SIDA LOO SAMEEYO WAFAR SILICON AH

SIDA LOO SAMEEYO WAFAR SILICON AH

A waferwaa jeex silikoon ah oo dhumucdiisu tahay 1 milimitir taasoo leh sagxad aad u fidsan taas oo ay ugu wacan tahay habraacyo farsamo ahaan aad u baahan. Isticmaalka ku xiga ayaa go'aaminaya habka korinta crystal waa in la isticmaalo. Habka Czochralski, tusaale ahaan, silikoon polycrystalline waa la dhalaaley iyo iniin qalin-qafiif ah ayaa lagu rusheeyaa silikoon dhalaalaysa. Kareemka abuurka ayaa markaa la rogaa oo si tartiib ah kor loogu qaadayaa. Colossus aad u culus, monocrystal, ayaa natiijadeeda. Waxaa suurtogal ah in la doorto sifooyinka korantada ee monocrystal iyadoo lagu darayo unugyo yaryar oo saafi ah oo saafi ah. crystals-ka waxaa lagu daraa si waafaqsan tilmaamaha macaamiisha ka dibna la nadiifiyaa oo la gooyaa xaleef. Tallaabooyinka wax soo saarka dheeraadka ah ee kala duwan ka dib, macaamiishu waxay helayaan wafersyada gaarka ah ee baakadaha gaarka ah, taas oo u oggolaanaysa macaamilka inuu isticmaalo wafer isla markiiba khadka wax soo saarka.

HABKA CZOCHRALSKI

Maanta, qayb weyn oo ka mid ah monocrystals silikoon ayaa la koray iyadoo loo eegayo habka Czochralski, kaas oo ku lug leh dhalaalidda polycrystalline silikoon nadiif ah oo nadiif ah oo ku jira quartz quartz hyperpure oo lagu daro dopant (sida caadiga ah B, P, As, Sb). Mid khafiif ah, monocrystalline abuur crystal ah ayaa lagu dhex rusheeyaa silikoon dhalaalay. Karitaan weyn oo CZ ah ayaa markaa ka soo baxaya crystal-kan khafiifka ah. Nidaaminta saxda ah ee heerkulka silikoon dhalaalaysa iyo socodka, crystal-ka iyo wareega wareega, iyo sidoo kale xawaaraha jiidashada crystal natiijada ingot silikon monocrystalline tayo aad u sarreeya.

HABKA Aagga sabeeya

Monocrystals oo la soo saaray iyadoo loo eegayo habka aagga sabaynta ayaa ku habboon in loo isticmaalo qaybaha semiconductor-ka, sida IGBTs. Silikoon ingot polycrystalline cylindrical ah ayaa lagu rakibay gariiradda induction. Aagga korantada ee inta jeer ee raadiyaha ayaa ka caawisa dhalaalidda silikoonka qaybta hoose ee usha. Goobta korantada ee elektiroonigga ah ayaa nidaamisa qulqulka silikoon iyada oo loo marayo dalool yar oo ku yaal gariiradda induction iyo korka monocrystal ee hoos yaal (hab aagga sabaynta). Dawaynta, inta badan leh B ama P, waxa lagu gaaraa in lagu daro walxaha gaaska.
