Furitaanka Kacaanka Silikoon ee Semiconductor: Xoogga Shiinaha ee Nadiifnimada Sare ee 6N Crystal Boron Dopants
Marka ugu sarreysa ee wax soo saarka saxda ah, waxqabad kasta oo ku dhaca silicon semiconductor-ka wuxuu ka bilaabmaa xakameyn sax ah oo heerka atomiga ah. Furaha lagu gaarayo xakamayntan waxay ku jirtaa burooyinka boron ee kristaliga ah ee aadka u saafiga badan. Iyada oo ah agab aasaasi ah oo aan lagama maarmaan u ah warshadaha elektaroonigga ee casriga ah, boron kristal 6N (daahirnimo ≥99.9999%), oo leh sifooyinkeeda aan la beddeli karin, ayaa noqotay "naqshadeeye aan la arki karin" oo qaabeeya jajabyada casriga ah iyo aaladaha korontada.
Waa maxay sababta crystalline 6N loo sameeyayboron"xariiqda nolosha" ee silikoon semiconductor-ka?
"Switch" nooca P-ga ah ee saxda ah: Marka atamka boron ee 6N si sax ah loogu soo bandhigo shabagga silikoonka semiconductor-ka, waxay abuuraan "godad" muhiim ah oo siiya wafer-ka silikoonka qaab-dhismeedka P-ga. Tani waa aasaaska dhismaha diode-yada, transistors-ka saamaynta goobta (FETs), iyo xitaa wareegyada isku dhafan ee isku dhafan.
Saldhigga waxqabadka: Hufnaanta, xasilloonida, iyo xawaaraha beddelka ee aaladaha semiconductor-ka waxay si weyn ugu xiran yihiin isku-midnimada iyo daahirnimada daawada. Wax kasta oo wasakh ah (sida kaarboon, oksijiin, iyo walxaha birta ah) waxay u dhaqmi karaan sidii dabino side, taasoo horseedaysa kororka qulqulka daadashada iyo cilladda qalabka. 6N boron crystalline wuxuu xakameeyaa heerarka wasakhda ilaa heerka qaybaha-bilyankiiba (ppb), isagoo hubinaya daahirnimada ugu dambeysa iyo isku halaynta waxqabadka korontada ee semiconductor silicon.
Ilaaliyaha hababka heerkulka sare: Iyada oo dhibic dhalaalaysa ay ka sarreyso 2300°C, boron-ka kristalinta wuxuu leeyahay xasillooni kuleyl oo heer sare ah. Inta lagu jiro hababka adag sida koritaanka kiristaalka silikoonka keli ah (habka Czochralski) ama fidinta heerkulka sare/ku-tallaalidda ion-ka, boron-ka kristalinta 6N wuxuu ilaaliyaa xasilloonida qaab-dhismeedka iyada oo aan la soo bandhigin walxaha aan la filayn ee kacsan ama burburka, isagoo hubinaya in habka la xakameyn karo oo lagu celin karo.
Lagu xaqiijiyay codsiyada caalamiga ah ee casriga ah: Doorasho lagu kalsoon yahay oo loogu talagalay macaamiisha Kuuriya iyo Jabbaan
Kiiska 1aad (Soo saaraha wafer silicon semiconductor-ka Koonfurta Kuuriya): Budada boron ee UrbanMines '6N (99.9999% saafi ah, cabbirka walxaha 2-3mm) ayaa loo isticmaalay sidii dopant muhiim ah oo ku jira foornada keli ah ee Czochralski si loogu beero walxo silicon semiconductor ah oo tayo sare leh oo nooca P-nooca ah oo leh kala duwanaansho iska caabin gaar ah oo loogu talagalay soo saarista jajabyada macquulka ah ee horumarsan.
