Maaddada silikoonku waa agabka aasaasiga ah iyo kan ugu muhiimsan warshadaha semiconductor.Habka wax-soo-saarka adag ee silsiladda warshadaha semiconductor waa in sidoo kale laga bilaabo wax soo saarka alaabta silikon ee aasaasiga ah.
Monocrystalline silicon qorraxda iftiinka beerta
Silicon Monocrystalline waa nooc ka mid ah silikon elemental ah.Marka silikoonka curiyaha ah ee dhalaalay uu adkeeyo, atamka silikoon waxaa lagu habeeyaa shabag dheeman ah oo loo geliyaa nuclei badan.Haddii nuclei-yadani ay u koraan miro leh jihada isku midka ah ee diyaaradda crystal, mirahan ayaa la isku dari doonaa si ay u noqdaan kuwo silikoon monocrystalline ah.
Silicon Monocrystalline waxay leedahay sifooyin jireed oo bir-ka-soo-bax ah waxayna leedahay korantada korantada oo daciif ah, taasoo kor u kacda heerkulka sii kordhaya.Isla mar ahaantaana, silikoon monocrystalline wuxuu kaloo leeyahay koronto-koronto oo muhiim ah.Silicon monocrystalline ultra-pure waa semiconductor gudaha ah.Dhaqdhaqaaqa silikoon monocrystal ultra-pure waxaa lagu wanaajin karaa iyadoo lagu darayo raadadka ⅢA curiyeyaasha (sida boron), iyo semiconductor nooca P-ga ah ayaa la samayn karaa.Sida ku-darka walxaha raadraaca ⅤA (sida fosfooraska ama arsenic) waxay sidoo kale wanaajin kartaa heerka dhaqdhaqaaqa, samaynta semiconductor silicon ee nooca N.
Polysilicon waa nooc ka mid ah silikon curiye ah.Marka silikoonka curiyaha ah ee dhalaalay ay ku adkeyso xaalada qaboojinta, atamka silikoon waxaa loo habeeyaa nuklei crystal badan oo qaab dheeman ah.Haddii nuclei-yadani ay u koraan miro leh hanuunin kala duwan, mirahani waxay isku daraan oo ay crystallize noqdaan polysilicon.Waxay ka duwan tahay silikoon monocrystalline, oo loo isticmaalo qalabka elektiroonigga ah iyo unugyada qorraxda, iyo silikoon amorphous ah, oo loo isticmaalo aaladaha khafiifka ah iyounugyada qorraxda iftiinka beerta
Farqiga iyo xidhiidhka ka dhexeeya labada
Silikoon monocrystalline ah, qaab dhismeedka kristal waa labbis waxaana lagu aqoonsan karaa muuqaalka direed ee lebbiska ah.Silikoon monocrystalline ah, shabagga crystal ee muunada oo dhan waa mid joogto ah oo aan lahayn xuduud hadhuudh ah.Kiristaalo waaweyn oo keli ah aad bay ugu yar yihiin dabeecadda wayna adagtahay in lagu sameeyo shaybaarka (eeg recrystalization).Taas bedelkeeda, boosaska atamka ee qaab-dhismeedka amorphous waxay ku xaddidan yihiin dalbashada muddada-gaaban.
Wajiyada polycrystalline iyo subcrystalline waxay ka kooban yihiin tiro badan oo kiristaalo yaryar ah ama microcrystals.Polysilicon waa walxo ka samaysan kiristaalo silikoon oo badan oo yaryar.Unugyada polycrystalline waxay ku aqoonsan karaan qaab-dhismeedkooda saamaynta birta ee muuqata.Darajooyinka semiconductor oo ay ku jiraan polysilicon-ga qoraxda ayaa loo beddelaa silikoon monocrystalline, taasoo la macno ah in kiristaalo-ku-xidhan ee aan kala sooc lahayn ee polysilicon-ka loo rogo hal kiristaalo oo weyn.Silikoon Monocrystalline waxaa loo isticmaalaa in lagu sameeyo inta badan aaladaha silikoon-ku-saleysan microelectronic.Polysilicon waxay gaari kartaa 99.9999 nadiif ah.Polysilicon-ka saafiga ah ayaa sidoo kale loo isticmaalaa warshadaha semiconductor, sida 2 - ilaa 3-mitir ulo polysilicon dheer.Warshadaha microelectronics-ka, polysilicon waxay leedahay codsiyo labadaba cabbirka makro iyo micro.Habka wax soo saarka ee silikon monocrystalline waxaa ka mid ah habka Czeckarasky, dhalaalidda aagga iyo habka Bridgman.
Farqiga u dhexeeya polysilicon iyo silikoon monocrystalline ayaa inta badan lagu muujiyaa sifooyinka jirka.Marka la eego sifooyinka farsamada iyo korantada, polysilicon wuu ka hooseeyaa silikon monocrystalline.Polysilicon waxaa loo isticmaali karaa sidii alaab cayriin ah oo lagu sawirayo silikoon monocrystalline.
1. Marka la eego anisotropy ee guryaha farsamada, guryaha indhaha iyo guryaha kulaylka, aad ayey uga yar tahay silikoon monocrystalline.
2. Marka la eego sifooyinka korantada, korantada korantada ee silikoon polycrystalline aad ayey uga yar tahay tan silikoon monocrystalline, ama xitaa ku dhawaad malaha korantada
3, marka la eego dhaqdhaqaaqa kiimikada, farqiga u dhexeeya labadu aad ayuu u yar yahay, guud ahaan isticmaal polysilicon badan
