1. Kev ua txhaum ntawm High-Purity Material Preparation
Silicon-based Materials : Lub purity ntawm silicon ib leeg muaju tau tshaj 13N (99.9999999999%) siv qhov chaw ntab (FZ) txoj kev, txhawb kev ua tau zoo ntawm cov khoom siv hluav taws xob muaj zog (xws li IGBTs) thiab cov chips siab heev 45. Cov thev naus laus zis no txo cov pa paug los ntawm cov txheej txheem crucible-free thiab integrates silane CVD thiab hloov Siemens txoj kev kom ua tiav cov khoom tsim tau zoo ntawm cheeb tsam-melting-qib polysilicon 47.
Cov khoom siv hauv German: Optimized zone melting purification tau nce germanium purity mus rau 13N, nrog kev txhim kho impurity faib coefficients, ua kom muaj kev siv hauv infrared optics thiab hluav taws xob ntes 23. Txawm li cas los xij, kev sib cuam tshuam ntawm molten germanium thiab cov khoom siv ntawm qhov kub thiab txias tseem yog qhov nyuaj heev 23.
2. Kev tsim kho tshiab hauv cov txheej txheem thiab cov khoom siv
Dynamic Parameter Control : Kev hloov kho kom nrawm nrawm nrawm, qhov kub thiab txias, thiab kev tiv thaiv roj ib puag ncig-coupled nrog lub sijhawm saib xyuas thiab cov lus qhia tsis siv neeg-tau txhim kho cov txheej txheem kev ruaj ntseg thiab rov ua dua thaum txo kev sib cuam tshuam ntawm germanium / silicon thiab cov khoom siv 27.
Polysilicon Production : Novel scalable method for zone-melting-grade polysilicon addresses oxygen content control challenges in traditional processes, txo hwj chim noj thiab boosting yield 47.
3. Kev sib koom ua ke thev naus laus zis thiab kev siv hla kev qhuab qhia
Melt Crystallization Hybridization : Cov txheej txheem qis-zog yaj crystallization tau muab tso ua ke los txhim kho cov organic compound sib cais thiab ua kom huv si, nthuav dav thaj tsam melting daim ntawv thov hauv cov tshuaj intermediates thiab tshuaj zoo 6.
Third-Generation Semiconductors : Zone melting yog tam sim no siv rau cov ntaub ntawv dav dav xws li silicon carbide (SiC) thiab gallium nitride (GaN), txhawb cov khoom siv high-frequency thiab high-temperature. Piv txwv li, kua-theem ib leeg-crystal rauv tshuab ua kom ruaj khov SiC siv lead ua kev loj hlob los ntawm kev tswj qhov kub thiab txias 15.
4. Diversified Application Scenarios
Photovoltaics : Zone-melting-qib polysilicon yog siv nyob rau hauv high-efficiency solar cells, ua tiav photoelectric conversion efficiency tshaj 26% thiab tsav tsheb mus rau hauv renewable zog 4.
Infrared thiab Ntes Technologies: Ultra-high-purity germanium enables miniaturized, high-performance infrared imaging thiab hmo ntuj-pob ntseg khoom siv rau tub rog, kev ruaj ntseg, thiab pej xeem kev lag luam 23.
5. Cov kev sib tw thiab cov kev taw qhia yav tom ntej
Impurity Tshem Tawm Cov Txwv: Cov txheej txheem tam sim no tawm tsam nrog tshem tawm cov teeb pom kev tsis huv (xws li boron, phosphorus), yuav tsum muaj cov txheej txheem tshiab doping lossis dynamic melt zone control technologies 25.
Cov cuab yeej siv tau ntev thiab lub zog ua kom muaj zog: Kev tshawb fawb tsom mus rau kev tsim cov khoom kub-tiv taus, corrosion-resistant crucible cov ntaub ntawv thiab cov xov tooj cua cua kub cua kom txo tau lub zog siv thiab ua kom cov cuab yeej siv tau ntev. Nqus arc remelting (VAR) thev naus laus zis qhia kev cog lus rau kev kho hlau 47.
Zone melting thev naus laus zis tau nce mus rau purity siab dua, tus nqi qis dua, thiab kev siv dav dua, ua kom nws lub luag haujlwm ua lub hauv paus tseem ceeb hauv cov khoom siv hluav taws xob, lub zog tauj dua tshiab, thiab optoelectronics.
