Kutsegula Kusintha kwa Semiconductor Silicon: Mphamvu ya China mu High-Purity 6N Crystal Boron Dopants
Pachimake pakupanga zinthu molondola, kukwera kulikonse kwa silicon ya semiconductor kumayamba ndi kulamulira kolondola pamlingo wa atomiki. Chinsinsi chokwaniritsa kulamulira kumeneku chili mu ma crystalline boron dopants oyera kwambiri. Monga chinthu chofunikira kwambiri pamakampani opanga zamagetsi apamwamba padziko lonse lapansi, 6N crystalline boron (yoyera ≥99.9999%), yokhala ndi mawonekedwe osasinthika, yakhala "womanga nyumba wosawoneka" wopanga ma chips ndi zida zamagetsi zamakono.
Chifukwa chiyani 6N ndi crystallineboron"Njira yopezera moyo" ya silicon ya semiconductor?
"Switch" Yolondola ya P-type: Pamene maatomu a boron a 6N alowetsedwa bwino mu semiconductor silicon lattice, amapanga "mabowo" ofunikira omwe amapatsa silicon wafer mphamvu yake ya P-type. Iyi ndiye maziko opangira ma diode, ma transistors a field-effect (FETs), komanso ma circuits ovuta.
Mwala wa maziko a magwiridwe antchito: Kuchita bwino, kukhazikika, ndi liwiro losinthira la zida za semiconductor zimadalira kwambiri kufanana ndi kuyera kwa doping. Zonyansa zilizonse (monga kaboni, mpweya, ndi zinthu zachitsulo) zimatha kugwira ntchito ngati mipanda yonyamulira, zomwe zimapangitsa kuti mphamvu yotuluka ichuluke komanso kulephera kwa chipangizocho. 6N boron crystalline imawongolera kuchuluka kwa zonyansa mpaka mulingo wa magawo pa biliyoni imodzi (ppb), kuonetsetsa kuti magwiridwe antchito amagetsi a semiconductor silicon ndi oyera komanso odalirika.
Choteteza njira zotenthetsera kwambiri: Ndi kutentha kopitirira 2300°C, crystalline boron imakhala ndi kutentha kokhazikika kwambiri. Pa nthawi yovuta monga kukula kwa silicon single crystal (njira ya Czochralski) kapena kufalikira kwa kutentha kwakukulu/kulowetsedwa kwa ion, 6N crystalline boron imasunga kukhazikika kwa kapangidwe kake popanda kuyambitsa zinthu zosayembekezereka kapena kuwonongeka, kuonetsetsa kuti njirayo ingathe kuyendetsedwa bwino komanso kubwerezabwereza.
Yatsimikiziridwa mu mapulogalamu apamwamba padziko lonse lapansi: Chisankho chodalirika kwa makasitomala aku Korea ndi Japan
Case 1 (Wopanga ma wafer a silicon wafer a ku South Korea): UrbanMines ' 6N boron powder (99.9999% kuyera, kukula kwa tinthu ta 2-3mm) idagwiritsidwa ntchito ngati key dopant mu uvuni wa Czochralski single crystal kuti ikule ma ingot apamwamba a silicon a semiconductor a P okhala ndi resistivity range yapadera popanga ma logic chips apamwamba.
Mlandu 2 (wopanga chipangizo cha silicon epitaxial/chida cha ku Japan): UrbanMines idasankhidwa kugula 6N pure boron dopant (purity 99.9999%, kukula kwa tinthu tating'onoting'ono -4+40 mesh). Dopant iyi imagwiritsidwa ntchito mu njira zokulira kapena kutentha kwambiri kuti ilamulire bwino kufalikira kwa boron mu semiconductor silicon epitaxial layer kapena junction region, kukwaniritsa zofunikira zolimba za zida zamagetsi zamagetsi (monga ma IGBT).
