Zatsopano Zatsopano mu Zone Melting Technology

1. Kupititsa patsogolo Kukonzekera Kwachinthu Choyera Kwambiri
Zida Zopangira Silicon: Kuyera kwa makristalo a silicon amodzi kwaposa 13N (99.9999999999%) pogwiritsa ntchito njira yoyandama (FZ), kupititsa patsogolo magwiridwe antchito a zida zamphamvu za semiconductor (mwachitsanzo, IGBTs) ndi tchipisi totsogola45. Ukadaulowu umachepetsa kuipitsidwa kwa okosijeni kudzera munjira yopanda crucible ndikuphatikiza silane CVD ndi kusinthidwa kwa njira za Nokia kuti akwaniritse kupanga bwino kwa zone-melting-grade polysilicon 47.
Zida za Germanium : Kuyeretsedwa kwa zone kusungunuka kwakweza germanium chiyero kufika ku 13N, ndi makina ogawa zonyansa, zomwe zimathandiza kuti ntchito za infrared optics ndi ma radiation detectors23. Komabe, kuyanjana pakati pa germanium yosungunuka ndi zida za zida pa kutentha kwakukulu kumakhalabe vuto lalikulu 23.
2. Zatsopano mu Njira ndi Zida
Dynamic Parameter Control: Kusintha kwa kusungunula kuthamanga kwa madera, kutentha kwa kutentha, ndi malo otetezera mpweya-kuphatikizana ndi kuyang'anira nthawi yeniyeni ndi machitidwe owonetsera okhawokha - kwathandizira kukhazikika kwa ndondomeko ndi kubwerezabwereza pamene kuchepetsa kuyanjana pakati pa germanium / silicon ndi zipangizo 27.
Kupanga kwa Polysilicon: Njira zatsopano zosinthira polysilicon yosungunuka m'malo amalimbana ndi zovuta zowongolera mpweya m'njira zachikhalidwe, kuchepetsa kugwiritsa ntchito mphamvu komanso kukulitsa zokolola47.
3. Kuphatikizika kwa Tekinoloje ndi Ntchito Zosiyanasiyana
Sungunulani Crystallization Hybridization: Njira zochepetsera mphamvu zosungunula kristalo zikuphatikizidwa kuti zikwanitse kulekanitsa ndi kuyeretsa, kukulitsa ntchito zosungunula zone m'malo opangira mankhwala ndi mankhwala abwino6.
Ma Semiconductors a M'badwo Wachitatu: Kusungunuka kwa malo tsopano kukugwiritsidwa ntchito ku zipangizo zamtundu wambiri monga silicon carbide (SiC) ndi gallium nitride (GaN), zothandizira zipangizo zothamanga kwambiri komanso kutentha kwambiri. Mwachitsanzo, ukadaulo wa ng'anjo yamadzi-gawo limodzi wa kristalo umathandizira kukula kokhazikika kwa makristalo a SiC kudzera pakuwongolera kutentha kwanthawi zonse 15.
4. Mitundu Yosiyanasiyana Yogwiritsa Ntchito
Photovoltaics: Zone-melting-grade polysilicon imagwiritsidwa ntchito m'maselo a solar amphamvu kwambiri, kukwanitsa kutembenuza ma photoelectric kupitilira 26% ndikuyendetsa kupita patsogolo kwa mphamvu zongowonjezwdwa4.
Ma Infrared and Detector Technologies: Ultra-high-purity germanium imathandizira kuyerekezera kwapang'onopang'ono, kowoneka bwino kwambiri komanso zida zowonera usiku zankhondo, chitetezo, ndi misika ya anthu wamba23.
5. Mavuto ndi Njira Zamtsogolo
Malire Ochotsa Chidetso: Njira zomwe zilipo pano zimalimbana ndi kuchotsa zonyansa zamtundu wa kuwala (mwachitsanzo, boron, phosphorous), kufunikira kwa njira zatsopano za doping kapena matekinoloje amphamvu owongolera malo osungunuka 25.
Kukhalitsa kwa Zida ndi Mphamvu Zamagetsi: Kafukufuku amayang'ana kwambiri pakupanga zida zosagwirizana ndi kutentha kwambiri, zosagwira corrosion ndi makina otenthetsera ma radiofrequency kuti achepetse kugwiritsa ntchito mphamvu ndikuwonjezera moyo wa zida. Tekinoloje ya Vacuum arc remelting (VAR) ikuwonetsa lonjezano pakuwongolera zitsulo47.
Ukadaulo wosungunuka wa Zone ukupita patsogolo ku chiyero chokwera, kutsika mtengo, komanso kugwiritsa ntchito mokulirapo, kulimbitsa udindo wake monga mwala wapangodya wama semiconductors, mphamvu zongowonjezwdwa, ndi ma optoelectronics.
