Ukuvula iSemiconductor Silicon Revolution: Amandla eTshayina kwiHigh-Purity 6N Crystal Boron Dopants
Kwincopho yokwenziwa ngokuchanekileyo, lonke ugqatso lokusebenza kwi-silicon ye-semiconductor luqala ngolawulo oluchanekileyo kwinqanaba le-athomu. Isitshixo sokufezekisa olu lawulo sikwii-boron ze-crystalline ezicocekileyo kakhulu. Njengezinto ezisisiseko eziyimfuneko kushishino lwe-elektroniki oluphambili lwehlabathi, i-6N crystalline boron (ubumsulwa ≥99.9999%), eneempawu zayo ezingenakutshintshwa, iye yaba "ngumyili wezakhiwo ongabonakaliyo" obumba iitships zanamhlanje kunye nezixhobo zamandla.
Kutheni i-6N i-crystallinei-boron"umgca wobomi" we-silicon ye-semiconductor?
“Iswitshi” yohlobo lwe-P echanekileyo: Xa iiathom ze-boron ze-6N zingeniswa ngokuchanekileyo kwi-semiconductor silicon lattice, zenza “imingxunya” ebalulekileyo enika i-silicon wafer yayo i-P-type conductivity. Esi sisiseko sokwakha ii-diode, ii-transistors ze-field-effect (ii-FET), kunye neesekethe ezidibeneyo ezintsonkothileyo.
Isiseko sokusebenza: Ukusebenza kakuhle, ukuzinza, kunye nesantya sokutshintsha kwezixhobo ze-semiconductor kuxhomekeke kakhulu ekufaneni nasekucocekeni kwe-doping. Nakuphi na ukungcola okuncinci (okufana nekhabhoni, ioksijini, kunye nezinto zesinyithi) kunokusebenza njengemigibe yokuthwala, okukhokelela ekwandeni kokuvuza komsinga kunye nokusilela kwesixhobo. I-6N boron crystalline ilawula amanqanaba okungcola ukuya kwinqanaba le-parts-per-billion (ppb), iqinisekisa ubunyulu obupheleleyo kunye nokuthembeka kokusebenza kombane we-semiconductor silicon.
Umlondolozi weenkqubo zobushushu obuphezulu: Njengoko iqondo lokunyibilika lingaphezulu kwama-2300°C, i-crystalline boron inozinzo olukhethekileyo lobushushu. Ngexesha leenkqubo ezifuna kakhulu ezifana nokukhula kwe-silicon single crystal (indlela yeCzochralski) okanye i-high-temperature diffusion/ion implantation annealing, i-6N crystalline boron igcina uzinzo lwesakhiwo ngaphandle kokungenisa ii-volatiles ezingalindelekanga okanye iimveliso zokubola, iqinisekisa ukuba inkqubo iyalawuleka kwaye iyaphindaphindeka.
Ingqinwe kwizicelo zehlabathi ezisemgangathweni: Ukhetho oluthembekileyo kubathengi baseKorea naseJapan
Ityala 1 (umenzi we-silicon wafer ye-semiconductor yaseMzantsi Korea): Umgubo we-boron we-UrbanMines '6N (ubumsulwa be-99.9999%, ubungakanani be-particle ye-2-3mm) wasetyenziswa njenge-dopant ephambili kwi-Czochralski single crystal furnace ukukhulisa ii-silicon ingots ze-semiconductor ze-P-type ezikumgangatho ophezulu ezinoluhlu oluthile lwe-resistivity yokwenza ii-logic chips eziphambili.
Ityala lesi-2 (umvelisi wesixhobo se-silicon epitaxial/isixhobo saseJapan): I-UrbanMines yamiselwa ukuthenga i-6N pure boron dopant (ubumsulwa yi-99.9999%, ubungakanani be-particle -4+40 mesh). Le dopant isetyenziswa kwiinkqubo zokukhula kwe-epitaxial okanye zokusasazwa kobushushu obuphezulu ukulawula ngokuchanekileyo ukusasazwa koxinzelelo lwe-boron kwi-semiconductor silicon epitaxial layer okanye ummandla we-junction, ukuhlangabezana neemfuno ezingqongqo zezixhobo zamandla aphezulu (ezifana nee-IGBTs).
Ubonelelo lwaseTshayina: Iingenelo zoBuchule ze-6N Crystalline Boron
Ijongene nemfuno ekhulayo ephezulu evela kwiindawo eziphambili ze-semiconductor zehlabathi ezifana neSouth Korea, iJapan, ne-United States, inkampani yethu iseke iingenelo ezibalulekileyo zemveliso kunye nokubonelela ngezixhobo ze-boron ezicocekileyo kakhulu:
1. Uphuhliso lwetekhnoloji kunye noqoqosho oluphezulu: Ngophando oluqhubekayo kunye nophuhliso, inkampani yethu ikwazile ukwenza imveliso enkulu ye-β-rhombohedral boron (eyona ndlela izinzileyo). Oku kusenza sikwazi ukubonelela ngoluhlu olupheleleyo lwamanqanaba okucoceka, ukusuka kwi-99% ukuya kwi-6N (99.9999%) nangaphezulu. Amandla ethu okuvelisa azinzileyo asivumela ukuba sihlangabezane nee-odolo ezinkulu ezivela kubathengi abakhulu behlabathi (njengoko kuboniswe yimfuno yethu yenyanga ye-50kg ye-boron engenasimo selanga).
2. Inkqubo yokulawula umgangatho ngokungqongqo: Sihambelana nemigangatho yamazwe ngamazwe ye-semiconductor-grade, simisele inkqubo yolawulo nolawulo olucocekileyo kakhulu kuyo yonke le nkqubo, equka ukuvavanywa kwezinto eziluhlaza, ukwenziwa kwe-reaction, ukucoca kunye nokucocwa (njengokunyibilika kwengingqi kunye ne-vacuum distillation), ukutyumza kunye nokubeka amanqaku, kunye nokupakishwa. Oku kuqinisekisa ukuba ibhetshi nganye yeekristale ze-6N boron inokuhambelana okuhle kakhulu.