Kupereka kwa China: Ubwino Wabwino wa 6N Crystalline Boron
Poyang'anizana ndi kufunikira kwakukulu komwe kukukula kuchokera kumadera akuluakulu padziko lonse lapansi monga South Korea, Japan, ndi United States, kampani yathu yakhazikitsa zabwino zazikulu pakupanga ndi kupereka zinthu za boron zoyera kwambiri:
1. Kupita patsogolo kwa ukadaulo ndi chuma cha kukula kwake: Kudzera mu kafukufuku wopitilira ndi chitukuko, kampani yathu yadziwa bwino njira yayikulu yopangira β-rhombohedral boron yoyera kwambiri (yomwe ndi yokhazikika kwambiri). Izi zimatithandiza kupereka mitundu yonse ya kuyera, kuyambira 99% mpaka 6N (99.9999%) komanso yokwera kwambiri. Mphamvu yathu yokhazikika yopangira imatithandiza kukwaniritsa maoda akuluakulu ochokera kwa makasitomala akuluakulu padziko lonse lapansi (monga momwe tawonetsera pakufunikira kwathu pamwezi kwa 50kg ya amorphous boron yogwiritsidwa ntchito padzuwa).
2. Dongosolo lowongolera khalidwe molimbika: Potsatira miyezo yapadziko lonse lapansi ya semiconductor-grade, takhazikitsa njira yoyendetsera ndi kulamulira yoyera kwambiri pa ntchito yonseyi, yomwe ikuphatikizapo kufufuza zinthu zopangira, kupanga ma reaction, kuyeretsa ndi kuyeretsa (monga kusungunuka m'madera osiyanasiyana ndi kusungunuka kwa vacuum), kuphwanya ndi kuyika muyeso, ndi kulongedza. Izi zimatsimikizira kuti gulu lililonse la makristasi a 6N boron lili ndi kusinthasintha kwabwino kwambiri.
3. Kutha Kusintha Zinthu Mozama: Kampani yathu imamvetsetsa bwino zofunikira zenizeni za njira za semiconductor za boron (granules, powders) ndi kukula kwa tinthu (monga D50 ≤ 10μm, -200 mesh, 1-10mm, 2-4μm, etc.). Monga tafotokozera m'chikalatacho, "kupanga zinthu mwamakonda n'kotheka ngati zofunikira zinazake za tinthu zikukwaniritsidwa." Kuyankha kosinthasintha kumeneku ndikofunikira kwambiri kuti tipeze makasitomala apamwamba ku South Korea, Japan, ndi mayiko ena.
4. Mgwirizano wa Mabizinesi ndi Ubwino wa Mtengo: Pogwiritsa ntchito makina athunthu a mafakitale am'nyumba ndi zinthu zopangira, 6N crystalline boron yathu sikuti imangotsimikizira kuti ndi yapamwamba kwambiri komanso imadzitamandira ndi kulimba kwapamwamba kwa maukonde ogulitsa komanso mpikisano wathunthu wamitengo, kupereka chithandizo chokhazikika, chodalirika, komanso chotsika mtengo cha zinthu zofunika kwambiri pamakampani opanga ma semiconductor padziko lonse lapansi.
Pomaliza: Zipangizo za boron ku China zikutsogolera pakulimbikitsa ma chips amtsogolo
Kuyambira pa ma processor akuluakulu a mafoni a m'manja mpaka ma chip amphamvu omwe amalimbitsa "ubongo" wa magalimoto atsopano amphamvu, malire a magwiridwe antchito a silicon ya semiconductor akupitilizabe kufotokozedwa ndi kuyera ndi kulondola kwa ma crystalline boron dopants a 6N. Makampani opanga boron oyeretsa kwambiri ku China, omwe ali ndi ukadaulo wolimba, kuwongolera bwino khalidwe, kuthekera kosintha zinthu, komanso mphamvu yolimba yopanga, akukhala chinthu chofunikira kwambiri pakupanga zinthu zatsopano padziko lonse lapansi.
Kusankha kampani yodalirika yogulitsa makristalo a 6N boron ku China kumatanthauza kusankha njira yomveka bwino yopita ku tsogolo la silicon ya semiconductor. Popeza tili ndi chidwi kwambiri ndi boron yoyera kwambiri, tili ndi luso lopanga komanso mayankho okonzedwa kuti tikwaniritse ntchito zofunika kwambiri za semiconductor. Lumikizanani nafe lero kuti mulowetse mphamvu yamphamvu komanso yolondola ya boron yaku China muzipangizo zanu zamakono za silicon ya semiconductor!