Kiiska 2aad (Soo saaraha qalabka/qalabka silicon-ka ee Jabbaan): UrbanMines waxaa loogu talagalay inay iibsato 6N boron dopant saafi ah (daahirnimo 99.9999%, cabbirka walxaha -4+40 mesh). Dopant-kan waxaa loo isticmaalaa hababka koritaanka epitaxial ama faafinta heerkulka sare si sax ah loogu xakameeyo qaybinta fiirsashada boron ee lakabka epitaxial silicon semiconductor ama gobolka isgoyska, iyadoo la buuxinayo shuruudaha adag ee aaladaha korontada ku shaqeeya ee danab sare leh (sida IGBTs).
Sahayda Shiinaha: Faa'iidooyinka Istaraatiijiyadeed ee 6N Crystalline Boron
Iyadoo la wajahayo baahida sare ee sii kordheysa ee ka imanaysa gobollada muhiimka ah ee semiconductor-ka caalamiga ah sida Kuuriyada Koonfureed, Japan, iyo Mareykanka, shirkaddayadu waxay aasaastay faa'iidooyin wax soo saar iyo sahay muhiim ah oo ku saabsan cilmiga boron-ka saafiga ah ee sare leh:
1. Horumarka tignoolajiyada iyo dhaqaalaha baaxadda leh: Iyada oo loo marayo cilmi-baaris iyo horumarin joogto ah, shirkaddayadu waxay ku guulaysatay habka wax-soo-saarka baaxadda leh ee boron-ka β-rhombohedral-ka ee saafiga sare leh (qaabka ugu xasilloon). Tani waxay noo ogolaanaysaa inaan bixinno heerar dhammaystiran oo nadiif ah, laga bilaabo 99% ilaa 6N (99.9999%) iyo xitaa ka badan. Awooddeenna wax-soo-saarka ee deggan waxay noo ogolaanaysaa inaan la kulanno dalabyo waaweyn oo ka imanaya macaamiisha waaweyn ee adduunka (sida lagu muujiyay baahidayada bishii ee 50kg oo boron aan qaab lahayn oo loogu talagalay codsiyada qorraxda).
2. Nidaamka xakamaynta tayada ee adag: Iyadoo la barbar dhigayo heerarka heerka semiconductor-ka caalamiga ah, waxaanu samaynay nidaam maamul iyo xakamayn aad u nadiif ah oo loogu talagalay hawsha oo dhan, kaas oo daboolaya baaritaanka alaabta ceeriin ah, isku-darka falcelinta, nadiifinta iyo sifaynta (sida dhalaalinta gobolka iyo sifaynta faakuumka), burburinta iyo kala-soocidda, iyo baakadaha. Tani waxay hubinaysaa in dufcad kasta oo ka mid ah kiristaalo boron 6N ah ay leedahay isku-xirnaan aad u fiican oo la raad raaci karo.
3. Awoodaha Habaynta Qoto dheer: Shirkaddayadu si qoto dheer ayay u fahansan tahay shuruudaha saxda ah ee hababka semiconductor-ka ee qaabka boron (granules, budo) iyo cabbirka walxaha (tusaale ahaan, D50 ≤ 10μm, -200 mesh, 1-10mm, 2-4μm, iwm.). Sida ku xusan dukumeentiga, "wax soo saarka gaarka ah sidoo kale waa suurtogal haddii shuruudaha cabbirka walxaha gaarka ah la buuxiyo." Jawaab celintan dabacsan ayaa fure u ah guusha macaamiisha heerka sare ah ee Kuuriyada Koonfureed, Japan, iyo wadamada kale.
4. Iskaashiga Silsiladda Warshadaha iyo Faa'iidooyinka Kharashka: Iyada oo laga faa'iideysanayo nidaam warshadeed oo gudaha ah oo dhammaystiran iyo kheyraadka alaabta ceeriin ah, boron-kayaga kiristalline-ka 6N ma aha oo kaliya inuu hubiyo tayada heerka sare laakiin sidoo kale wuxuu ku faanaa adkeysi silsilad sahay oo heer sare ah iyo tartan kharash oo dhammaystiran, isagoo bixinaya taageero agab oo muhiim ah oo deggan, la isku halleyn karo, iyo mid kharash-ool ah oo loogu talagalay warshadaha wax soo saarka semiconductor-ka adduunka.
