naus laus zis no txo ​​cov pa oxygen los ntawm cov txheej txheem tsis muaj crucible thiab koom ua ke silane CVD thiab hloov kho Siemens txoj kev kom ua tiav kev tsim khoom zoo ntawm thaj chaw-melting-qib polysilicon‌47.
Cov Khoom Siv Germanium: Kev ua kom huv ntawm thaj chaw yaj zoo tshaj plaws tau ua kom germanium purity nce mus txog 13N, nrog rau cov coefficients faib tawm impurity zoo dua, ua rau muaj kev siv rau hauv infrared optics thiab cov khoom siv hluav taws xob 23. Txawm li cas los xij, kev sib cuam tshuam ntawm germanium yaj thiab cov khoom siv khoom siv ntawm qhov kub siab tseem yog qhov nyuaj heev 23.
2. Kev Tsim Kho Tshiab hauv Cov Txheej Txheem thiab Cov Khoom Siv
Kev Tswj Xyuas Dynamic Parameter: Kev kho kom haum rau qhov ceev ntawm thaj chaw yaj, qhov kub thiab txias, thiab cov pa roj tiv thaiv - ua ke nrog kev saib xyuas lub sijhawm tiag tiag thiab cov txheej txheem tawm tswv yim tsis siv neeg - tau txhim kho cov txheej txheem ruaj khov thiab rov ua dua thaum txo qis kev sib cuam tshuam ntawm germanium / silicon thiab cov khoom siv 27.
Kev Tsim Polysilicon: Cov txheej txheem tshiab uas tuaj yeem nthuav dav rau thaj chaw-melting-qib polysilicon daws cov teeb meem tswj cov pa oxygen hauv cov txheej txheem ib txwm muaj, txo kev siv hluav taws xob thiab txhawb nqa cov txiaj ntsig 47.
3. Kev Sib Koom Tes Hauv Technology Thiab Kev Siv Ntau Yam Kev Kawm
Kev Sib Xyaws Ua Ke ntawm Cov Khoom Siv Crystallization: Cov txheej txheem ua kom cov khoom siv crystallization uas siv zog tsawg tau raug koom ua ke los ua kom zoo dua qhov kev sib cais thiab kev ntxuav cov organic compound, nthuav dav cov ntawv thov melting hauv cov tshuaj intermediates thiab cov tshuaj zoo.
Cov Khoom Siv Semiconductors Thib Peb: Kev yaj thaj tsam tam sim no siv rau cov ntaub ntawv dav dav xws li silicon carbide (SiC) thiab gallium nitride (GaN), txhawb nqa cov khoom siv zaus siab thiab kub siab. Piv txwv li, cov thev naus laus zis ua kom muaj kev loj hlob ntawm SiC siv lead ua kom ruaj khov los ntawm kev tswj qhov kub thiab txias meej15.
4. Cov Xwm Txheej Thov Sib Txawv
‌Photovoltaics‌: Cov polysilicon uas yaj hauv cheeb tsam yog siv rau hauv cov roj teeb hnub ci ua haujlwm tau zoo, ua tiav cov txiaj ntsig hloov pauv photoelectric ntau dua 26% thiab tsav kev nce qib hauv lub zog rov ua dua tshiab‌4.
Cov Txuj Ci Infrared thiab Detector: Ultra-high-purity germanium ua rau muaj cov duab infrared me me, ua haujlwm siab thiab cov khoom siv pom kev hmo ntuj rau tub rog, kev ruaj ntseg, thiab kev lag luam pej xeem23.
5. Cov Kev Cov Nyom thiab Cov Lus Qhia Yav Tom Ntej
Kev Txwv Kev Tshem Tawm Tsis Huv: Cov txheej txheem tam sim no muaj teeb meem nrog kev tshem tawm cov khoom tsis huv ntawm lub teeb (piv txwv li, boron, phosphorus), xav tau cov txheej txheem doping tshiab lossis cov thev naus laus zis tswj thaj chaw yaj dynamic25.
Kev Siv Khoom Siv Ruaj Khov thiab Kev Siv Hluav Taws Xob Zoo: Kev tshawb fawb tsom mus rau kev tsim cov khoom siv crucible uas tiv taus kub thiab tiv taus xeb thiab cov tshuab cua sov radiofrequency kom txo kev siv hluav taws xob thiab txuas lub neej ntawm cov khoom siv. Kev siv tshuab Vacuum arc remelting (VAR) qhia txog kev cog lus rau kev ua kom zoo hlau47.
Cov thev naus laus zis zone melting tab tom nce qib mus rau qhov purity siab dua, tus nqi qis dua, thiab kev siv tau dav dua, ua kom nws lub luag haujlwm ua lub hauv paus tseem ceeb hauv semiconductors, lub zog rov ua dua tshiab, thiab optoelectronics.
